Re: 1989 GL1500 On the way home from a trip, I stopped for gas and she wouldn't restart. I got her jumped, and rode until gas was needed again, again a jumping got me home. I have replaced the alternator. Put the battery back on and tried to start. I got all the lights, nice and bright until I tried to start her. There was a small clicking sound, lights dimmed and she wouldn't crank. The battery read about 6 volts after the try. I removed the battery and it read 12+ volts. Reinstalled and tried again. Same thing. WTF? Suggestions?

Be sure the battery terminals and the cables going to it are bright shiny clean, a corroded connection can do this.

If that doesn't help, take the battery down to your local auto parts store and have it charged and load tested.

Yep, ,if you're getting 6+volts with a "load" (starter pushed), your coils won't fire juice to the plugs. Those coils ALWAYS need 10.5+ volts to get the plugs enough power to fire correctly.


Once you get a new (AGM preferably) battery, there is a very cool modification to the coil wiring on here that will help keep those coils firing hotter than the OEM wiring. Its under a thread titled something like, 1500 won't start until release of start button.

The reason it reads 12 volts out of the bike is because there is no load then. It should be closer to 12.7. That .7 volts is very telling. I bet the battery is junk. You have all the symptoms,

He said it read 6 volts "After" the start attempt, but 12+ volts after battery removed. That's what led me to the corroded connection statement. Still likely to be a junk battery though.

I to have an 89 GL1500(now up for sale) that would not start. But would roll start right up, then run off the alt. The trouble was the main fuse screw was louse.
Good luck
