The easy way to tell if he eliminated the resistor
Yep, this is what the previous owner of my m1009 did or had done.
My starter is still 24 volt but my glow plugs are being run off the front battery.
The original system used the resistor to drop 24 volts to 12 for the glow plug system so that both batteries were utlitzed.
My resistor bank is gone and the glow plug relay power supply is wired to the middle of my battery bank or basically just the front battery.
Well, it is what it is.
I probably would have kept the resistor and ran the glows off both batteries.
Oddly, if you watch that video, the guy said his resistor caught fire o the highway.
How is that possible if the glow plug system isn't being used?
Sounds like something else happened to cause a short.
Looking at the schematic, there should only be a load across the resistor when the glow plug solenoid is energized.
There is really no way the resistor can overload and burn unless there is a short while the gp system is in operation or something else shorts the power wire between the resistor and glow plug solenoid.
