T&T: 24V starter, 12V house bank - Ugh!

[Mark Andrew]

Just had the air starter on the Cat 3306 replaced with an electric starter.
Wasn't paying the attention I should have, was away from the boat, and the
Cat Dealer installed a 24V starter, and I imagine it's a done deal.  My
house bank is a large group of Trojan batteries wired for 12 V, my
Inverter/charger charges & uses 12 V.  My gen set starter is 12V.  The
alternator will be a Leece-Neville 12V. Ugh!!

 

Any ideas?

 

Do I get a 12-24V transformer for charging while underway & a  24V charger
for dockside?  Do I shoot my other foot?  Scuttle the boat? What do you
think?

 

Embarrased,
