[QUOTE="machoheadgames, post: 431269, member: 18789"] Chalk me up as another hater of scotchloks/t-taps. Junk that only cause problems. If you unplug the oil sending unit, does the the gauge peg to 80? Definitely sounds like you have some ground issues with both gauges messing up when headlights go on. Especially since one goes up and the other goes down. They work opposite of each other, oil pressure goes down when it sees less resistance to ground, and water temp goes up when it sees less resistance to ground. Since they’re both going in opposite directions with headlights on, they must be each seeing less resistance to ground when you are turning the headlights on. Not sure why. [/QUOTE]
