Ignition switch failures.

I found my stock system pegged at maximum amps for the alternator when running all the stock accessories.

A local electrical shop confirmed my suspicions by doing the same current draw check on the wiring harness. He snickered in a comment to me, " Why did GM do that?"

I am thinking the AC relay circuit would also solve some of the problems as it takes the high fan current load away from the dash harness I believe.
