Suddenly loss of power-nothing

Postby larshh » Sat Oct 01, 2016 5:04 am



Hello all
My 88 GL1500 showed me a problem, while on holiday. Suddenly without warning/indication, all power lost. I could get it to run again by turning ignition key on and off a couple of times? I noticed that there were no power at all, so it must be some main connection problem.

1. checked battery cables and found them ok, nothing visible?
2. suspect ignition key switch, but by moving it when fault occured, no changes. Only by turning key off/on, I managed to keep it going.

Has anybody discovered equal problem?

Let me hear some solutions/suggestions?

Thank you all from Denmark and drive safely.

Lars

My first inclination would be either one of the relays on the relay panel behind the front of the left saddlebag, or the kill switch. If the kill switch contacts get dirty, the switch can act as though someone had just reached over & turned off the key. This is not an uncommon problem on the GL1500. As for the relays, #3 seems to be the usual culprit, but I'm not certain if this could cause your particular symptoms.

My first check would be to try switching the kill switch on & off several times when the bike dies this way, and see if it comes back to life. If it does, cleaning the contacts is in order. There's a "how-to" in the GL1500 DIY section here.

Keep us posted!

Hi again

Thank you for a super fast reply, I know that this forum is fast.

I just remembered something, while driving I activated my indicator lights, and the engine died very shortly, but it kept on runnig, I just touched my indicator switch? Does that help explaining my problem?

I will come back as soon as I try the suggestions.

Thanks again

Lars ;)

Hmmm - that might point to one of the relays being the problem. Unfortunately, I'm not at home, so don't have access to the GL1500 manuals. Hopefully, someone will be able to track that for your & determine which (if any) of the relays could be causing the problem.

By the way - the DIY method for checking the relays is to rap on them gently with the handle of a screwdriver (for example), as they are mechanical devices inside, and can stick. The vibration from rapping on them often frees them up, for a while, so you can figure out which one is the problem.

Check the connections under the kill switch. Years and many miles of vibration will cause these screw connections to become loose and then you lose power to ignition and fuel pump.

Those who say it cannot be done should try not to interrupt those who are doing it.

Thanks - I have 2 good suggestions to try out.

1. Relays
2. Kill Switch connections.

I will work on that, now the season is finished i Denmark. But will not be able to check it out before next year.

Thank you all again to live up to super fast reply and good ideas.

Regards,
Lars
