Fuse Nightmare!

[portugeezer]

I have been trying to put my GL1000 back together. It's going very slowly. I have run into a lot of issuses. I finally got the bars on and everything hooked up. I had all sorts of problems. One has me stumped. I start the bike and it runs for about exactly three minutes every time then just shuts off. The bottom fuse is blown! I replace the fuse the bike starts back up but three minutes later same thing! I find no obvious shorts and can't imagine why it takes three minutes to blow! This is making me crazy!!!

Explain which fuse it is please.One of the glass fuses or the main fuse.
A bad regulator could cause it (main fuse blown),unplug it and test again

[portugeezer]

The bottom fuse in the fuse panel is glass it works the horn and tailight

[virgilmobile]

It dosen't make sense...Even if the fuse blows the ignition should still be OK.
That fuse exits the fuse box on a white/green wire and applies avaiable power to the horn,buzzer,front and rear stop switches and the winker(flasher relay).

Iffin I was you....I'd remove the fuse temporarly and see if the others have switched volts with the key,It comes in the black wire and feeds the 15 and the 5 amp fuse.

The mose common problem I've heard of is connecting wires togeather.
It's easy to hook a light green wire to a green connector.There not the same and age can change the look of the color code.Pull back some covering to expose the true color.
Fortunatly Honda made the bikes to fit color for color.
It would be easy to miss put one and put it in the wrong plug.

Just saying,ya know....It did happen to me....Under the fork weight cluster....I had a light green wire pluged into a dark green wire....Oops...grounded that circuit and blew a fuse.

Ok, I'm having a slow work day so I went back outside and thought about clues instead of doing what I always do and start messing around with stuff. Since I put the bars on each time I switched on the key I had the tiniest little bit of horn noise. The fuse says horn. So I disconnected my air horns and took the horn of my parts bike and VIOLA! Everything works! Sometimes I wish I was a little bit smarter but then I may not be dumb enough to never quit the fight!

[portugeezer]

I agree that a blown horn and tailight fuse shouldn't shut down my ignition but it did! Fire does weird things! I also have a lot of white smoke now until the bike is warm so I'm thinking head gaskets this summer!

[portugeezer]

The color code thing was a total nightmare Virgil because the wires are all covered in soot. I had to wipe each one off with oil to see what color they were

[virgilmobile]

I don't envy the task your faced with,but i'll help if I can.

Get a full color blow-up of the schematic- about 2' x 3'- and hang it on the wall right across from the toilet (or somewhere real prominent like that!) At a time like yours it would be really super to have it memorized

I scanned the schematic for my 82 1100, blew it up across four pages, and taped them together on the back of my office door. Works well for quick reference.

You're so much more 'sane' than am I myself!- But this is actually more of what I had in mind!

[portugeezer]

When I got my bike it mostly need cosmetics or so I thought! I soon realized that I only sometimes had signals among other problems. I took the sidecovers off the false tank. The wires were a nightmare of splices. Most of the bike had been rewired by using those blue splicers. I have pieces of harness that have been replaced. When I replaced everything from the handlebars a lot of things were corrected. The bike is very close to factory wiring now! I went through most of it. I found several wires that went nowhere! I assume that was from accessories that were once on the bike.

[Fred Camper]

Good idea to remove the wires that go no where lol. You know the parts that belong, and extra wires mean extra trouble ahead. Good that you solved your fuse issue.

Do you have a Dyna ignition??? If so,the reason your bike dies when the fuse is blown is that is where Dyna says to tap in for the 12v to run the ignition. No power,no ignition!

[portugeezer]

Yes it is in fact a Dyna!

[Fred Camper]

Geezer, I had trouble with my Dyna until I moved it to a relay off the ignition circuit. I used a relay to get it full battery power all the time as my ignition voltage was typically down 1V. Something to consider if you still have issues.
