J.RM7030 (Product No. 921890401) and RM7732 NOTE: The PAL tester will allow for proper testing of the integrity of the upper and lower circuit boards. PAL is available from your Dometic parts distributor.

NOTE: Each of the following tests should be done according to pin locations. The wire colors may vary.

With main ON/OFF switch on display panel in OFF position:

Check for DC voltage at Plug 1, Terminal 4 and terminal 5 negative (–) DC on the lower circuit board. If no voltage, then check fuse condition. Replace if blown. Check for DC voltage between J4 and J10 terminals on the lower circuit board. If fuse is good and there is battery voltage at J4, remove and replace lower circuit board.

Next, check for DC voltage at the upper circuit board between terminal 4 (orange or white wire) and terminal

3(black wire) which is negative (–) DC. If no voltage, and your previous check proved voltage at the lower circuit board between these wires, replace the cable assembly. If DC volts are present, proceed to the next check.
