Engine cut out problem

[cresad]

Hi all

I've got a 2002 Suzuki bandit 600s that cut out on me just after turning at a set of lights. I pressed the indicators off and the engine just stopped. I've got nothing happening when I press the starter button and it has blown the ignition fuse.

I've tried changing the flasher relay , as it happened when I pushed the indicators off , and the starter relay with no change. I've also disconected the – flasher relay , horns , neutral switch , clutch switched , the new headlight relays that I'd put on amd then the whole new wiring all with the same result blown fuse.
Both of my multimeters are marked 10amp on the current measurement so no good when I'm blowing 10a fuses.

Not sure where to go from here

Thanks , Adam

I'd be looking at the headstock to check for wires that had lost some of their insulation. It might be related to the switch press to deactivate the indicators, but might it also be related to turning the bars perhaps? Sounds like a short somewhere, I'd be looking at a wiring diagram and continuity testing everything from the bars backwards.

As per Marjay, that bike could have all manner of age related issues
that go ignored until they play up.
I picked up an old bike dead cheap once where the PO had played
'swap and hope' to no avail and basically gave it away.
A quick continuity test showed a cable near the headstock which supplied power to the solenoid had broken and for me, it was a quick fix.

I have a wee trick I sometimes use to find an intermittant short. If you fit a bulb holder with two flying leads with spade connectors on, you can install it where the blowing fuse goes.

Since you now have a load in there, it's no longer a short circuit. The bulb will light instead of the fuse blowing. Then start disconnecting stuff methodically until it goes out/dims and you've located the short.

Thanks for the quick reply’s
The new relays are a pair , one each for the 2 lights , low and main , as they were both dim . Since the new year dogding the rain I’ve changed the headlight unit ( faired bandit ) and fitted the relays to brighten them.
Just ordered a 20a multimeter to try a similar thing to using a bulb

Thanks , Adam

Just be aware that a 20 Amp multimeter will only be rated to carry current for a short time - something like 10 or 20 seconds. You can't just put it in circuit and let it operate while you look for the fault.

I suppose it would find the fault though. Just hook up a 20A meter in place of the fuse then replace all the wires that are on fire.

continuity check on the alternator .. looking for a burnt out phase...
