Had all my lights blow out on my 2000 sportsman 500. Even the control switch lights went out but not the speedometer. I have a voltage regulator under the seat in the storage container with the tools. It was for the winch and spotlight I added but later on removed the winch and light. Did a continuity test on all the lights and there is a complete circuit for all of them. I don’t know what else to do from here, is it the control switches or the after market voltage regulator
