  1. As he said, the charging system is not working, The horn shares a circuit with the voltage regulator. http://www.thisoldtractor.com/guzzi007/schematics/1999_V11_sport.gif The circuit goes battery, fuse 5, Starter relay, headlight relay to the Horn & Regulator. Find out why the horn is not working and that will fix your charging Check your Starter Relay, it must be a 5 pin one in that location. Check the relay sockets, could also be loose also. Relay Base Repair.pdf Charging Problems.pdf Provide a better ground for the regulator, a short wire to a timing cover bolt works well/ Good luck Roy
  2. These are the ones I bought http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=Z2247-ND Omrons, made in USA Buy all SPDT type, they work for any position www.digikey.com they also have the little microswitches "Cherry"that go in your levers
  3. I seem to recall you have to be very carefull with a washer on the drive side, if it slips out of alignment while you are putting things together it's possible to put side thrust on one of the bearings. Perhaps someone else will chime in on this. Roy
  4. About a year back I purchased the last of his brake pedals along with a pair of engine gaurds. The brake pedal is far better made (and stronger) than the original part. I just had a note from Joe to say he has run off another batch http://www.swva.net/jkenny/ it's also on ebay item 350469263868 No, I'm not on commission
  5. Thanks for that, armed with a part No at least I have a fighting chance at the local auto parts. Without that they have to know what year, model and engine size it comes from so they can look it up. I'm talking Canadian Tire here.
  6. Hi, the switch on my V11 Sport gave up, it no longer closes the circuit when stopped. I read somewhere here that an automotive one will fit. Anyone have any idea which vehicle and a part No? Thanks Roy
  7. Like Felix420 I have the K&N pods because they look much better and without the air box you can see the rear suspension. As for filtering perhaps they don't work as well but then I don't ride on dusty roads. Back in the 60s none of the Brit bikes even had a filter. Like felix I used the original rubber hoses to keep the intake length correct, this fixed the flat spot. No I don't have a dyno but I do have MyECU so I can hook my laptop up and twiddle with the map. I am currently running a map developed by Raz. Using a gizmo I cobbled together I have the ability to offset my TPS voltage on the fly, this in theory will cause the mixture to change. I plan on adding a temperature sensor to the exhaust to see what temperature effect changing the mix has.
  8. Have you tried to dismantle the angle drive, perhaps it's something you can fix. Pull it apart and post a picture of the offending bits, someone may have the part you need. You should also fix up the outer cable where it is damaged with some electrical tape, remove the inner cable and make sure it's in good shape also.
  9. Thank you. I like the pods as well but the ones with the metal intake horns. Then I saw on a Japanese site a battery tray for fitting up under the tank when removing the intake box. That'd work in well for further plans I have if I keep this bike. That's a good idea, I thought I would put a box under there for my excess tools, air compressor etc but it makes more sense to put the battery there and have a toolbox where the battery now resides.
  10. Where did you end up mounting the sensor that's in the airbox? First of all I just ty-wraped it under the tank, seemed to be OK but after some thought I extended it out into the fresh air. I cut the sensor off the plug and soldered a couple of feet of wire between it and the plug. This avoided having to open the loom. I just ty-wraped it to one of the frame tubes I extended the breather hose down by the gear change and finished it off with a crankcase breather from K&N. Roy
  11. The pods do look cool IMHO but certainly narrow down the power band. If you decide to go that way get the ones with a slight angle, I bought straight ones. The large cable loom you can see has since been re-routed up under the seat with the excess where the air box used to be. This was done without disconnecting anything. As I said they do narrow down the power band, I have since modified the arrangement by extending the pods using the original air box rubber arrangement like a velocity stack, The pods slipped inside and I secured them with a couple of self tappers. That seemed to restore the power band to where it was. I rode in the rain a lot last year, when I changed the oil this season I found a small pocket of emulsified oil in the sump, I don't know if having the pods caused that. Cheers Roy
  12. If you have an LED lamp it's quite possible for it to light in wet weather however I wouldn't expect an incandescent to do the same. Provided the lamp is OK it should come on without the engine running and go off once it starts. I have found a regulator with open circuit in the light wire (39 Ohm resistor burnt out, I suspect a shorted lampholder caused this) however it still regulates fine, operating the light is a seperate task. cct attached Regulator Schematic - With Notes.pdf
  13. No, don't dissconnect it, fix the wires back on and strap them to the valve body so they don't flex right at the joint or replace with a manual as others have. My 2001 still has the electric fuel cock, works fine for me. Roy
  14. That's why it ran fine after I ran another ground wire: probably not because of the wire, but because the battery was fully charged again. I'm still puzzled why the voltage dropped to normal values then, and not anymore. Yes, you are right on all 4 points, the regulator at least the one I have regulates at 13.9 Volts, anything over that it starts turning off the SCRs When you measure the Voltage between regulator Black and the case it should be ~14Volts Between the case and an engine bolt should be 0.0 Volts Between battery positive and black wire should be quite low, I suspect perhaps a little more with the headlight on. If you have a suitable ammeter you could connect it in series with the red wires from the regulator. Re the ground wire, my bike had one of those too, a tiny wire about 20 gauge, totally useless when you consider the current can be upwards of 30 Amps. I added a #12 bolted to one of the fins and run to a timing cover bolt, I'm not sugesting you have to do that but at least make sure your ground has a good connection to the case by filing it to remove any Oxide and add a bit of grease to stop it oxidizing. To add to the problem the mounting bracket the regulator is bolted to is not part of the chassis, it's a small bracket