82 GL1100 Starter Relay Problems

Postby gaillarry » Fri Oct 12, 2012 9:53 am



Bringing an 82 back to life. Bike had a Ford starter relay installed, removed it as it was a hunk of rust.

Using a 2 wire starter relay from another bike (relay works) and following the info here:
http://gl1200goldwings.com/techcenter/article1004.htm I have the same wiring colours on my Gl1100.

Got it wired per the instructions. Pushing the starter button there's power to the relay but the relay isn't turning the starter. Using a screwdriver I can jump the terminals and the starter works. Thinking this relay is a dud, went to the dealer and got a new aftermarket 2 wire relay. Wired it up, same thing again - power to the relay when I hit the starter button but nothing to the starter.
Now I'm stumped???

Question...the 2 wires....they are used to energize the relay...one wire has 12 volts on it when you push the start button,the other goes to ground through the neutral switch or clutch switch.
Does the solenoid "click"when you push the button???
Is the neutral light on.??

Yes, getting 12volts on one wire to the relay when I push the start button. Neutral light is on, no click from the solenoid.

OK,here's the schematic....It sounds like the solenoid does not have a ground.
First.pull in the clutch lever and try again to crank it.
If it cranks or at least the solenoid clicks,the diode is bad.

I suspect that if you measure..you will find volts on both wires when you push the start button.

Clutch lever out - power on both wires when button pushed

Clutch lever in - constant power on both wires - don't need to push the start button.

Power on both wires,clutch lever out,neutral light on is a open diode.
I just can't determine the other one.
Power on both wires with the clutch pulled in and not pushing the start button.
The wire gets it's power from the start button.
Unhook the solenoid wires,verify which one has power with the start button.
Verify that neither solenoid terminals have power on them.
Hook up only the start button wire.
Attach the other terminal to ground(effectively bypassing the entire neutral safety circuits) and test.It should click.
If it does,work on the clutch switch circuit.it is just a switch to ground.when it's switched,it shorts that same terminal to ground.
Master that one and then go to the diode.It separates the neutral light from the clutch switch.
Keep us posted please.

Thanks for the info, followed your instructions:

1) clutch lever in

2) Wires disconnected from relay only 1 wire with power when start button pushed.

3) Power wire from start button to one wire on relay and other wire to ground.

4) nothing from the relay, checked and there's power to the relay when the button is pushed.

Bum relay??

Not confirmed yet.The wire that goes to 12 volts when you push the start button,your saying that when the ground wire is hooked up it won't go to 12 volts when you push the start button?
Does the neutral light stay on?

Just double checked my connections. Yes, there is 12 volts from pushing the start button to relay with the other wire grounded, but no clicking from the relay.

Forgot to add the neutral light is on.

It sound like you confirmed that the coil part of the solenoid is bad.12 volts on one terminal and ground on the other should energize(click) the solenoid.I am referring to the small connectors,not the big lugs(just for clarity).
The start solenoid is just a electric switch,apply power to the coil and it snaps a large switch closed,that's all there is to it.
Nothing you did should have damaged it in any way.
A new solenoid can be tested by 2 wires from the battery,one ground on one terminal and the other touched to the positive terminal and' click'

Keep us posted please.

Borrowed a relay from a buddy. One wire to the start button and the other to ground. Hit the start button and the starter engages :D :D

Bad clutch safety switch?

so another one worked where yours wouldnt.?
a good confirmation that yours is bad.
Now onto the safety circuit,obviously the start button works OK.
The ground wire you used,should be able to be replaced by the bikes wire.
The green/ red wire should provide a ground by the clutch switch when the lever is squeezed.This operates the switch.
When that method is not used( pulling in the clutch),the ground is provided by the diode and the neutral switch.
I assume that it's OK because your neutral light works.
