Ha! Squiz - Aussie slang for ‘take a quick look’!! Thought that may elicit a query or two….!

Yes docc, had a quick squiz at this battery tray drop. Thanks… What a nifty idea….but I will try move the battery as quite small in comparison to the new rubber tray I purchased. I do have some wiggle room….

Thanks again docc, yes, followed your earlier link to the American Digikey webshop (which had already converted prices to Aussie dollars…!) and bought the Picker relays you recommended, plus a few other electrical bits… Here is (to me anyway) the fun part…..while navigating this purchase…before I could get to the payment section…I had to answer an extra set of questions about who I am, my usage of the parts, am I going to on-sell them etc… I thought this must be all part of the USA/China superpower rivalry with the USA being cautious around exporting its technology/sanctions and the like…. The parts arrived swiftly. But to my complete surprise….everything I purchased is made in China!! Sorry if I am off topic but thought humorous in the current volatile climate….regards, tennitragic!

A brief update….new set of relays, DeOxit on the battery terminal connectors and minor tidy up the pack of poo tickets. Haven’t removed the tank but all the other bodywork has had a clean prior to eventual refitting and also a dose of ACF50. Battery remains upright with a new tray and strap. To place side down as others suggested, with so many wires to each terminal did appear to strain some of the more rigid wiring? The seat goes on…just… Waiting on the repaired tachometer (coming from Germany) to finish the task of recommissioning for the local roads… Thanks to all and regards from tennitragic

Pleasing to hear this makes sense!…..Ha! Thankyou audiomick, Weegie and others for the tips regarding potential trouble spots being relay bases under the seat. And suggesting alternative spares for the Bosch headlight relays. Adjusted my order at Digikey. Regards, tennitragic

Besides the great relay tips above, I should clarify for you audiomick….low beam was not working as delivered. Recommended that I swap Pin 86 relay wires. With ignition off, high beam was permanently on. With ignition on, only the flasher (pass to flash) extinguished high beam. When green wire swapped from positive to negative, all lights started working as they should with ignition on. I realise there may be other faults - and will get to these - but at least I have a shot at registering the bike for the road now thanks to you guys… Sorry for any confusion caused….remembering all stages/steps not easy - my notes were pages worth! ha! Regards, tennitragic

Thanks audiomick…will be busy next week checking/cleaning (Bt DeOxit!) electrical connections while waiting for the tachometer fix and a few other parts to arrive from your side of the planet! The green wire error you guys found for me opened “good to do” tasks…. Including relays… Ordering a pack of 10 relays from Digikey….but the Aussie supplier can’t help with Bosch relay 0332019150. Should I stick to this exact Bosch or look for an alternative brand? Regards, tennitragic

Much appreciated this last week…. Next step is fit new parts replacing perished rubber items. Side covers, battery tray….These are due in two weeks so plenty of time to read ‘topic’ posts and assess what I can do myself to the wiring/improvements beyond the ‘great green wire’ fiasco! I’ll be honest and admit limitations….. Thanks to you guys I can now take the bike for a safety check with the road authorities. In my State only 30+ year old vehicles receive any concessions. Previously low-beam not working a big fail! Regards, tennitragic

Reporting back….both green wires disconnected from the battery, ignition off, no high-beam! Image 1 This was a good start….! Then, both green wires were connected to battery negative as many have suggested, ignition on……success!! Image 2 All lights worked as they should do! And to check I didn’t stuff up anything else… she fired up as before! Big thank you fellows….! If any of you fine helpers are in Sydney anytime soon? …..dinner is on me! Regards, tennitragic

Thankyou to all of you…..nice to wake up to a raft of suggestions and possible remedies! Busy (not bike related!) this morning but will have another read of these recent posts and progress methodically through them…report back later. Big regards, tennitragic.

Sorry fellows…losing the plot, ignore first wiring draft…both added red wires attach to positive battery terminal. Might have been on this job too long…!

Thanks to all. Wiring diagram of extra relays below….is this ok? To answer audiomick…86 pin on the relay has 13 volts with ignition off. To docc….will go back to garage in about 1 hr, disconnect green wire from positive terminal and report back… Like ‘many’ have been saying…even to this novice…why have the same colour wiring to both battery terminals? Regards, tennitragic

Thanks again audiomick….I have investigated the wiring and done a first draft of previous owner(s) wiring modification……this is messy so will do another to send to the forum. Should have done this days ago with the benefit of hindsight as the mod appears unfamiliar to you guys. Of note, with the ignition off, pin 86 on low beam relay zero volts and pin 86 on high beam relay 13 volts.

Just confirming again….bike arrived with these mods and faults - front brake light plus low beam not working. The brake issue was just a loose pin on the micro switch and easily fixed with help from posts on this forum. Low beam fix more troublesome…. audiomick - I will do as you say and check the pin 86 voltage, ignition off. Weegie and gstallons - good idea to do a wiring diagram. Was initially thinking this ‘extra wiring’ was “a pack of poo tickets”. But also thinking the wiring with 2 extra relays could be a common improvement for poor headlights, familiar to many forum members who may guide me to the solution. Only now do I realise the mods to my Tenni’s wiring are likely more bespoke! Regards, tennitragic.

Hi gstallons. Sorry for the delay in responding to you… trying to learn on the job. Nothing else tampered with in above scenario - swapped pin 86 relay wires with ignition off and wanted to pass on the results in that high beam permanently on whichever handlebar switch is activated/pressed. With ignition on, switches correct positions, low beam also on. Flash to pass..correct..I read should light up both beams yet in the swapped wire position, with ignition on, this action extinguished both beams. New test….Ignition on, with a charged battery, swapping all relay wires…high beam only lights up correctly via low/high beam red button and position 2 on handlebar switch. Ignition off, pressing low/high beam red button, low beam does flicker. All else dead. I am getting confused so appreciate you fellows may be from my findings! Might be time for me to take it to the Guzzi Sydney workshop I use…our State will require a VIN and safety check for the road anyway - they can have a go at this baffling (to me…) main light issue at the same time.
