I went through and re-did 10 years worth of wiring mess in the bilge area. I had 4s repower in may of last year. Nearly all of the rewiring was moving accessory wires to not be a giant birds nest and relocating my power pole pumps.
after i had everything hooked back up, i was not getting ignition signal to power on my main relay bus and no tilt trim (no beep or anything when turning the key either, didn't hear fuel pump). I've disconnected everything from the battery and completely isolated only the clean power connection and main battery +/- wires to my battery at this point.
I keep reading 21-24v when reading the voltage on the clean power terminal. I can even disconnect it completely and it will show the same voltage between the 2 disconnected wires at 20+ volts. From the disconnected ground of the clean power to the + bat terminal, it will read 12v (clean power still disconnected).
With only main terminals and clean power wired up, i checked voltage at my ignition between the +/- pins and it was showing 24~v there also.
I have since disconnected the large round controls connector also and same results (not to ign obviously) but no tilt/trim using the trim switch on the chasis.
From my understanding of the clean power harness's purpose, i don't think i should be seeing voltage (let alone 24v) when its disconnected. Not sure where to look from here. I will call my dealer, but looking for any insight as the motor is currently trimmed down and i can't tow it anywhere the way it sits until i at least get the trim working.
I've also checked that i have 12v at the main power lugs on the front drivers side under the cowling and that all the fuses on the port side front are good. I read 12v on the fuel system fuse, the rest 0.
