'78 GL1000 Starter Troubles

Postby monkiesinhell » Thu Jun 23, 2011 8:21 pm



I'm in the middle of restoring a 78 gl1000. I started it up for the first time today. I was looking at the Solenoid and someone had removed one of the hot wires that goes from the battery to the solenoid. I just placed a wire from the solenoid to the battery, and the starter turned right over. I know the previous mechanic just started the bike by jumping the solenoid with a screw driver. I think he may have shorted out the starter because it will not turn the engine over when it is warm, but when it's cool the starter turns fine. Is this my wiring job, or a bad starter?

Starters that run fine cold but not hot are often in need of a cleaning. Many folks replace them, but in my opinion that is silly as these are robust starters and they do not wear out often, but just get carbon build up inside and require a cleaning. There is a most excellent DYI article on this forum to help you with disassembly, and Duplicolor Engine Enamel Aluminum is a very close paint match. So with about an hours work, your starter can turn over whether hot or cold.

Now a damaged wire that gets hot can give a similar result, but I think it is more common to have a carbon buildup inside the starter. Be sure to let us know what you learn.

Did you use the same gauge wire?

I used a bit heavier gauge, because the Honda wire looked way to thin. I actually had the same gauge as Honda did but when I tried it it got way to hot (to the point of frying), so I replaced it with a heavier gauge. This is where I found out that my starter might need rebuilt or replaced, because even the new wire gets warm when trying to turn the starter over while it is warm.

Time to clean the starter out inside then. Keep in mind that a cleaned up stock starter is better than many rebuilts as Honda used very good parts and many rebuilds use inexpensive parts from suppliers that have no real experience.

There are some crap new Chinese made starters out there also. Be careful if you buy new.

What is the proper gauge wire from the solenoid to the starter? Is it copper or aluminum? Copper has less resistance and will carry more current. The wire I have run now came with the bike and LOOKS right but could have been changed. I have rebuilt this entire motorcycle in the past year and the starter is the last hurdle. It is very sluggish.

Hopefully he can get the exhaust stud out, without doing that you can't remove the starter.

Well you can but it's a real process.

Pretty stupid design by Honda but I guess their engineers never thought that the starter would ever require any maintenance.

I'm pretty sure it's 8 gauge wire, and it's definitely copper.

Hey...this will help big! I don't see this mentioned often...while cleaning the brush area, take some sandpaper and clean the edges of the brush plate and the housing where the brush plate seats VARY well. That is a ground condition....you may be amazed the outcome!
My exercise bike is a goldwing.

I had an 84 that would start cold. Once warm, the starter would just grunt. Turned out to be the brush plate not fully grounded. It's pinched between the starter body and end piece and has tabs bent to make connection to the body. Clean these up and add a little spring, bend them slightly to insure good connectivity. This made all the difference in mine.
