For a 150cc quad I would guess that it would need something in the neighborhood of ten amps.



Five pin voltage regulators do have heat sink fins on them. Do a google search for "atv 5 pin regulators" and thumb through the pictures to see if anything looks like your regulator.

Yes, unplug it and see if the fuse stops blowing (after you look carefully at the fuse and report all the writing on the fuse ends).

My thinking is like this: If you have the right value fuse installed (something like 10 amps), then to blow this fuse you would have to draw more then 10 amps. Ten amps at 12 volts = 120 watts of power. That's a lot. If you have a single component failure somewhere that is drawing 10 amps it will be smoking and emitting flames. You didn't report that.

Therefore whatever is dissipating that 120 watts of power must be physically big so that it can take that kind of power and not get hot instantly. I'm thinking that if the voltage regulator rectifier diodes inside were shorted, everytime you turn on the ignition the battery would be connected to the stator windings. They're big and would draw a lot of current - maybe and maybe not enough to blow the fuse. But if you applied an additional load (lights, starter solenoid, etc) it would certainly blow the fuse.

Your fuse doesn't blow instantly, and all the time when you turn on the ignition. That eliminates direct shorts to ground (such as a power wire that is pinched under a screw head.) If this were the case the fuse would go off like a camera flash bulb. Instantly and every time.

And once again, if you are putting in the wrong fuse (too low a value) then the fuse should blow. Make sure your fuse is around 10 amps. Whatever you do, *DO NOT* install a big fuse like 30 amps to see what will happen. You might end up with a melted wiring harness and maybe start a fire besides.

OKay so i unplugged the regulator and the fuse didn't blow. I turned the key off then back on and the fuse still didnt blow then i was running my ATV then i tried putting the lights on they went on for 1 second then the fuse broke so for now on what should i do ? Never Turn the lights on i unplugged them and now what do i do with the regulator keep it unplugged ?

That is *way* too low a value. Your headlights draw 3 to 4 amps, the starter solenoid draws 3 amps all by itself, and of course the brakes light must be on to statisfy the safety interlock - that's adding another amp making it four amps total draw through a 2 amp fuse. No wonder your fuse is blowing . Change that fuse to 10 amps (that's a fairly typical value for a 150cc machine). Take your 2 amp fuse down to any auto parts store, show it to them and say you want one just like it only rated at 10 amps instead of two.

Then plug your regulator back in and see if your problems are now all gone. That might be all you need to do.

If after changing the fuse it still blows then we can start again fresh since we have at least one of the problems out of the way...
