Hey Jeff, I've had your DSATX for a long while now without any problems. Now, whenever I supply ACC the red light goes on for a couple of seconds, then goes into a fault - 5 blinks. I measured 11.8 volts at +VIN and at ACC. I have pulled the fuse to reset it numerous times and got the same results.
I was going to hook my brainstem up but for the life of me I can't find it anywhere!
I noticed I have a firmware version D894805. Can this be the problem that it has the older firmware that needs updated?
Thanks for your help!
