As far as hot ballast is normal. Do NOT leave the key on for long without the car running. Hard on the ballast, coil, and ignition box. There is a connector at one end of the ballast with a jumper ---2 of the pins are jumpered to gether. With key in "run" you should have "same as battery" there. The coil normally sees somewhere between 6 and 10V when sitting stopped "key in run"
