still looking for help with 1200 goldwing the wiring problem

Postby shockdo » Wed Jun 27, 2012 12:58 pm



I'm trying to contact the persons trying to help me with my 1200 goldwing wire problem after trying to start it on a low battery. Here is what I've done to date -
I got a used regulator that was working when bike was striped for parts.
I got another starter relay.
I spoke to my mechanic, to make sure I'm hooking it up correctly.

Now testing results using just a wire tester -
The key off, I have power to both "red" main plug-in wires on the relay and main cable coming from the battery.
The key in "acc" position I still have power on the main power + cable coming from battery and both red wires to the relay. However when I turn the key to "run" I loose the power coming from the main + battery cable at the relay. Turn the key off it comes back. No lights have come on at all this hole time. Next I removed all 4 wires to the relay and plugged them back in one at a time. Doing the same test, I didn't have any problems until the solid red wire was plugged in. My guess would be related to this wire. Any suggestion on where or what to test next?

As soon as you turn the key to the "on" position the bike draws about 10 amp from the battery.

As you mentioned,as soon as one of the red wires is hooked up,you loose volts on the main cable coming from the battery.Soooooo

Use your test light.Attach it DIRECTLY to the battery lugs.Both of them.It obviously will light up.
Turn on the key...It should still be lite.If it goes out....take the battery out and have it load tested.
If it stays on....move the ground part of the test light to the engine block and turn on the key..
If the light goes out,you've lost the ground connection.Usually a corroded lug under the engine bolt.
If it still stays on,the ground is OK,move the test light to the solenoid.
Open the trap door to get to the fuse and probe each side with the key on.both screws should have 12 volts on them.One side goes up to both the red wires.
.Let me know what you find.I have bypassed my red wire solenoid connections completly because of corroded connections.I tied both red wires to a 30 amp fuseholder and attached direct to the battery lug.
By all means,PM me if I lost you,I can step it through with you on the phone.

By the way,if I remember right,the red is the main feed to the bike and the red with the stripe is the output from the regulator,so as soon as you try to draw power is when it goes pu-pu.It's not a fault in the bike,just from the solenoid,wiring to the battery or the battery itself.

Thanks for the better information. One question still, if the red wire is the main power for the bike then why am I not getting a headlight or netural light? I'll run the tests you gave me and get back to you, thanks again.

A corroded connection can allow some current through but as soon as a large load is attached,its too much and the current flow is stopped.
