Is it just catching on the edge? Take a little of the metal off the edge of the leg with an angle grinder until it clears.

Sounds like a swellman 070. Listen to Doghead, get the AC60Gs and be happy.

Is the GP relay pulling in normally or is it cycling on and off with very short glow times?

It is my understanding that when the CUCVs were procured 24V glowplugs for the 6.2 were not available. With the advent of the HUMVEE 24V glow plugs for the 6.2 became available. So removing the resistor on the firewall and running straight 24V to new 24V glow plugs seems like a natural upgrade...

People want to help you unfortunately they are not clairvoyant and consequently they need you share with them what you did in your 12V conversion. It seems that you are unwilling or unable to explain/photograph what you did so no one can really help despite their sincere desire to do so.

I just converted to a 12V glow plug feed and installed AC60G glow plugs (after removing my used twice and burnt out swellmans). The truck started last Saturday with it being 18 degrees out and again today with it being 15 degrees out. Doghead offers sound advice.

Congratulations and ......... nopics

I believe that manual or a similar one is available in the resources download section.

If you have large high-resolution pictures or scans you can send them to me and I will put them in a pdf file.

As long as the second meter is fully isolated. (negative terminal is not bonded to the metal mounting parts of the meter) Using the chassis (front battery negative post) as the negative meter connection for both meters then a 12V meter from the drivers side alternator output / front battery...

More than likely someone was 'offended' by his neighbor's evil, right wing, military death machine so he pushed for an ordinance change.

You towed without safety chains?

Do you have 24V at the relay under the dash? When soldier b turns the key to start position do you have 24V at the solenoid on the starter? Did you check/clean/replace the 24V fuse in the fuse block? (along with the rest of the fuses for that matter)

Nice trailer.

Two way radio?

Putting in a new relay with a 12V coil should allow the glow plug controller card to actuate the relay sending voltage from the top/feed side to the bottom/load side of the power terminals. You should be able to measure 10V to 15V from the bottom/load side power terminal to ground when you...

Post some pictures but it sounds just like what ranchhopper has been describing. Basically the glow plug circuit has been changed to 12V. The 24V feed through the resistor on the firewall has been eliminated in favor of a straight 12V feed by moving the wire that connected the glow plug relay...

Yes the glow plug relay does get 24V but only to the power contacts not the coil contacts. In a correctly operating system that 24V is just for a moment until the current flow causes the voltage division between the resistor and the glow plugs. If the resistor goes open no power to the glow...

The back battery negative post is the same electrical point as the front battery positive post. The other half of that 12V circuit is the negative post of the front battery which is bonded (connected) to the vehicle chassis. When we ground the light blue wire with a manual switch to make the...

Doesn't a 12V feed go to the glow plug controller and from there that 12V goes through the pink/black 39B wire to one side of the glow plug relay coil? Then the 12V runs through the relay coil and back to the glow plug controller on the light blue 505 wire? When the glow plug controller...
