I am working on installing a 12V glow plug relay in my Mercedes. The motor has 12V glow plugs so my idea is to replace the 24V Glow Relay with a 12V Glow relay and install 2 resistors in series before the realy. Hence stepping down 24v to 12v. The relays are rated at 80 amps and from my calculation the watts is 1920w. The online ohm calculators indicate (2) 0.3 ohm resistors.
Any idea on what can be done to address the watts? I might be a little confused as I dont see any 0.3 ohm resistors capable of handling the 1920 watts.
