electrical prob

[vela]

put my bike in the garage to get, new led sidelights/new drl`s ( these are wired straight to battery as they are switched) / usb (switched also) and led indicators, went to collect bike started it up and started driving, got about 100m engine light came on and fuel gauge was reading zero ( nearly a full tank of juice) took it back but cant find the problem, they fitted resistors to the led indicators but should they have fitted a relay? anyone had this problem at all? i have had to leave it at the garage as they cant seem to sort it , the sidelights wouldn't work either so put old ones back in hope someone knows, cheers

You need to tell us what year! If it's a TS, the indicators are driven direct from the instrument panel, you cannot use a relay. But in theory adding the resistors should be fine.

In practice, unless your man in the garage is a hugely competent vehicle electrician, there's a fair chance he's cocked up somewhere with all those modifications. Could be any one of them. Solving it might mean taking it back to original one change at a time.

I thought installing required a diode with a resistor plug inline or a electronic turn signal relay was required.

Anything else done?
Fuel gauge not registering is very often clutch switch.

I wonder if it's cos both bundles of wires have not been put back on the earth point?  I can imagine one not connected but just touching, and over the first bump it disconnects and...

problem was , if you disconnect the battery, it needs driven for about quarter of a mile then it resets, everything is working just chippa now

Turn them around, they're diodes so polarity sensitive.
