GL1000 Electrical Shutdown

Postby bobbythehunter » Tue Oct 04, 2011 8:01 pm



Hi Folks

Haven't posted because I haven't been riding. Took bike for a spin the other night, got 5 miles from house and I had a total electrical shutdown. Stood there and stared at the bike for a few minutes then opened the tank cover and side covers and looked at the stuff for a few minutes, then took off the side cover and looked at the battery and noticed a totally melted down fuse holder and fuse. Got the bike towed home and just checked the parts schematics and although the fuse and holder i burned (30A) didn't look like that on the diagram I believe i burned up the "Box Assy Mainfuse (Daiichi)" part # 38250-371-153. looks like this part may have been consrtructed as it had an inline 30A two plug fuse like you see in todays autos.

How bad is this? Can these parts still be obtained ?
Thanks for any help you can provide.
Bobby

A lot of us have us have replaced the dogbone main fuse with an automotive 30Amp fuse holder. Available at any auto parts store. I would be concerned about why the holder melted. You should do some electrical testing for an overload condition that is pulling too many amps for the circuit, or more likely, loose connectors that can cause the wiring or connectors to over heat.

If it was drawing over 30 amps, and it had a 30 amp fuse in it, then the fuse would have blown. So assuming it did had a 30 amp fuse in it, the problem is either:

- loose connections of the fuse holder that overheated
- (more likely) previous owner installed fuse holder not rated for 30 amps

Either way, it's an easy fix. Replace it with a fuse holder rated for 30 amps, put a new 30 amp fuse in, and you're on your way.

I found the main wire to be worn thru next to the frame above the condensor or gas on/off valve. I would turn it on to start, hit the button and the panel lights would dim and not turn over. Just FYI.

Generally,I've found that the wire color on the fuseholder indicates it's capacity.Black wired ones are used for up to 10 amp,red up to 20 amp and orange are 30 amp.
Verify that first,keep the wires as short as possible,solder the wires if you can.
I actually cut the 2 red wires off the plug and solder the fuse holder to them,the other end goes to the starter terminal off the battery.

Also,the charging system is rated for just under 30 amp MAX.The bikes draw about 10-12 amp,so it leaves right around 15 amp that can flow through the fuse to the battery.

Generally on a good system,I've seen 15 amp for 4 minutes then drop off to near 3 amp through the fuse.

thanks all for the input. the positive connector on the battery had loosened, could this be the culprit?
thanks

Hello , Maybe the problem is loose connections of the fuse holder that overheated. Either way, it's an easy fix. Replace it with a fuse holder rated for 30 amps, put a new 30 amp fuse in, and you're on your way.
