Hello, looking for some troubleshooting tips for my Volvo penta on my 55#13
After replacing the starter battery the engine doesn't start. May be my last try to start the engine with the old starter battery was damaging the pcu. I measure at pin B32 only 10.5 Volt. All the relays and fuses are ok.
In the engine room I find a box 12 and 24 Volt with Murphy Relais. I think this is for the two alternators.
Any help is very much appreciated.
