I can't for the life of me diagnose this problem. My only conclusion is that some how the PSU was damaged in transit. Well lets get to the nuts and bolts of this...I'm going to try my best to you guys with enough details about my setup as possible. PLEASE bare with me.
Im running 8 guage with a Mini fuse holder 6" from the battery into fused distribution block 10 amp fuse. I then connected the two red wires from the p2140 into one of the inputs on the block. Meter reads around 12v at block
For whatever reason I can't find the acc wire in the wiring harness for the headunit. I literally tried everything multi-meter and 12v test light. I did however find a wire in the harness for the climate controls that turns the test light on and off with the ignition. It reads around 7v with meter
The jumpers are set as follows:
jp4 config 2
jp5 mac mini intel
(Firmware has been updated downgraded & everything in between)
FAN REFUSES to spin with ignition on
I also tried connecting the yellow acc wire to a constant 12v power source still nothing.
Distribution block hooked up to power wire from battery
yellow acc wire hooked up the harness from climate controls
(in the background you can see my ground wires)
test lead from meter reading 11v on j2. All the output pins read about the same. One should read 18.5v for mini and the other 12v for the screen, but they don't & i kno better than to connect anything w/o proper voltage
me measuring voltage on fan which is .04...I'm not genius but i doubt that should be the case. Shouldnt it read 12v?
Listen guys i really appreciate any help, seriously this is very frustrating
Tried it, no dice. I even tried the old firmware. Current flows through the carnetix, but the fan is dead and the readings on J2 are not what they're suppose to be. I think its a lost cause, any other possibilities? ANYONE?
Just thought i'd report the fix for anyone else experiencing a similar problem. The problem was with jp4. For some reason the p2140 wouldn't start on config 2 so i switched it to config 1 even though the current limit of 7.5a wasnt being exceeded since there was nothing connected to j2.
