I didn't no if electrical was drivetrain, but it fits in the best. Alright, i noticed my head lights were burning out too often, so i replaced the voltage regulator. Got a "Universal" one. I've been researching a bit and i'm not sure if its true but people say universal ones won't work long and you need the OEM..the universal one is blowing the lights already. :dunno:

what sled. seems a lot of people do have an issue with aftermarket voltage regulators

 

[smallengineguy]

My aftermarket ones have worked well. It may be another problem.

Check for grounding out/shorts in the harness, particularly where it passes by the exhaust.

its a 91 polaris sport 440. My friend said its cause of my neons. he had a sled with underglow doin the same thing. but that didn't make sense to me cause i used the handwarmer wires to wire my neons..wouldn't it put out the same amount of power to the neons it was to the lights?

 

[smallengineguy]

It should. If it were drawing too much power, it would burn out the lighting coil on the stator, not the regulator.

The neons are likely DC and without a battery for electric start the sled is putting out AC!

 

[MarcusSport440]

well i took the neons off. gonna try a new headlight and see what happens.

still blew the headlight once i put it on high beam. i put it in. reved it up on low beam, then switched it to high and it blew. How would i check for shorts in the harness?
