MC54B Died, battery smoking, battery wires hot!

[Smoak-Eater]

Hey all,

Been a while since I posted, been a tough couple of months for me! Back in July I rode in a poker run, less than 150 miles.. On the last part of the ride we ran through some areas of recent rain and the roads were wet. My bike bogged down then died. I assumed I sucked some water up into the custom intake, so let it sit a few minutes and she cranked back up.

About 15 miles later she just died at speed (55 mph or so) I had smoke rolling out from under the seat and no electrical power to anything. so I got it to the side of the road and opened up the seat to find the battery smoking and the battery cables were super hot.

We got it on a truck and hauled it home, and the next day I got down with a knee problem. (I am a triple amputee with prosthetic legs) The knee kept me down for a few months so I didn't fool with the bike.

Now I am back to normal and wanted to look into the bike issue. Could the road water I rode through shorted something out, or is that coincidence?

I have to assume whatever counts for an alternator/gennie on this bike screwed up, but I know jack about the electrical systems on these.

Any thoughts or suggestions?

Thanks!

check out the rectifier/regulator it should be under the front cowling mounted to the frame.

You have a massive short somewhere.

Check those lead wires going into your fuse box and ground wires

This bike doesn't have a fuse box. I assumed it was a short from the water, or a goof in the charging apparatus of the bike.. The rectifier mentioned above, maybe?

Then you must have a fues next to battery and one in the relay. I run mine in rain all the time, never had a problem, I thinking a short or loose wire somewhere. I would trace those wires from the battery back to the r/r and check fuse in the relay.

Definitely check the condition of your ground wires and positive wires running to and from your battery. I found that the engine had melted off the rubber casing of my main ground wire that is directly connected to the battery. That definitely caused a short for me. Even the smallest amount of copper wire showing can cause a lot of problems.
