Alrighty, I started my wiring - and here's what I've got so far... I've identified and taped all my proper wires, I've stripped and tinned my phone wire. I temp soldered my power and ground line to the proper sources on my car ( cig lighter ). My MPGuino still works great on USB power, well, when I plug in my phone wire which is grounded and has power nothing happens...
I've checked resistance between the power prong on the RJ11 Receptacle and D1, and checks good (00.1) ohms.. I've checked power coming in from the temp solder point to the prong on the male jack.. 12.2 v. Good coming across the wire, good going to D1, but no power to my MPGuino...
Suggestions would be welcome!
