Help Needed electrical issues
I have a 1999 7.3L with several electrical problems. The problems are no speedometer, no turn signals, when the RPMs increase the voltage from the ALT increase up about 18V, if the MAP sensor is plugged in and the truck is in gear the RPMs only increase to 900 if you unplug it the truck revs...- John Johnson 69
