1990 GL1500 starter running with key off

Postby saltydwg » Fri Jul 01, 2011 11:03 pm



I started my 1990 GL1500 and put it into reverse, backed it up 50 ft stopping three times.
Shifted it into gear and drove a couple of miles. When I stopped I heard the starter making noise and turned the key off and the bike shut down but the starter kept running, turned the key back on and the bike started back up. Pulled the battery cover off and disconnected the battery. I can put the bike in neutral or any gear and connect the battery and the starter will run. Please help me out.

Normally when this happens the A relay is at fault and must be replaced. The A relay is the one alongside the battery, it is best to the replace the B relay also. If not taken care of the starter will burn up.

Thanks trike lady. I'll try both relays. The bike will sit.

The B relay is the one that sits in the lower left hand corner of the frame when you take the side cover off the right hand side of the bike, you'll notice a small silver canister with cables in a rubber boot.
The A relay is a little more involved with the battery box and the relay placement it is far back and along side the battery box.
Always disconnect battery negative cable first when performing any type of electrical work.

Thank you trike lady.
I don't know what I did, and it upsets me, but the problem is fixed.
I spray the starter button with electrical contact cleaner and WD-40. Didn't help
I pulled the relay next to the battery and checked continuity accross terminals and the circuit was open. Tapped it a few times with a hammer and the circuit was still open. Put it back together and tried hooking the battery back up. Starter turned without key on
Disconnected battery and removed nuts from the relay again and left wires loose.
Went back next day and hooked battery bacl up forgetting about not having nuts on the relay and a few sparks shot out from terminals. Disconnected battery and put wires back on relay. Hooked battery up and the starter didn't turn. Turned key on and pushed starter button, bike started right up.
Everything works perfect.
Really being lucky isn't good all the time because I don't know what the problem was.

You probably still have a bad relay. The trouble is, it has temporarily "fixed" itself.

Relay terminals arc when they are pulled together. On relays that carry high amperage, it is like arc welding. That arcing is not seen because it is inside the relay enclosure but there is still arcing. That arcing creates pits and spurs on the contacts. Over time, those pits and spurs will eventually get so bad that they will cause the contacts to stick together and give the malfunction that you experienced. Jostling the relay or hitting it can temporarily break the contacts loose from one another and it will appear that all is well.

Those contacts may not arc weld together for a long time but then again, it may happen in as few as two or three cycles of the starter button. One thing is pretty much as certain as death and taxes, the malfunction will manifest itself at the worst possible moment in time. The best thing to do is to replace the relays and not let it come back to haunt you.

Mike,
Your right, I guess I'll change both relays out. I'm planning a trip from Chincoteague VA down to the Keys via the East Coast and back up the Gulf Coast this summer and don't need this problem again.
