Sorry, intended to say MEGA fuse. My mistake. Karl

I used a piece of #2 from the batteries to a modified DC distribution block and then shortened the factory wire with the fusible link to the 12 volt junction near the GP relay. I moved the buss bar over one hole to allow for a 12 volt only stud, the rest of the bar is still 24 volts. Eventually...

I finally had time to measure the GP current and voltage today on a stock M1009 that has the standard resistor bypass procedure completed. Test Set Up: Cold engine approximately 58 degrees F. 4) AC60G glow plugs connected. Resistor bypass procedure completed. Installed ammeter inline at the...

This is on my list of electrical modifications to do as well.The only difference is that I am planning on adding a 125 to 150 amp circuit breaker or fuse. I will need to do a little more research on what my current demands will be. Any additional wiring that is done in a vehicle needs to have a...

That's a great question. Unfortunately I no longer own that truck. But I do know that the batteries were good. So I would guess/estimate that the voltage was around 12.8 VDC. I did not measure the voltage before, during or after the tests. I was just interested in current draw. I may just...

I finally found the ammeter pictures. Full scale is 50 amps on the meter. One picture is the current draw for 4 glow plugs and the other is for 2 glow plugs. The pictures were taken after about 5-10 seconds of heating time. This M1009 truck has the resistor by-pass modification. Karl

I used an ammeter on one of the orange wires that feeds 4 of the glow plugs a the GP relay. The engine was not started and was "cold". I observed the meter deflect to the far right of the meter between 45 and 50 amps. So 100 amps is a safe number. I posted a picture of the actual current draw...

100 amps. I measured it.
