Strange Elctrical Problem

Post by jayhawker »



I’m having a very strange electrical problem on my 2001 Goldwing. The first time it happened I was pulling into the garage when the engine dies, the clock and the trip odometers reset, something just happened that the voltage dropped to such a level just like the engine was off and the battery disconnected, but after the event the bike started up and ran fine. I checked to see it the Battery connection were loose but all was tight. Then again yesterday we were getting home from a 150 mile trip we slowed up to cross over some rough rail road tracks and again the engine dies and clock and trip odometers reset to zero. I managed to get the bike restarted before it quit rolling just like before. I’ve noticed lately that when I start the bike then it takes some RPM’s to get the voltage to come it to its usual 14.4 volts. It just seem strange that if the alternator is working and the battery is good how could the voltage drop to such levels that would cause this event yet would be fine in a few seconds. It seems to me the only thing that could seemly affect both the battery and alternator voltage at the same time would be the ignition switch, but under normal operations when the switch is off the clock and trip odometers do not trip. Hoping for some advice as I haven’t the experience to determine the problem and just start changing parts can get expensive.

2 things to scrutinize.
Battery post connections and the dog bone fuse.

I'm afraid I don't know what the dog bone fuse is or where to look for it, can you be more specific? If it was a fuse how would it go about resetting itself in just a matter of seconds but I will check it out when I know what it is and where to find it.

Next to the battery is a plastic cover.Remove to expose the fuse link.Remove it for inspection.They have a tendency to hairline crack.There may be a spare in the cap.

It's an 1800, doesn't have that ancient main fuse. There is a 100 amp main fuse (B) in the fuse box, 2nd from the bottom screwed on, and the #2 30 amp main fuse (A). Check their connections.

Clean the backside of the battery cable plates where they mate to the battery terminals.

How old is the battery? Just a wild guess but I'm thinking the battery itself is momentarily shorting out....

There are heavy duty electrical connectors hiding behind the left saddlebag. I had my bag off last winter as I decided to check and clean out that area. I was somewhat shocked to discover that the nuts holding the ring terminals to the relays were so easy to crack loose, I'm guessing an infant could of cracked them loose. So maybe you should investigate that area? When I reassembled it all I made sure those ring terminals were snug.
