GL1500 Starter Motor problem (1988)

Postby dvcruz » Tue Jan 20, 2015 10:33 pm



Hello to all.
We took the starter off my brother's 1500 and put new brushes in. We reinstalled the starter and tried to start the bike. You can hear the starter spinning like mad, but it never engaged the engine. We pulled it out and noticed that when standing behind the starter motor and energizing it, the it ran CCW. We looked at the photos I took before replacing the brushes and notice that one set of brushes cross each other before going into the brush holders. So, we cross the wires and now the starter motor runs in the opposite direction (CW, from behind). We reinstalled the starter motor and now when we push the starter button, nothing happens. It's like the started is stuck trying to turn the engine over.
The battery is fully charged and there were no issues with the engine before we pulled the starter. My brother turned off the bike one day and five minutes later it would not start. After rebuilding the starter, we determined that the solenoid was actually bad, so we replaced that and the starter once again worked (albeit backwards).
My questions:
1 - which way should the starter turn when standing behind it?
2 - any idea why the starter cannot rotate the engine?
We are going to pull the spark plugs and see if we can put the bike in gear and rotate the rear wheel to see if the engine is free. If it is, we might try push starting the bike.
Any thoughts?
Thanks.

Am mostly certain standing behind bike looking forward the starter motor is supposed to turn CW. Great care must be taken when installing starter that it goes in with the front splines and outer gear teeth properly meshing their respective driven components. Getting it in by tightening starter bolts only is a recipe for disaster.

When pushing starter button do the running lights dim? Is there battery voltage at both main lugs of relay A to the right of battery when it clicks during starter button push?
This is what I do

We are certain that it has to turn CW. If you stick your fingers in the engine and try turning the sprocket with your finger, it freewheels to in one direction (CCW) but not the other. That was our clue that we were spinning it backwards. After correcting the direction, it was kind of unnerving to have it do nothing - it seemed like it was jamming somewhere. We didn't know if we should keep trying to start it for fear of damaging something.
I was very careful about installing it. Having worked on GWs since 1983, I know how the splines need to line up - once you find the sweet spot, the starter just drops in. So I think we're ok there.
Yes, the lights dim and we can hear the solenoid click. I'll check the voltage at relay A.
Thank you.

That is a 2 post starter, power from A relay going in and relay B to the left of battery is also supposed to close to complete the ground side of starter from the other post if all safety interlock conditions met. One post hot the other minus which completes the circuit for turning the starter.

The starter could have an internal short to the starter body which is why it will turn when removed but not bolted in with another path to ground. Internal short would dim the lights and cause no turning. Recheck brush leads that they are isolated from body of starter where required.

Remove ground side wire of starter and push button again checking lights for dimming (battery draw), if dimming, starter is internally shorted.

Okay, sounds good. We'll check on this. Might take a couple of days, but I'll let you know how it checks out.
thank you.

Ok. Well pulled the starter out, determined it was shorting out on one set of brushes, used a battery to make sure it would spin when power was put to it and reinstalled it. When we push the started button, we can hear switches A and B clicking, but that's all. The starter motor doesn't even begin to crank the engine. Battery voltage is 12.3v and of course the bike is in neutral.
Next step is to pull the plugs and try to rotate the engine manually.
Any other thoughts?

I probably would have tried that first (pulling plugs and rotating engine). Let us know if that works at all.

Just an update - problem fixed.
CT1500 you were right, the brushes were shorting against the casing. Even after correcting that, the bike still wouldn't start. Finally figured out it was in what I call "false neutral". I had a CB750 that would occasionally do the same thing. The neutral was on and the wheels would turn, but the switch wasn't quite engaged (or disengaged). By rolling the bike slightly, pulling in the clutch and stomping on the gear shift lever, the neutral switch would work properly and the fine would be fine after that. Don't know why that happens some times, but it does.
So, thanks for your help and the bike is fine now.
