i am degreasing my motor to do a timming chain so i cleand it by spraying it down with the heavy duty degreaser and water . i ran the truck and it drove fine. came back an hour later drove it and now the voltage is on the high side at idle. when it revs out it will go to 18v the battery light and brake! light will light up.
now, if i turn on my a/c and headlights the voltage will still climb with revs but the batt!! will not light up.
Im guessing i smoked the voltage regulator, is the regulator internal or external on these 1985 year?
