I was plowing snow In my Polaris Xplorer 400 I switched to 2 wheel drive to do some donuts I saw some smoke coming from my front headlight pod I thought my headlight bulb blew but it didn't. I took the pod off and nothing seemed burnt. Now my 4wd and my reverse speed limiter won't work. Also I was using a battery that wouldn't hold a charge. Can someone please help me? Thanks, He bus.

 

If you already had battery problems(not holding a charge because of age or a regulator/rectifier problem) it's possible you had a surge that could have burnt up the reverse limiter module.Voltage has to go somewhere if the battery wont take it! Remove the limiter along with the regulator and check the back side for any melted spots. Limiter is not that important to replace,you really can just remove it and have full power in reverse at all times without having to push the over ride button. Have the battery load tested,replace if needed,then see if it's charging 14-14.5 volts back to the battery while running. If not, it's usually a reg/rectifier problem.Plus they can over charge which could cause a surge also. Here's a link to cheap replacements if needed. Polaris ATV Rectifier Regulator
Plus check the thin awd wiring and connectors under the front panel that go to the struts.Plus you have to have 12 volts for the awd to even work. OPT

 

Thanks for info opt....I haven't had s chance to work on it yet....If the limiter is blow in and I disconnect it should my awd work again

 

If you have a good battery(12 volts) and you didn't tear something up in the front wheel drive Just disconnect the black wire on the limiter,you really don't have to remove it. Plus don't forget to check out the charging system. OPT
