Swapped a m37x engine to my g37x coupe. went smooth so far no codes but I have battery and brake light on... Radio turns on fine but has no sound. running 12.4 volts off and 15.5 volts on with just radio.. seems overcharging. Any tips or help?
Mak sure the main batt ground cable is going through the induction sensor ring.
and any extra grounding cables aren't jumping aroiar said sensor.
make sure battery is up to snuff.
And finally, the FSM outlines the full charging system check

do you have a picture of this sensor ring? I also forgot to note that my inktakes are not setup just mags plugged and my cats are my only exhuast on there and plugged in.. could that also be my high voltage?
Above pic is incorrect- that is the positive cable/fusible link unit.
Ironically, I just had to replace my negative cable last week due to the clamp stretching and not tightening on the battery post and coming loose. Pics are of the cable and the current sensor from a 2008 Coupe:
Hope this helps...

Hmu interesting I'll have to take a look at that. I'm looking at FSM now and I don't recognize those ground at all. I dont think the negative terminal was line was ever touched because it stayed in car during swap but I'll check anyway. Thanks guys.

Maybe, but it is possible that the wiring connector was disconnected when the old engine came out. Being that everything was working fine before you swapped the engines, the issue you have now is likely wiring-related. Besides, it never hurts to double check all of the wiring and connectors- make sure everything is fully connected and that no harnesses/wires are cut or pinched.

Seems like issue fixed itself.. battery and brake late are now off after my 3rd or 4th startup of new engine. Possibly needed a few cranks to figure itself out. Running 12.4 Volts off and 14.4 engine on so that's good. Unfortunately, radio isn't producing any sound but maps and everything works. This will be my last issue to solve though lol.
