1982 850GL Electrical problem

main fuse

supply more info ,like when you turn key,could be short in key switch or when you hit starter,could be relay or shorted starter etc,etc.

We need more info, IF It runs ? I would disconnect the stator & the reg/rect run it does it still blow the fuse ??

The bike will start, run for about a minute and then the fuse blows.

There are any number of reasons for the fuse to blow, all of them related to an overloaded circuit, but the first thing I would do is ensure the battery was charged, then pull the connectors off the Regulator/Rectifier.

Do this with the ignition switch OFF.

The bike will still start and run, but cannot deliver a charge to the battery, so you will be running entirely on battery power.

If there is still a blown fuse then it will be necessary to check out the circuit itself. Connectors are the next thing to check. Dirty connectors are a common problem on these bikes, and the dirt causes resistance. Enough dirt/resistance in there will make the fuse quit. Loose connections cause arcing, and this can blow a fuse.


An obvious thing to do is look for loose wires that cause a short.

Thank you Ron. Where are the connectors? Under the gas tank?

I am not certain of the location on your bike, but the R/R is always located close to the battery, and probably very close to the fuse box as well.

You should have a solid plastic connector with a catch on it. Since all the wires are in the connector, they all disconnect at the same time.

If you should find that you later need to do a full stator/R/R check, note that the wires coming from the stator are usually of one colour, (yellow) and are interchangeable.
