This is probably in that large category of dumb questions, but I'm replacing the 40 amp Univolt on my '70 Overlander with a Newpark 40 amp. Aside from having fewer fuses and circuits, if that's the right word, the new box also has connections for only one battery, the one from the trailer. The original Univolt has two, one for the trailer battery and one for the auto battery. My question: What is the purpose of having a connection from the car battery? I guess if the auto battery is run down, you could charge it, but since electricity runs both ways wouldn't it pull power from the trailer battery when you crank the engine? So, in connecting to the new voltage converter should I try to jury rig a connection to both batteries, or just to the trailer battery? --Lan Sluder To unsubscribe or to change to a daily Digest, please go to http://www.airstream.net/vaclist/listoffice.html If replying back to this message, please delete all the unnecessary original text from your reply.
