Further to what Neil just said, In a nutshell, if your alternator is not
connected to anything at all while spinning it will be impossible to
regulate its output voltage (as the electricity it is generating has
nowhere to go) so may spike it's internal voltage as high as several
hundred (or more) v
Nick,
It would help if you could describe what the switches are labeled (if
any) or as an alternative describe the wiring of where these switches
are located. I have an older C&C with the "Off-1-2-Both" BlueSeas
Battery switch which I am planning to change to BlueSeas "Off-On
Combine" battery
Nick,
If the voltage sensing line on the alternator is disconnected, that can
lead to the alternator (via the voltage regulator) putting out high
voltage and damage can occur from overheating. Not sure why someone
would put a switch in this wire if that's what it is, as you would never
want t
I had a 1978 C&C 34 on which I installed a Blue Sea system switch to control an
extra engine-dedicated battery (while leaving the old 1-2-all switch in place
for the house bank). I also installed Lewmar opening ports. Is your boat
green by any chance?

Nick,
By “switches” do you mean the Battery Selector Switch? It’s often red and has
different positions like 1, 2, ALL, NONE or OFF. If so, this determines what
battery powers your starter… and in turn, which batteries receive charge when
engine is running. Common advice is to NOT pas through t
