The proving grounds is in milford michigan, hes been there for about 22 years so I trust that he knows what hes doing. I will test the purple wire first and see what happens. I did notice that when I turn the key to the on position there is a clicking sound kinda like a relay and that is when it bounces. Could it be something to do with that. Maybecthe guy I got it from wired something wrong and taped into that wire to power something?
