GL1200 guidance from you electrical pros.

Postby 2manywings » Fri Oct 07, 2016 9:18 am



I'm dealing with an '86 Gl1200 asp. with an intermittent electrical problem. The bike will start right up and run just fine, then for no reason, acts like someone hit the kill switch. All of the lights remain on and without touching anything, you can hit the start button and it will fire right up and run fine for another undetermined length of time. It may run for 5 minutes or 30 minutes... "No consistency". It did have some electrical plug issues which I've corrected, and I've gone through and checked and cleaned all others. Like I say, it's like you hit the kill switch. I don't want to just start throwing parts at this thing, so if anyone has run into such an issue, I'd be grateful!

The first thing I would look at is what you've already mentioned - the kill switch. Jiggle the kill switch and see if it comes back. Also work on jiggling the ignition and see if that brings it back. Most definitely this is an electrical issue, it just needs to be isolated.

I had remembered that Honda had an ignition switch recall on some GL1200s, and I had an extra one so I plugged it in (without actually mounting though) without any difference. I'm going to test the pulse generators next. I've already cleaned up some bad connections at the starter relay/main fuse and the infamous stator plug. Then went through and checked and cleaned all connections that I could get at. I also see in the parts breakdown that there is a bank angle sensor. It must be buried up behind the steering neck area. I don't remember them being as big of a problem as they are on the 1500s but it might be worth checking. This bike has a Pow-Pac kit, so I may just bypass it to eliminate any future issues. It's been a while since I've been into the bowels of a 1200, but it's starting to come back to me.

I had the same symptoms on my 86 Interstate. Riding along enjoying the day and it would just turn off the spark. All other systems were fine. It would fire back up again , sometimes right away and other times it would take awhile before firing up. Turned out to be one of the pulse generators slowly died. Installed new( used) set and it runs it should again 8-)

The other problem could be 'Kill' switch.

Never had it happen on my 1200 yet ..... but our '97 1500 trike was doing it on the rare occasion and since I did a cleaning of the engine emergency stop switch ..... it's not done it since.

I had all of the plastic removed except for the fairing itself, so it was easy to check all of the connections and even tried another ignition switch. Narrowed it down to the pulse generators. Someone on another site explained how to test them. Ordered a new set from Partzilla, installed them, and all seems to be well. I've let the bike run for over an hour at least twice now without a it missing a beat. Call it good and move on!
Thanks to all for your thoughts!
