Switch wiring
Laverda Dave:
Thanks Bryan. The rear light works on the battery when using the light switch. Indicators work on the battery.
It's not bade easy with the MT125 R/H switch, XL125s L/H switch and a main loom (ot the 3rd I've kept) from an unknown bike. I've been pouring over the wiring diagrams of all three bikes and can't understand why if the black feed cables are live why isn't anything else working. Just taking the horn off now to test it.
Laverda Dave:
Tested the horn on a battery, it works so a wiring fault somewhere.
I solved the brake light problem as well. The brand new front brake brake light switch was faulty, it's permanently on. I swapped it out for a spare one I had for a 400/4 and it now works. So the brake light works (front and back) with the ignition on as it should.
The neutral switch is puzzling, sometimes it will work when the main light switch is operated (but doesn't work when only the ignition is switched on) and sometimes it doesn't.
All frame earths are good.
The relay is definitely working, I can hear it energising when the R/H main light switch is used.
Bryanj:
Dave, i have replied to your email, just in case its hiding again mate!
Laverda Dave:
Hi Bryan, yes thank you for your reply, I'll be out in the garage later this afternoon with a mug of splosh and some renewed enthusiasm 🙂👍.
Bryanj:
OK Dave, while you are there, only reason for neutral light not working when plugged into black is a bad connection or brokenish wire, check the state of the bulb holder as they corrode and the centre contact goes bad
