Guest goosesport Posted July 24, 2003 Posted July 24, 2003 V11 Sport electrical gremlins I am baffled by the electrical problems I’m having with my recently acquired 2001 V11 Sport. Please point me in the right direction to a solution: Problems: 1.Intermittent failure to turn over the starter motor. Most of the time it works but sometimes not. Same thing hot or cold. 2.Brake light fails to light up with either brake. However it will light up a low wattage test lamp. Tail light functions. 3.Tachometer cuts out when parking lights are switched on or brake lever pulled. 4.Oil pressure light never lit up until yesterday when the starter would not crank.. Battery is charged and connection cleaned. Swapped the Siemans relays around and cleaned contacts. What next?
Guest jeremy Posted July 24, 2003 Posted July 24, 2003 unfortunatly the next step is to take and clean every ground conection on the entire bike. this was comon with older spine frames and can give some sports trouble, after that start pulling apart connections and cleaning.
al_roethlisberger Posted July 24, 2003 Posted July 24, 2003 That.. and the current relays, as the original relays are problematic. For ~$30 you can replace them all. Check www.guzzitech.com for more info... al
callison Posted July 25, 2003 Posted July 25, 2003 Referring to V11 Sport Wiring Schematic you seem to have a short or a bad regulator. Everything you mention, at some point or the other, is powered off of the same 12V line that is fed from the regulator which in turn is fed by fuse #3.
dlaing Posted July 25, 2003 Posted July 25, 2003 I had a similar problem this past weekend. the Tachometer went out, I cursed! I filled up with gas and it would not start, I cursed again! I pushed down on the fuses, and then it started. I drove home and it lost ignition a couple of times and stalled twice. And then it would not start again. I switched all the relays around and then it worked. I noticed that if I leave the middle relay out, everything still works, what it up with that??? I think I'll order another set of relays from Dan P.
mikie Posted July 25, 2003 Posted July 25, 2003 [That.. and the current relays, as the original relays are problematic. For ~$30 you can replace them all.] I was going to pick up a spare relay last weekend at ProItalia, until the parts guy quoted me a price of $37.00 for one! Where do you get them?
al_roethlisberger Posted July 25, 2003 Posted July 25, 2003 ...yep, don't waste your time and money getting OEM relays from your MG dealer, although the new "tall" ones should be fine. For a lot less $$, check out: http://www.guzzitech.com/Relays.html al
Guest oldtoolie Posted July 25, 2003 Posted July 25, 2003 Yep, it was the relays. I trekked over to MotoMecca at lunch -- £47 the set of Bosch but satisfaction achieved. Everything works now and the rains have gone. The weekend beckons. goosesport oldtoolie
Cliff Posted July 25, 2003 Posted July 25, 2003 I'm always impressed by the range of problems the relays can produce.
callison Posted July 25, 2003 Posted July 25, 2003 So much for my assessment of the problem. I'm going to go sit in the corner now. Relay, I mean really...
dlaing Posted July 26, 2003 Posted July 26, 2003 So much for my assessment of the problem. I'm going to go sit in the corner now. Relay, I mean really... couldn't voltage drops due to bad connections cause the relay to fail. For example if the relay is only getting say 10.9 V rather than say 11.3 V, then it might not activate, especially if the relay is getting old and tire. So relay, I mean really the problem still could be a bad connection that makes the problem worse when the relay does not click over due to a lack of voltage, or the relay does not click over with enough force to get a good connection.
callison Posted July 26, 2003 Posted July 26, 2003 couldn't voltage drops due to bad connections cause the relay to fail. Absolutely. And it is for this very reason that I started doing the color schematics for Guzzis. I had to push my Sport 1100i twice because of a poor connection that prevented the power relay for the ECU to activate. A bad connector that wasn't on the diagram was the culprit. After that experience, I thought I would make sure the schematic was updated.
mikie Posted July 27, 2003 Posted July 27, 2003 It was a bad realy connection (fuel pump relay) that had me pushing my bike the last mile to work a couple of weeks ago. Fixed that up and it's been fine ever since.
callison Posted July 27, 2003 Posted July 27, 2003 I'm still running the original relays in my Sport 1100i. 57K+ miles. One stuck once. A tap and it worked again. I ran the original relays in my V11 Sport to 22,000 miles and they were replaced while looking for another problem. You neve know with Guzzi's just which electrical malady will rear its ugly little head.
Guest PAULSMART Posted July 28, 2003 Posted July 28, 2003 Yep, it was the relays. I trekked over to MotoMecca at lunch -- £47 the setof Bosch but satisfaction achieved. Everything works now and the rains have gone. The weekend beckons. goosesport oldtoolie I replaced all my relays with Bosch ones over the weekend - instant cure all ! - I obtained mine from a Bosch automotive supplier - via Bosch web site - cost £5 each - a bit cheaper than Motomecca but not as cheap as the States - But what price can you put on preventing a breakdown !!
