I hooked up my R6 battery to the GS and noticed after trying to start it and nothing happened, that I polarities are reversed.  Now after correcting it, the bike wont light up at all.

Have I blown a fuse?

If so, where is the particular one located?

Thanks,

Barna

which wont light up.

the GS500 has a fuse on the right side (under the plastic  - take off seat and right side plastic - right side when your sitting on the bike).

Its in this green and red box.. it says fuse.. pop it open and it should be a fuse in there.. the spare is just outside.

That's an interesting question.  With the battery backwards, you would have had a -12v bike .  The lights and relays should work off negative DC power just fine.  I don't know about the starter.  If it were a simple electric motor, it would try to spin backwards.  But I don't think the would engage the drivetrain properly on -12v power.  The ignition system probably won't work off -12v.

It makes sense to check it, but unless you shorted the ground post of the battery to the chassis, then I can't really think of any reason why the fuse should pop.

I take it that you're using an "alternate" battery?  It would be hard to hook-up the OEM battery backwards, since the cables wouldn't reach.

BTW, if you're worried that the battery is the problem, you can take it out.  I have put a 2x4 across the frame, and screwed the POS and NEG battery cables down to the 2x4; then used jumper cables to connect the cables to a car battery; and used that to do troubleshooting with a "known good" battery. (If you connect to a battery that is still in a car, leave the car turned off!).

Could have cooked the electronics (ignition & regulators)

If the headlights do not come on with the battery properly hooked-up, then it seems like the fuse must be blown: batt->fuse->ignitionKey->headlightSwitch->headlight.  If the R/R had somehow burned-out and failed open, then that could keep the headlights from lighting... but then, the fuse should be popped.  You could unhook the red/black nylon plug to the R/R if you suspect it.

But it seems to me that if good battery yet no headlights, then the fuse must be blown.  I don't know why it should be blown just from hooking up the battery backwards (unless you shorted something too), but it sounds like it did blow.

hopefully a blown fuse would be his only prob. ive been there it cost me major$ in one of my tractors. (id forgot it was positive ground)

It was the fuse!  Thanks guys
