electrical problem

Postby hansmax » Mon Jun 27, 2016 1:26 pm

I have a 1985 Honda Goldwing Iterate, GL 1200
My Bike would just stop running when it got warm then start again when it cooled off.
While trouble shooting it, the whole system went dark, no electric power.
I tested the fuses and all seem ok.
While checking fuses the power seemed to come on but when I try to start it I hear what sounds like a electrical arc.
The lights start to dim then go dark.
At one point the positive terminal started getting hot but didn't blow a fuse.
I am lost at this point.
Any help appreciated .

Remove both battery cables.Clean till shiny...including the battery posts.Secure them very tightly.
Open the trap door on the starter solenoid.Remove the dogbone fuse.Clean the pads.Replace the fuse with the spare in the door.Inspect the 3 yellow wire plug for heat damage and repair as necessary.

This : << the whole system went dark, no electric power>> implies a master fuse ... the #$%@&^ dogbone fuse , most likely ..

These crazy pieces of Honda Bad engineering live in the open air , often crack , but not break, and cause just the sort of intermittent problems you describe :
no power when hot ( and crack opens up) and back again when they cool down .

If cleaning the battery, and the master ground points,( on the braided cable ) and replacing the dogbone fuse gets you back on the road ...

then ... go to possibly a marine supply house, get a waterproof 40 amp in line blade fuse holder, with as big wire as they have ( 12 ga ?? ) .

With a little searching , you might even find one with the brass eyelets already pressed on ...
and you can just fasten it with the same screws used to hold the dogbone fuse .

Cutting out and hard soldering and shrink wrapping the three yellow wire stator harness connector is a good second step .....

but I doubt if thats causing your intermittent electrical gremlin ..

Good Luck

Thanks for the info.
I have done a little more testing and found out that if I poke around the wiring around the battery the dash lights come on at least the center and left ones not tail lights.
I hit the starter button and all goes dark again, also the positive terminal starts to heat up very fast, very hot.
May be a very bad sign.
I will keep looking but loosing hope...
