Loss of power

Post by bjcrit » Mon Dec 03, 2012 1:56 pm

Hello all, Merry Christmas;
I have an 81 GL1100 STD with approx 55K miles on her.
The other day I went out to ride her to work put the key like always, and nothing, no light or anything.
I have since checked the "main fuse" and it is still good, battery is fully charged, connection on battery trerminals are clean, but while checking the main fuse I did notice that the wiring bundle that runs from the main fuse to the rest of the bike is broken and a couple of the wires are bare. It looks as though I will have to replace those wires that look burnt and frayed.
Is there another fuse or something that could have "blown" due to a short in that bundle? I have checked the main fuse box in the shell but they all look good.
Quite frustrating and with myself not being much of a mechanic, I'm stuck.

Someone else will chime in here on your problem. On most wings there are three yellow wires that go to the rectifier, just before the battery, which you should check out. They are known to get hot and melt the connectors that they go into.

Merry Christmas to you as well. I will ask a few questions, just to help us remedy your problem. Like WingAdmin asked, please list the wires that are "broken". How did they come to be broken? A broken wire is a very suspicious statement. Did they get hot and short out? Did someone cut them? Did the bike fall and cause the wires to break? Also, did the bike run fine when you were riding it the last time? Did you notice anything running differently when you rode it last?

One thing for sure you want to do is, before you do the repairs on the bad wires in the bundle, make sure they haven't shorted out against the frame anywhere else because of the heat melting the wires, by using a continuity tester from the bare wire to the frame. Remove the battery connections before you do this. Then post which wires are broken, or burnt. We do like to help people on here, but sometimes just need a little more information.

Sorry for the mis que. The wires aren't really broken, but the plastic connector that holds the wires is burnt and melted. The wires should be held in the plastic connector, but two of them are not anymore (the two that are bare.
The wires are:
1. Larger solid red wire
2. Smaller green with red stripe
The green one looks as though it has some corrosion around the frayed wires
The plastic connector that holds all four of the wires looks to have some black marks on it like it got shorted and burnt/melted.
The bike ran fine when I rode it last approx two weeks ago. It has been on the center stand and plugged into the batt maintainer.

By your description,the wires in question attached to the starter solenoid.
The 2 large wires are tied together and fused at 30 amp.
Solder these connections Please.
Attach the fuse direct to the battery cable.
This eliminates the Dog Bone type fuse built into the solenoid.

The 2 small wires operate the solenoid.
With the big red ones removed they are the only ones needed to make it click.Just reconnect them direct to the pins on the solenoid and throw away the burnt up plug.
Here's a post about the wiring I do to my bikes to eliminate these problems.viewtopic.php?f=5&t=12522
Post if you have any questions.
