500 NO POWER, BLOWING MAIN FUSE [SOLVED]

500 NO POWER, BLOWING MAIN FUSE [SOLVED]

PostAuthor: rchawaii » Mon Oct 28, 2019 8:06 pm

Background: My bike has been sitting for some time. I had installed a 250 headlight on it, but recently replaced it with the original 500 headlight.

I thought maybe it was the key witch, I took it apart and put the three wires together, as soon as I give battery, blows main fuse.
Went through the wiring diagram (for the 500) and the headlight harness wires all look correct. I do not see a short, and they all look like they are connected properly. I dont see anything in the bucket wrong.

Because the old tube fuse connectors are hard to find, I replaced the fuse block with blade fuse block. 20-main, 10- 10 - 10 per original. (Was blowing before I changed the fuse block anyway)

So, the ignition is fine, the wires in the bucket seem all good

My stand switch was gone and it it wired together )The two wires connected and taped)

Battery is new.

Checked the ground but it looks like it is mounted to the bottom of the crank case. I couldnt remove the cover over it tonight but it appears good.

What else should I be looking for?

R/R I dont know where it is, but I hear it mentioned a lot. If I need to check it, how? Im not very good with a multimeter, but I have one.

Thanks.

When my r/r fried it would blow the fuse. On my xv1100 its under the left passenger foot peg. The reason its there is because the r/r gets hot and air flow down there is cooler.

When it blew I called a tow truck, if I only knew I could have simply unplugged the R/r and I could of rode home on battery power.

Close, but the 500 being the odd ball of the Virago line, it is the only one to have the R/R mounted behind the right side passenger foot rest.

I'll give it a check. Thanks Jake. I have also read that it could be in the left hand controls, true?

Not a regulator/rectifier.

Im sorry, thats not what I meant.

I mean I read that a problem with popping the main fuse could be tied to the left hand controls? Just trying to eliminate problem areas when I go to look at it again this afternoon.

Thanks sir.

If you are blowing the main fuse, you have a direct short to ground somewhere. When does it happen? As soon as you connect the battery or as soon as you turn on the ignition? The main fuse goes directly to the R/R and to the ignition switch. All other places require the ignition switch to be on.

I believe that you mean the stator ( generator ), if so, then yes, it’s under the left side engine cover.

If you don’t have the Yamaha Factory Service Manual for the XV500, here is the link download/file.php?id=31287.

The testing procedures are there.

I was concerned it was the ignition switch. So I removed the switch and just connected all three wires together. As soon as I touch battery, the Main Fuse Blows. [Switch on]

Tying all three wires together just eliminates the physical ignition switch. The Br wire goes to the R/r and the ignition fuse, the L wire goes to the tail and stop lights thru another fuse. If you are not blowing any of the other fuses, and the r/r checks out, then your short is possibly in the fuse block.
The R/R should have a connector close to it, unplug it and then test. If that test does not blow the fuse, then the r/r is most likely bad.

Thanks man. I did just that tonight. Unplugged the r/r and tested it, When I connected power, got power. so I thought it was the Regulator/Rectifier. But plugged it back in and tested and it worked. I don't know what it was, but its solved. I'm going to go through the RR and double check it and all connections. Something made it happen

I appreciate it very much everyone! !! It was good to see lights, even if they're all not working as should. (Another thread for another day lol)

intermittent error is not solved. I'd start looking for a bare spot in inulation. Stick with whatever wires effect the main fuse. Bend, jiggle, push wires to get reaction. You can hook up a suspect wire to buzzer, one leg to power then to wire, one to frame. The bare conductor may briefly touch but you'll hear it.

Imagine how much grief you save not walking.

Just to update this and close it out. Re-checking connections, I had a short near the R/R and wire off of the harness that was hitting the frame. Once I removed the plastics and moved it, it stopped blowing the fuse. It has been corrected.This has been resolved.
