Well I just removed the tcu from mine. Charging the battery up now for testing.

If it isn't down any tomorrow problem solved hopefully.

If I wasn't going to switch to an aftermarket radio anyway I would permanently fix the tcu issue by rewiring its power feed to an ignition wire in place of live all the time.

Come to think of it I may do that anyway. Kind of sounds like fun and it will be a bit before the new radio gets here anyways.

Well lets see how this test goes first.
