Engine died out on the hightway

Postby uoba » Thu Aug 29, 2013 7:21 pm



Ok guys and gals,
I was enroute from my home to St. Louis, MO this morning. I have looked forward to making this 400 mile trip all summer, so this weekend was going to be it.
I left home at 5:30 AM today and my 1988 Gl1500 was running perfectly, as always. About 145 miles into the trip, with the cruise control set at 60mph, and operating on a nicely paved smooth 4-lane highway in Southern, Tennessee, the engine stopped! It was as if I had turned the ignition switch or the Kill Switch off. It just died. The started spins the motor over quickly. The battery is less than a year old, and spent the winter on a float charger. The engine is not getting any fire. Looking at the wiring diagram, when you press the Cruise control on/off button in, the corresponding indicator light on the dash should light up when the ignition switch is full on. Mine does not. It looks to me like the Cruise and ECU work off the same power sources. I'm thinking fuse or relay, but may be all wet here. I checked the 15 amp fuse in the fuse box, and it's ok. Can you check or swap any of the relays? Could there be more fuses to look at somewhere else on the bike?
Put you thinking caps on and give me some clues as to where else to look before it's off to the dealer.
Thanks,
uoba

Open the gas cap,turn on the key,cycle the kill switch from off to on a few times.Each time it's cycled on,you should hear the pump run for 1second.
I assume it's also dead.
The voltage path for The whole ignition and fuel pump goes from The fuse to the kill switch,to the bank angle sensor,before it gets to the ECM.
I suspect the kill switch or angle sensor. You need to get the right side cover off and a test probe to locate the voltage loss.Even If you don't find it,you could hook up a 15 amp fused wire on the battery and connect it to the ECM hot wire to get it running and back home.If there's a short in the system it will just blow the fuse.

To get you moving again....
Under the handlebar rubber on the right side....
Pull it open to expose the large wire harness.Split it part way open to expose the individual wires.
There should be a black with a white tracer.This wire goes directly to the ECM and ignition coils.
Apply 12 volts to that wire should be able to fire up the bike....with the kill switch off.Just remember you would have to disconnect it to kill the motor.
This bypasses the fuse,relay,bank angle sensor and kill switch.

Oh and yes...#8 relay is at the heart of it...it can be swapped author another one...It should also click when the key is turned on so pay attention to what it does.It helps in troubleshooting.

Special thanks to Virglmoblie!!!!!!!!!
Did a few of the checks you suggested Virg and found that the Stop/Run switch is bad. I jumped the two wires at the switch and VAROOOOMMM!!!!
Thanks again to the Forum and especially to my new best friend in Denham Springs, LA Virglmobile.
If there are any more problems, I'll be back!

Cheers!

I just wanted to let everyone know that my Stop/Run switch body was melted internally.
After being told that Honda doesn't sell these replacement switches, I was able to pick up an entire Right Side handle bar unit off E-Bay for $20.00, and just popped out the Stop/Run switch and installed it into mine. All is now well with the world!!! LOL!!!
Thanks again to everyone for the help!
