I've had typical cluster issues intermittently shutting off the gauges, windows, etc for a while now.
Yesterday dropped the boat in the water and couldn't get my windows up. So I threw a little man-fit and beat the hell out of the dash and still didn't help. So backed down the launch to pull boat back out, truck went into what I'm guessing is limp mode: hard shifts, reverse works great, no power in fwd gears, blowing smoke everywhere, battery light came on. So whacked it a few more times and turned truck off and on a few times and was able to pull boat out and drive home. Battery light flashed a few times while under load.
Today on way to work, battery light came again, programmer showed battery at 11-11.6V and FICM at 10.5V
Truck ran fine. Got to work, pulled up the battery voltage on the cluster with truck off showed 14.2, started truck and same, 14.2, programmer shows 11.5 and battery lights is on.
Is there control circuitry in the cluster for the charging system too?
I may have just knocked something loose. Connections are all tight and I have an aftermarket high output alternator.
