1986 GL1200 SEI no lites on the ECU

Post by sids750s »



I have a 1986 Gl1200 aspencade SEI it wont start. there is no spark. the ECU does not have any lights lit up at all. all the fuses in the fuse box seem to be fine. is there a separate one for the ECU ? my buddy was riding it and stopped at the gas station. and when he came out the bike wouldn't turn over. so he called me. I told him the solenoid was out or maybe the starter. I told him to jump across the terminals on the solenoid. it didn't work. so when I got there I determined the starter was out. after replacing the starter the bike now turns over but doesn't start. he later told me he jumped across the battery terminals not the starter solenoid. so is there a blown fuse or is the whole thing ruined ?

I think that that bike has 2 of those 30 amp dogbone fuses...

There are two 30 amp fuses, one on the starter solenoid itself, and one on the extra wire that is connected to the battery terminal of the starter solenoid. You will find this 30 amp fuse to the rear of the battery tucked in out of sight.

This fused wire controls the CFI main relay, brake light and air pump relays. The important relay is the CFI main relay - no power bike will not start.

What manual do you have? This information is in the electrical troubleshooting manual.

Good luck.

I checked this fuse before. but on second inspection it was bad the "dogbone" fuse looked perfect but it had a hair line crack that broke the circuit I rigged a fuse holder with a 30 amp fuse hooked the battery back up and everything lit up and the bike started right up. thanks for the help.
