Maybe they changed the location of the ground wire on your bike. Mine is bolted to the transmission case near where the motor is bolted to the frame. I don't have a spare 550 around to check but that doesn't make a whole lot of sense to bury it where it can't easily be serviced or changed. At any rate any bolt like that should be sprayed with a good penetrating oil before attempting to remove it. If what I suspect is wrong you might have to replace the main ground wire anyway.Last edited by OldVet66; 09-02-2019, 04:30 PM.http://www.thegsresources.com/_forum...ine=1440711157'78 GS1000E, Dyna-S ignition, Dyna Green Coils, K&N pods, Delkevic SS 4-1 exhaust, Dynojet Stage 3 jet kit, Russell SS Brake Lines, Progressive suspension, Compu-Fire series Regulator 55402 and Advmonster cree LED headlight conversion.

I was confusing what bike you had. The 550 is a baby 1000 motor so it will be on top of the transmission just like mine forward of the frame mounting bolt. You have the wrong wire.Last edited by OldVet66; 09-02-2019, 04:26 PM.http://www.thegsresources.com/_forum...ine=1440711157'78 GS1000E, Dyna-S ignition, Dyna Green Coils, K&N pods, Delkevic SS 4-1 exhaust, Dynojet Stage 3 jet kit, Russell SS Brake Lines, Progressive suspension, Compu-Fire series Regulator 55402 and Advmonster cree LED headlight conversion.

I'm following the black battery wire directly from the battery box. It's a couple feet long, one end goes to the battery, the other goes to a screw into the engine casing under the plastic airbox that connects to the carburetor.20190902_154231.jpgLast edited by ZombiePotatoSalad; 09-02-2019, 04:43 PM.1980 GS550E

You can see the picture of the main earth (ground) in the third pic of this old post, at the rear of the transmission case, toward the left hand side.
Things have moved very slowly over the winter, but I've managed to get a few bits done - brake calipers, air filter box, engine mounts etc.
Now to deal with this.......

Ok, I checked all 3 wires coming around the battery box, and connected them. Now when I push the starter button, it won't even turn. The lights still come on, though.
EDIT: Also, my multimeter was going bad. I had to get a new one.
EDIT 2: I see why that is. The Ignition fuse fell out. Gotta find it.Last edited by ZombiePotatoSalad; 09-02-2019, 07:32 PM.1980 GS550E

Alright. I'm thinking it may be the battery ground wire, the runs from the battery negative post.
I had it in one position earlier and got coil 1 to spark, at least for a short time. After 10 or so flashes from the spark plug tester, it stops.
However, the ground wire screw into the engine casing is in a tight spot.1980 GS550E
