my ongoing struggle

[seanbumalmighty]

Hey long time no post. My car has been in storage all winte while i gather parts. I just got my Pettit limited ecu and installed that and two boost gauges with a buddy of mine. We started the car and took it for a ride to set the boost. The gauge i had wasnt working right so we brought the car back to his shop to swap out the boost gauge. On our was to the shop it started to idle very low between 200 and 500 at standstill. Once at the shop with the hood open we realized that when the coolong fans went on the engine would idle as mentioned 200-500 rough idle. I went to turn the car around to put it in a spot and it died. It would not start , i checked the plugs to see if it was flooded but the plugs were dry. The plugs were black as night but i dont think that would cause the idle issues under load. It could be the altenator but i cant test it since it wont start.also when the car died the fog lights cam on and wouldnt go off! Im thinking bad grounds? Altenator? Anyone experience this befor?
