I take back my everything works statement. The horn is ify. Works maybe 25-50 percent of the time.

Yeah carrying those things does suck. No, none of the other bulbs worked.

i'd say do a continuity check starting from the bulb and working backwards through the wires once you get the new battery installed...really can't get good info from checking electrical issues with a dead/weak battery. From my experience with dead/weak batteries, the horn is the first thing to get iffy...sounds more less like a broken dog squeak toy...then the flickering of the lights....

not familiar with your bike at all...i just know it sux waitin for answers on the interwebz lol..so any info is potentially good info. Are your fuses intact?

I don't want to ask the dumb question, but are you in neutral? sorry

..figure i'll keep talkin and keep ur thread at the top incase anyone wants to chime in....

Haha, yeah it's in neutral. Thing about the horn though is either it's working or it isn't. I'll definatly do that check once I got the new battery in. Thanks for your help. You should come on the afternoon ride on friday. I'll be there and it should be much warmer than it was on the DC ride.

Test for 12v at the orange wire to the bulb.

If you have 12v there, you have a ground problem that is either the sidestand diode or the neutral switch.

Personally, I would check the neutral switch first.

The procedure is in your Haynes/Chilton manual for that bike.

If you don't have one.

You can download the PDF here

Neutral Switch check/replacement is on page 191.

Wiring diagram is page 202 if you have a GSX-R, page 204 if you have the GSX 750F

Wow, I don't know anything about bike repairs, specifically, but I was going to suggest checking the neutral switch to make sure it's functioning.

On older bikes the neutral saftey switch does wear out. Easy to check per the manual and easy to replace. They cheap to.

That should be interesting. I know my bike has a GSX-R 750 motor out of a 1990 but I'm not sure about the harnes.

Fortunately the wiring for the neutral light is the same for both.
