I don't think it would be in the lighting circuit, because if there was a short in the lighting circuit, it would blow the light fuse, too. I think the problem would have to be from the point where it leaves the ignition fuse onward. Notice that after leaving the ignition fuse, the wire runs to the ECU and to the ICU and then on to the carb heater and the handlebar switch. I would try unplugging the ECU and the ICU and the carb heater, one at a time and see if the fuse blows. My money is on the carb heater being the problem.

from what i'm seeing..the 10 amp and 15 amp fuses are linked together comming from the key switch..if there is any kinda short between the key switch and lights..the first fuses that blows will be the smaller fuse..correct ?. and it would help alot if we knew what model he has..elec or manual shift..lol..both models have different wires and fuses..lol.

I was looking at the wiring diagram for the ES models. If this is a foot shift model, the wiring leaves the ignition fuse and passes through the ICM and handlebar switch. It doesn't pass through the carb heater on the foot shift models. Also, the foot shift model doesn't have an ECU. There may be a problem in the handlebar switch or in the wiring, itself.

Yeah, I agree, we need to know the model, because the wiring is different.

i totally agree...i wish memebers would read the post about posting a problem..this was put thier for a reason..we can't help them if we don't have all the correct info !..lol..between the elec shift and manual shift..they changed alot.

At any rate, I would unplug the components from those two circuits, one at a time to see if the fuse stops blowing. I would unplug the ICU, the ECU (ES model), and the carb heater, one at a time. I would also pull the neutral and reverse light bulbs and check the sockets. On the foot shift model, the carb heater is on the lighting circuit, so it could still be the problem. Knowing the model would be a big help here.

yep..i would start with the lights..maybe one of the sockets got water to the bulb ?..who knows !..we at least gave him a run down on what and where to check..and your right..knowing the model helps !..lmfao.

hi

if it is a 350 rancher manual shift i had same problem. it was voltage regulator on frame by back wheel un plug it then see if you fuse blows if not then it is the regulator they short inside and since they are screwed to frame they short to ground and blow main fuse. mine is 2001 350 rancher fm.

The OP's main fuse isn't blowing though, it's the ignition fuse. If the main fuse was blowing, then I would agree that it is a shorted regulator/rectifier. And welcome to the forums.
