What you want to do is see what it does under less load. Say, turn on the headlights, see if/ how far it moves, with engine stopped. Turn on the key, turn on heater blower, step on brakes. "I bet" you can't even see the needle move.
I did that and it acted like it should! Even dumps down a bit when cranking the engine. I hear what your saying and I'm surprised as well! But like I said I'm not done tearing the rats nest out from under the dash. Its a total **** show, bunch of after market gauges and lights
