I can't reach my wiring diagram from here... GS750ES/EF question.

[Guest]

oops! My manual is in NY and I'm in GA getting ready to head up there on the bike next week. Right now I'm fitting a Bestem 929 trunk and I have limited tools here now so could someone tell me which wires are for the brake light on my bike? In the four pin connector I've got blk/wht, grey, white and brown.

Also does anyone have a good thread on brake pad bedding bookmarked? EBC Organic (On sale at Whole Foods!)

Thanks!

Bump.

I could really use the info if someone has time to check a diagram for me!

I'm firing up the diagram on bikecliff's web site...

wait until it loads.

bedding brakes, 10 moderate stops?

I have no wiring diagram to offer, but can make a suggestion.

If you have a volt-ohmmeter you can do the job easily.

A test light can also work for you.


You have four wires, so it seems almost certain that one wire will be ground, one will be brake, and two will be for directional output.

Connecting one cable from the meter to ground (battery negative/pedal/engine/frame) and then selectively touching the other to the respective contacts on the connector will allow you to determine the purpose of each one.

Check all four wires with the ignition switch "OFF" and you should find ground if using a meter. If using a test light, then to find ground the other cable end should be connected to the positive terminal on the battery. You can also do this with a meter.

All other tests are with the cable end connected to ground/battery etc.


If your connector is not clearly identified as to which should be your right/left orientation use some nail polish or other paint/tape to mark it for easy reference,

Write down on paper what you find with each check.

You need to have the ignition "ON" to do the rest.

Leaving the wire from either a meter or test light attached to the frame /battery or other ground point press the brake pedal and touch the connector contacts individually. One will move the meter or turn on the light. Record that.

Now turn on the signals and repeat....the light on the test unit will flash or the meter will jump/bounce when you hit the correct contact.

That should leave only one untested contact, so the conclusion can be drawn , but test it anyway.

Thanks RustyB! I didn't know BassCliff has the GS750 .pdf on his site, I should have thought to look but thank you for taking the time to look it up and post the diagram for me!

Argongas: No meter or test light here. I'd planned to leave a 12v text light for exactly this (and to have on the road...in case) but it looks like I must have thrown it in a box later on without thinking.

I realized while you guys were posting that I actually DO have a test light, the stop light on the trunk I'm trying to wire in. My next step was to go out and probe the battery side of the connector with the leads from the stop light on the trunk. Thanks for your write up though, it reads well and will probably help out a lot of people here in the future. I know I still find good tips and info in some really old posts!
