No damage. > Would it warm the engine up in 20 or 30 minutes like it does > on 120 v ac? No. Well, actually "yes", but only a few degrees warmer and very slowly. *smiles* An 800 W heater at 120 V becomes an 80 W heater at 12 V. Sorry. Now if you could find 10 batteries to connect together in series (A- to B+, B- to C+, C- to D+, D- to E+ etc.) it would work just fine! > Would an inverter be required just to run a resistance > element? Yes. > Anyone BTDT? Thanks. Curt used to do that every morning 'cause he couldn't use an extension cord to plug the car into "shore power". You will need an inverter rated for at least 800 watts, which is not one of the inexpensive ones. Or use a generator. -- Philip _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
