Ok, so at idle I am getting 12.7 - 13.3 volts, when rev'd to 1500 rpm I am around 13.9 - 14.0 volts. I am planning to call Slee to get their headlight harness to see if that helps but now I am more worried about a surge knocking out something else in the system. So now my question is: could this be a problem with the alternator or voltage regulator there-on? I know that most Toyota stuff is switched on the negative side so could it be the result of a bad ground somewhere, and if so where is a good place to start looking. When it bumps up that high, the high beams work again momentarily until the voltage drops off. I will try to get a picture of the "surge" voltage but for reference it is near the line just below the "18V" reading, not the fat one, the skinny one that is actually the second from the top. This is how the gauge reads most of the time. So tonight I notice that the voltage gauge in the dash would rise and fall with the surges.

Fast forward a few months and I notice that the low beams would brighten and dim at random and when they would brighten up that all of a sudden the high beams would work. So my dash lights had started to fad when at a stop. Ok so I have been chasing a gremlin that has plagued my head lights and dash lights.īackstory: Several months ago my high beams "stopped" working when switched to high, the flash still worked but no regular highs.
