Converting the Jeep to 24 volts was the original plan but it didn't
pan out for a variety of reasons, none the least of which is that
civilian equipment manufacturers haven't quite caught on to the
advantages of 24 volt electrical systems and insist on making 12 volt
power supplies.  Another reason is that the 24 volt equipment is
premium since the trucking industry here tends to horde things like
that for their own equipment.  (I also thought about marine and
aircraft but they're worse yet.)  In the end, it winds up a lot
simpler to make some small 12-24 volt converters and park them by the
battery, although upgrading to a nice fat alternator and dual
paralleled batteries (like my old F-250 Diesel) in the process
wouldn't hurt.  Where would battery #2 go?  Well, I don't carry
passengers a lot anyway.  :-)
