I just purchased an '01 Maxum 3500. When I start the port engine with

idea what would cause this? Both engine batteries are new, the third

TIA.

It's eather an electrical problem, or a fuel problem. If the port
engine and the generator share the same fuel feed that could be the
problem, if they don't, toss that idea. Now your generator should have
it's own alternator, which supplies it with it's own 12 volt power. If
that alternator isn't working, and the port engine and the generator
12 volt supply are tied together, the voltage drops when the port
engine cranks that should shut down the generator. A quick test is to
start the generator, and disconnect the generator from the battery. If
it stalls, the alternator isn't putting out any power. The battery
switch for the generator might not be set up so as to protect the
alternator if someone switches it to the off position while it's
running. If the alternator is bad just pull it off and bring it to a
rebuild shop, they can fix it better than new for a whole lot less
money. Let me know what you find.
