Again, nothing has changed in the connections from a condition where it was working properly for 3 years. I've checked the connections at the battery, the PD and ohmed the cables. The PD is located about 2' from the batterys with #4 cable. The fact that the WFCO gives proper charge readings on the Trimetric would seem to indicate that all connections are correct.
Another note is that the fan on the PD never moves when the pendant switches it to 14.4 volts which would indicate that something "popped" in the PD and no output.
