This is a show stopper for me. It takes a minimum of 13 amps to drive the fuel injection and ignition system. I agree that 1 hour endurance is a reasonable assumption; I am using 45 minutes to allow for greater than expected battery degredation (I wiill replace the battery yearly). I agree that the EWP will shorten this endurance considerably. Dual alternators would minimize this risk. Unfortunately 2 alternators just will not fit under the cowl of my RV-4. I am considering a snowmobile/motorcycle type PM alternator but I am a LONG ways from addressing this feature. So I will add to Bulent's question - what will be the current draw at 25 gallons per minute when installed in a functioning cooling system?
