Subject: Thanks for the additional insight. Actually ended up replacing Author: 740isport : 4432 posts Posted on: 2009-12-01 20:29:58

both relays, Main and FP. Tried just the main, but the problem persisted, then tried just the FP and the problem was still there. Replaced both and the problem went away. The condition of these two relays was that they looked close to original installation (oxidation on the case and such) and I think they were just worn out. But the replacement of both has worked perfectly.

Now I am just working on why my battery is dead after only 4 or 5 days of not driving. Only power I see being used is the anti-theft blinking light on the stereo. Any thoughts?
