12v amp draw

[corelokt]

How much of an amp draw does the 12v feed draw at max? IE. How much is the most current going through the wire from the front battery to the 12v connector with the glow plugs running on the same circuit?

Also, if a component has a separate ground, ie. a ground wire and no ground through its' case, can it be run off the back battery bu connecting to the bus bars?

The glow plugs will draw around 100 amps when connected to the front battery with the resistor by passed.

Add lights, heater fan, GP's etc ~ 125 amps is my guess.

Any accessories that you may have added will increase the current demands.
