I dunno but the wires would probably have to be fairly heavy to pull 8a. My
400w inverter isn't to be run using the car's cigarette lighter...
800w inverters aren't all that hard to find are they? You could also drain the
oil, warm it up inside and put it back in. I'd briefly considered the idea back
when I lived in the apartment and was trying to keep a 240D running (or rather
being able to shut it off at night and restart in the morning) through a -20F
winter.

Subject: [MBZ] OT 12v dc to 120v ac heating element?

One of you technical guys must know this.
Say you get your diesel tractor suck in the woods a long way
from the 120 volt ac outlet that would normally power its 800 watt
engine preheater. Night is coming. It will be very cold in the
morning when you return with chains, come-a-longs, etc. to extract
the tractor. Let's say you happen to have a charged 12v car battery
that could carried to the scene. If the + and - poles of the battery
were wired into the slots of the 120 v ac plug would the heater work
without damaging anything? Would it warm the engine up in 20 or 30
minutes like it does on 120 v ac?
I tried researching this on the web but all I get is a lot of
talk about the right size inverter needed. Would an inverter be
required just to run a resistance element? Anyone BTDT? Thanks.
