Re: [MBZ] OT 12v dc to 120v ac heating element?
For 2/3 the money a 1200w peak 2stroke gas generator is way more useful. I got one a couple years ago for $130, they've gone up a bit now. Mine is supposed to run 8 hours at 50% load on 1 gallon of gas. Its also got 12v out which is handy for charging the starting battery. -Curt Date: Mon, 26 Mar 2012 22:00:37 -0400 From: Dave Walton walton.d...@gmail.com To: Mercedes Discussion List mercedes@okiebenz.com Subject: Re: [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.

Re: [MBZ] OT 12v dc to 120v ac heating element?
might get enough warmth to get the thing to turn over, but no way you will be able to heat it. Lose electrons at the point of inverter, then the pre heater would suck the battery dry in minutes trying to make 800watt clay Best to hit the local harbor freight and get a small genset. I figure 1kw peak, a gallon of fuel would be the same as toting a large enough battery. On Mar 26, 2012, at 5:38 PM, David Kristin Gilmore wrote: One of you technical guys must know this.

Re: [MBZ] OT 12v dc to 120v ac heating element?
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. -Curt Date: Mon, 26 Mar 2012 20:38:24 -0400 From: David Kristin Gilmore dandkgilm...@frontier.com To: mercedes Discussion List mercedes@okiebenz.com Subject: [MBZ] OT 12v dc to 120v ac heating element?

Re: [MBZ] OT 12v dc to 120v ac heating element?
Reminds us how good the preheat system in a diesel MB is. My cheapo (~$30 IIRC) 400w Coleman inverter did the job nicely which leads me to believe the heater in an MB is either over-rated or the inverter is under-rated. -Curt Date: Mon, 26 Mar 2012 20:19:17 -0500 From: Fmiser fmi...@gmail.com To: Mercedes Discussion List mercedes@okiebenz.com Subject: Re: [MBZ] OT 12v dc to 120v ac heating element?
