Then he can just leave the motor running. It won't use that much fuel at idle

This is a good point. Some vehicles have a cigarette lighter fuse that can
be moved from an ACC to BAT position. In the BAT position, the cig. lighter
outlet is always hot. Fewer things some on in ACC position than ON. But ACC
can still be a battery killer.

Another 'always hot' circuit is the dome light. In some vehicles, the door
switches provide the light a ground.

Which is exactly what I said back on May 7th.

Thanks for all the replies. Rigged a cigarette socket with alligator clips and long wires. Direct to battery. Ran 10 hour test (only need 6 hrs. sleep) and car started fine.

Free safety hint... put an inline fuse at your positive alligator
clip. Always fuse anything connected to the positive battery
post, at the post.

What fuse would you recommend for this application? Thanks.

Depends on the anticipated load. The wire gauge also depends
on the load. For a specific load, the longer the wire the heavier
the gauge needed. There are charts for sizing wires to load and
length. He's got a temp hook up. Does he need a weatherproof
inline fuse? He would know better than me. If permanent hook up,
go weatherproof.

Mostly, I like to know what would be the suggested amp rating of the
fuse with a 36W maximum load.

For DC, Watts = amps X volts

36 = ? X 12
therefore ? = 3 amps. I'd use a 10 amp fuse.
