I just bought a 2000 340 Sundancer with an ECM issue on one engine.
If I energize only the STBD main battery solenoid switch in the cabin, the volt meter indicator shows voltage but no power actually powers the switches for the accessories like cabin lights, stereo and other switched on devices.
Now if I energize only the PORT main battery solenoid switch, it powers the lights, stereo and all the other switches but does not show voltage on the meter indicator.
Do both of these main solenoid battery switches have to be on? With both STBD and PORT main battery solenoid switches on, everything seems to work OK but this seems strange to me that you can only operate the accessories on one.
Is this normal operation ??? Please help me understand this
Thanks Gary
