Let us know more details on the fault and we might be able to help e.g. and mods to wiring, have all indicators stopped working, has the flash rate changed, does the indicator warning light still flash, is headlight beam especially bright or dim, did the fault with the headlight and the indicators start at the same time, etc?

hi thanx for replying its really hard to understand that diagram all the indicators have stopped working indicator warnig light dosent flash the headlight beam is really bright and im almost certain they stopped at the same time if anybody has got any instructions of them doing it or pictures how it shold look can they send them in thanx katana for replying hope this helps.

If the headlight is very bright and the fuses keep blowing I would suspect the voltage regulator is faulty.

Get hold of a multimeter (cheap from Maplins – or borrow one) and check the voltage across the headlight with the engine off, at tickover and then rev the engine the voltage should be approx 12volts (unless it is a 6volt system) and shouldn’t vary with engine revs.

Yep, as Katana says, the voltage should be (for a 12 volt system) about 11.5 to 12.5 with engine off and rising to about 13.5 with the engine on. Any more than 14 and your regulator is probably faulty. The regulator does just that – regulates the amount of voltage being supplied to the battery. Faulty batteries or connections can cause some weird symptoms, it’s always worth checking the connections at the battery terminals. Take them off and rub them with some light sandpaper or a wire brush so they make good contact.
Does your battery hold the charge OK?
