All, I have been trying to hook up my bre-heater at the batteries. It has 2 red wires that are cut, and 2 black wires that food to a battery connector. I have been looking through the manuals, but can't find any info on the pre-heater. I assume the black go to ground, but I understand the pre-heater is 12 volts and so I assume the red ones go to 12 volts of the 24 volt battery. Is that correct?
By the way, I am not talking about engine heater. I am talking about the glow-plugs.
