Got a little technical question here. I haven't looked at it closely yet but my LED came on very erratic this morning. Could not find anything wrong. No running problems. New pressure sense switch installed Sunday. No shorts in the wire. All clean. LED came on after about 40 miles of driving. I was wondering if the LED is actually driven by a transistor or some other type of indicator driver or is the LED hooked up to +12 through a resistor and the other lead goes directly to the pressure sensor switch? Anyone know off the top of their head? William |
