View Full Version : F%^ked up light issue

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

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 :p

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. :zzzz: 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.

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

Thanks in advance all -hopefullywe can get this sussed..needs a WOF ain't gonna get one with this going on.

:love: you babe for all your efforts I know this is pissing you off!

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

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.

There is no relay and Pete he tried your suggestion -still no go....

Ground lead at the battery is good and tight? No paint or rust under the tab where it contacts the frame?
What happens if you take the wire you connected from the bat to the dip switch directly to the light socket?
The supply to the light must go via the ignition switch - unplug / replug the connector on the cable to that switch, look for corrosion/ crap in there maybe.
Electrics are easy to troubleshoot provided you are methodical. Use the meter - find power (ie at the battery) then work your way along the circuit A wiring diagram helps

Striped back all the wiring covering well past the steering stem and all checked all four live wires and earth wires, all good to back inside the frame, continuity tested and shook the living daylights out of the loom and it seems ok.

Did what you said Pete just with the front loom so bypassed the switches and that seemed to work so I retested the switch wires whilst unplugged and they seem alright too.

I don't have any voltage across the live wires and earth wires from the main loom despite having continuity back through to the fuses so I suspect in light of the above I suspect something is wrong between here and the front of the loom, which means pulling the whole fucken thing out. Guess what I'm doing tommorrow:argh:

Edit: I started this before your last post came through Pete, will try in the morrow.

I'm lucky enough to have the factory manual thanks to Pussy, I'm also more than familar with the looms on these bike (not that I wanted to be)
thanks all the same.

A mate's wife had a Jap domestic market SV650 like Number One's, Sully, and he replaced the headlight with the Aussie type one( both lights illuminate on low and high). My mate ended up wiring it up with relays, one each for high and low. I'm not sure whether the service manual covers the lighting system like yours (one projector beam for low, both on high), but it could be worth checking the E02 wiring diagram (it has a light switch and no hazard light), it could be similar.
Can be bloody frustrating!
If you want, I can give my mate a holler and get the finer details off him for what he did. Cheers

I spotted Ms Number One driving her loser cruiser this morning.... so maybe not, or maybe it was 'cause she had Sully One with her..... either way, I spotted you!!!!!

Take the bulb off the bike and wire it up to 12V so its running, and give a tap on something and see if it runs then quits. Once a bulb is stuffed sometimes they will run for a bit as the filament touches - very misleading.

If you are really screwed, I have a non-contact tester I can loan you. You insert it at the fuse and follow the wiring with its wand.


HTH,

Just got a WOF today..care of Skunks tyre and Craigs work on the light. Not sure what he did to be honest...it was all just a huge piss off I think. We won't be on here much anymore either.

Ciao and thanks for all the input everyone :sunny:
