Hey guys, I have a 1986 CU CV and I converted the glow plugs from 24 to 12 volt. I removed the resistor and pulled power from the 12 volt bus next to the glow plug solenoid. I have a 30 amp fuse in the line and every time I put power to the solenoid the fuse like a dead short. I unhooked the orange wires from the bottom of the solenoid and it does not blow a fuse. As soon as I hook it up it blows the fuse. I looked through the wires and I cannot see any bare spots hitting anywhere. Any ideas would be greatly appreciated. I do have a hillbilly wizard glow plug card installed and it has worked fine for the past 2 years

What fuse value? Glow plugs together draw over 100 amps cold.

The 12V power stud there next to the glow plug solenoid does not have a large enough cable to feed 100 amps.

I'm not sure how many amp the GP draw but my guess is more than 30. Try unplugging all GP and see what happens, if the fuse still blows then you know you have a dead short. I'm no electrical expert but I believe you would need some kind of slow-blow fuse (if even made for 12v) or a fusible link.

The glow plugs do draw right at 100 amps.
You would be better off with a 125amp circuit breaker and 4 gauge wire coming directly off of the front battery.
What is the current draw of the glow plugs?
Who is "we". You make them sound glacially slow to warm-up. Slight exaggeration...sorry, they are not 1 minute plugs.
