Dean,
Just starting a 3 day trip, but will look at the e-manual while gone, and then at my schematic when I get back, to see if I can find a terminal layout.
I replaced the battery, and it was no big deal...however, I did have just enough service loop in the DPU wires to get to the cover and replace the battery component (it plugs into the circuit board). Saved a lot of hassle disconnecting all those wires, but was a bit of time on the head, with legs sticking out of the canopy!
Not sure if the DPU has markings, or if you have to count terminals. Will also look at my neighbor's spare DPU, and let ya know what I find out! Any ideas Larry?
Cheers,
Bob
