F%^ked up light issue

**Sully60** · 9th August 2008, 16:05

The lights suddenly stopped working on Number One's SV on Wednesday night, just as I was about to head of for work

So I've pulled everything apart and checked all the wiring for obvious faults and found nothing and the bulb is ok (tested that on another battery)

I've checked the continuity of all the lighting circuitry and it all checks out fine.

I get voltage at both the bulb plugs which was 11.4 with the engine not running and 13 and a bit when it does.

I just had Skunk and Sketchy Racer round borrowing bits out of my garage, so I showed them what was happening after charging the battery and low and behold, no problem.

So I leave the battery on charge for a bit longer and try again, all ok, then I start the engine and check again, no go.

I think I've checked everything, there is no relay for the lighting as each beam has it's own independant circuit.

My question is there something else I should check? Bear in mind there is no switch to turn the lights on and of only the dipper switch and the pass switch which I've also tested independently of the rest of the loom.

I'm getting very frustrated now so I'm puting it out here, help!

Fuse... ??? check they are seated firmly... loose connection maybe... give the loom a wiggle where you can see it.

Check the bulb socket... What the bulb is HELD BY. bit of crud would do it. Bit of CRC perhaps ????

It's ok Sully, my mighty presences fixes everything doesn't it

Ground path between light sockets (and ground)? If you are checking with a meter between the active pins of the socket and frame ground you could be bypassing a faulty ground circuit.

Just checked and both high and low earth wires (everthing is plastic around the headlights) have continuity to the chassis.

I rechecked and now the meter is reading .2v on each circuit, what the?

Yes FJ all fuses intact, all wiring connections show continuity either side, I've checked everything I can think of.

typical shit suzuki loom. Be a broken wire (mayb) or a grounding issue. I'd be placing bets on a broke wire.

Have to wiggle each wire til ya find it.

I know

or just rewire the light circuit an replace suzuki's cheap shitty effort.

never would've happened if ya bought a Kawasucky

Check that the wires in the loom havnt broken. They usually break around the steering stem.

**pete376403** · 9th August 2008, 17:05

Break in the wiring. That both hi and lo are reading the same would indicate the break is before the dip switch. I'd be looking at the loom where it bends around the steering head. To prove the point, run a wire straight from the battery to the dip switch

You sound like a chap that could use a cheap j-lo

. Aint no probs with lights on her. she aint got any BWAHAHAHAHAHAHA

He's about to try this...thanks Pete

I don' know about the suzuki, but kawasakis have a relay hidden away... it is powered up by the alternator. The idea is, that when you turn the key on, the lights stay off. So you don't have the lights as a extra drag on the battery while cranking the engine. Once the engine starts, the alternator pulls the relay in, and lights start.