held on by the horn mounting bolts, Luigi really screwed up on that one, so run your ground around that also. Re the generator light, if it's working it should always come on when you turn the key on, if it doesn't that points also to loss of reference voltage, it recieves power from the same red/black wire that supplies voltage reference so you would assume that when it doesn't operate you don't have Voltage reference either or it could be too low to light the lamp but just enough to turn the regulator on hard. Does the oil pressure light come on? If you refer to the schematic the reference voltage turns on Q3 to ground the light and pulses from the alternator turn Q3 off again. Funny that your light doesn't work then comes back after you turn it off and on again, could that somehow point to the ignition switch? Headlight relay not picking up for instance?, next time it happens check that your headlight goes. I think if you can find out why the generator light doesn't come on you may also solve the overcharging issue if you are testing ground the white wire for a second to test the lamp first if it doesn't go you have a problem with the light or no reference. (bear in mind the lights are junk so it could be a faulty lamp holder, thats why you test it first) I think at this stage I would be riding with a multimeter strapped to the tank connected to various points e.g Battery + to ground, Regulator black to ground, battery + to regulator black. BTW the red/black wire does branch off just as shown in the diagrams, when I was troubleshooting mine I opened up the loom sure enough I found wires twisted together and soldered, very well done though so I wouldn't worry on that score. It might just be your regulator is shot but don't give up on it yet until you have taken a few readings. I would start by monitoring the reference to case I think make sure you always see 12V+ when you turn the key on and it never goes beyond nominal 14 Let me know Roy p.s. I have a 2001 V11 Sport also, a Green one
  15. The headlight loads up the circuit causing voltage drop which makes the regulator think "hello, I need to charge the battery" There should be no Voltage drop between the battery Positive terminal and the black wire at the regulator. Any drop will be added back to the battery until the regulator sees ~14 Volts.
  16. Don't forget the ignition switch, that can also cause rough running if the contact resistance is too high, I'm not quite sure how, but I suspect the ECU relays start to chatter. It only takes a second to check because the test points are under the seat from fuse to relay base contact. Should be BTW, which bike/year are you refering to?
  17. When your battery is reading high try reading between the regulator frame and the black reference wire, I think you will find it at nominal 14 Volts. Then measure between battery + and the reference wire, you will find the difference. Of course if you do see 17 Volts between reference and the regulator case it points to a bad regulator. The generator light (assuming it has a good lamp) should come on any time the key is on without the motor running, your symptoms tell me you are either loosing the power on the red/black wire from the headlight relay or you have no ground at all on the regulator. Actually reading back over your first post you mentioned the strange behaviour, sorry I missed that, two different problems in one thread is messing with my head A high Voltage at the battery will cause the ECU to shut down. Remember, if the regulator can't tell what the battery Voltage is, it can't possibly control it, simple as that!
  18. I think it's pretty much the same drawing but do you know it's the right one for your bike? The missing blue wire goes to the generator light. Around 2000 Luigi started wiring the reference through the ignition switch on some bikes so check for voltage at the headlight relay socket withe the key off. (the 30 contact is the large one by itself, it should have power unless the start relay is energized) Other places you might loose voltage would be at the fuse contacts, relay base contacts, relays perhaps but not likely. Try wiggling the relays while watching your meter or swapping the two relays with another pair. You have added a ground strap to your regulator haven't you? Added any other driving lights? One improvement you could make would be to add headlight relays powered from a new fuse at the battery, that would eliminate the load on red/black wire and improve your lights in one go. I would try to fix it this way first because you do have a resistance somewhere that might get worse. Good Luck Roy
  19. At 1000 revs the bike is loosing charge, the battery wont go flat but the voltage will drop, the red light is OK. I'm sure the miss at idle is something else, I call it the Italian Sneeze, mine does that too. Opening the valve clearence seemed to help.
  20. That's not good How much other damage did you sustain? Roy
  21. Cliff, that's interesting, it can't have always been that way, I suspect you have a bike where the reference goes thru the Ignition switch, the headlight creates 3 wolts drop across the switch because it's contacts are bad, either that or you have a high resistance in one of the other points i.e. relay base contact, my bet would be the switch, time to clean that. It's also been confirmed a bad contact at the switch can make the bike run rough. MyECU
  22. Perhaps on your bike, my 2001 V11 Sport is that way also, however on many bikes the reference also passes through the Ignition switch. If you look at Carls drawing for any of the ones below you will see what I mean 88 California,93 Sport 1100, 94 California, 96 Strada, 96 California, 2000 Bassa, 200 Jackal, 2002 Stone The 88 Cali goes Battery - Starter Solenoid - connector - ign sw - connector - 2 fuses at top of (29) -headlight relay - regulator If you look at 2004 V11 Sport you will see the new regulator (with diode symbol). It's wired more directly to the battery, just through a fuse, doesn't have a reference but has no charge light. I haven't seen one of these but I think it must get it's working voltage from the alternator rather than the battery. It's also nice that it doesnt rely on a case to chassis connection but has seperate wires for the Negative.
  23. I have been studying Carls drawings, I used to assume all the regulator problems were caused by bad grounding. I assumed the bikes were wired similar to my V11 Sport but I found a lot are worse with the reference voltage dependent on a good ignition switch contact. I welcome any critique you may have on attached Charging Problems.pdf Roy
  24. Check the Diodes and get back to me. Roy
