Howard your writeup in #15 was excellent and spot on.

When I started looking into the wiring I found one wire (red 12G) connected to the circuit breaker with it’s output being connected to the input of the relay (terminal #1) 12G . On the relay there were two wires (a red 12G and black 14G) connected to terminal #2 (output from relay) and two wires on terminal 3 (both red a 12G and 14G).

On the relay the red 12G on terminal #2 went to the power seats. On terminal #2 haven’t figured out what the 14G black wire is for yet). On terminal #3 the 14G wire (that melted) went to the ACC on the ignition switch and the red 12G went to power the windows, which explains why the 14 g wire failed. The red 12G should have been on terminal #2 and not #3.

I think the 40A circuit breaker and relay setup was Packard engineer’s work around for not putting another possible 40A draw on an already over taxed ign. Switch. I think they should have put two places in the fuse box for the PS and PW with 20A each.
