These 1500's are POWER-HOGS at startup. 12v with "no load" and 10v with "load" is a good indicator that your battery needs replacing. Put the battery on a charger and try to get 12.5v or more with "no load". The ECM/coils circuit will want close to 10.7-11.5 volts in order to start that engine. There could be other issues, but the battery is the first place to start IMHO.

There is a great thread about wiring a relay between the coils and the ECM (IIRC) that will give the coils more "juice" to fire up, , it might be a good idea to look at. I'll find that thread and this link comes closest to what I was thinking; ... olved.html

Your battery is very likely dying (and possibly your alternator needs upgrading).

Here's a simple test - With the choke etc. set appropriately, plus give it a bit of throttle & release (for a bit of extra fuel from the accelerator pump), crank the engine for 5-6 seconds. As you release the starter button, it may well start.

The reason is because GL1500's need a LOT of juice to start. While cranking, if the battery is on its way out, there's enough juice to run either the starter, OR the ignition, but NOT BOTH. When you release the starter button, there can be enough left to fire the ignition while the engine is still spinning for a moment, and the engine will start. I've seen this many times before (including on my own bike, with a supposedly quite "new" Odyssey battery). A brand new AGM-type battery fixed it instantly.

I also went with an aftermarket, 95-amp alternator. Now, I have all the juice I can ever need.
