75 GL1000 suddenly won't turn over

Postby ChristopherStalken » Fri Jul 31, 2015 11:17 am



I have been working on this new 75 I got for a few weeks now, and I ran into a problem yesterday after I finished bleeding the brakes. It was cranking really slow for about ten seconds, then it just stopped cranking. Full power to everything else. I went down to check wires by the battery (accidentally touched the ground terminal and burnt the piss out of my thumb. Nice little 10mm bolt-shaped burn) and everything seemed to be okay. Now I know it has nothing to do with the brake bleeding, so I'm trying to figure out where the problem could be.

I replaced the 7v regulator to get the fuel and temp gauges working.
I replaced the 12v rectifier a few weeks ago.
the battery has a full charge
It was turning over, just really slowly, now it won't turn over at all.

It was running just fine last week. I've run it for at least 20 minutes every week since I got it.

Any thoughts on what I should check first?

Thanks!

did by chance you touch the starter to see if it was hot? being a 1975 you could have a starter that is very very dirty inside or the brushes are worn out?? :D :D

I did not actually. I was too busy screaming like a little fat girl after I burnt the piss out of my thumb on the battery.



Anywho. The starter was working just fine last week, no slow crank or anything. I am thinking it is possibly the solenoid, but I am not sure if these symptoms add up.

I know what your are saying about your burned thumb :o :o. I only know I had a 82 interstate that did the same thing, worked great for months, then slowed down then out of the blue while cranking it just quit. I had to rebuild and clean it up and it has worked great ever since. rebuild parts were around $50 I believe from bike bandit. you can disconnect the positive battery cable from the starter and direct jump starter to see if it spins properly, if it does then you know to look at the solenoid, the dog bone fuse clean up the ground where you burned your thumb, may even be a bad ground off the starter button?? all possible. :D :D

Yeah I am gonna wait a few hours to go look at it. Currently It's 102 here in Springfield, MO and as a Redhead I will most certainly burn alive before I fix this. Gonna tackle it and test all the stuff that I can around 7pm

I would think you have the right idea, as for me I would find a local tavern to wait it out or camp out next to the refrig lose to my beer supply. you certainly do not want to gt dehydrated in that heat.. :D :D

K so as I was cleaning everything with a wire brush (and gloves) the pin that connects the wire from the solenoid to the starter was sparking like crazy as I went over it. Is that normal?

Ignore this. I found out that it is normal.I was actually able to get the bike to short out to turn on. After I turned it off, however, the starter switch at the handle started smoking out the cracks. And then I lost all my lights. I was able to crank the engine using the solenoid so I know the battery still has juice. I have a feeling the starter switch may be the actual issue here, but the smoke makes me think possibly a ground. No idea about the lights though. I don't have any, not the neutral, headlight or anything.



Thoughts?

loosing all of your power to the lights etc is probably the main fuse. I do not know where the location of the main fuse is on your bike but I believe it is probably around the area of the starter solenoid. might even be a dog bone type which will probably crumble in you fingers the second you touch it. :D :D

Yeah That is what I was thinking. There is a large green fuse right next to the starter solenoid that doesn't look the best. I will replace it. But the smoking has me a bit worried.

check out in the how to do articles on the 1000 and you will find out a lot about your main fuse and other interesting problem solving articles.

Lots of carbon does build up inside the starter and any just replace them. But a good cleaning of the carbon inside the starter makes them work like Mother Honda intended again. Normally the brushes and bearing remain good on these old girls as they just do not get the miles of the newer wings on them.
