No Electrical Power
« on: July 11, 2021, 06:17:05 PM »
Did not ride that day just took the ATV out of the garage to inspect possible locations to install a rear mounted winch.  I did not disconnected or disassembled anything at all.  Took it back to the garage and park it in reverse.  I stopped and everything just died.  ATV vas still in reverse gear and I lost all power without turning the ignition key to the off position or switching the fuel pump off (kill switch).  The dashboard turned off, the engine stoped and now I cannot get any electric power anywhere.  When turning the ignition key to the on position the dashboard does not come light up, I have no lights, no turning signals, no horn, no fuel pump, no hazard lights.  The only thing that works is the winch which is wired directly from factory to the positive and negative terminals of the battery and also the brake light when I apply the hand and the foot brake does work.  Following the red cable coming out of the battery I only found one 30 amp fuse on the ignition relay that is good, also tested the started relay and it all seems to be in working order, then the wire harness goes under the front fender and it is impossible to follow without taking the machine appart.  There is another 40 amp fuse but it is connected to some wire harness on the negative terminal and that is also ok.  Checked all the 9 relays (lights, fan, and starter etc) on the from of the machine and they are all securely connected.   

 Is there anything like a main fuse on this machines?  if there is, where is it located?

What else can I check?

Did you ever get a response? I am having the same problem with my 400. I found the fuse box under the front hood but is there a main fuse closer to the battery?

Yes, there should be a 30amp...and CFM has had a lot of issues with the main fuse holder itself having bad connections inside it. Bad crimp connections or something.

One of the main fuses under the hood was tripped so I replace it, got power again and was able to start the atv.   Not sure what happened but I lost the ability to engage 4WD or lock the front diff.  Had to take the quad to the shop where repairs where cover under warranty but they never told me what was replaced.
