Yes that is correct. The relay is merely a remote controlled switch. Open means the GP's are not getting power applied to them, Closed means the GP's should be getting voltage from the vehicle power system. In your case, that is from the resistor.

Check the voltage on the orange wires at the GP relay with it closed. It should be around 12 volts. Open should be 0. The wire from the resistors should be around 24 volts open relay, and 12 volts closed relay. The green wires will not have any voltage on them when the GP relay is open. When its...

It's an obsession... Schematic for your enjoyment. Of course, add fuses at the correct locations for your protection...

I added an extra voltmeter in so it monitors the GP voltage then auto switches to the 12 volt side of the electrical system when the card opens the GP relay. Much more accurate than a LED.

I have soaked a couple of sets in paint stripper using a disposable aluminum pan. It takes a couple of days to get it to soak in. After the majority of it was removed, I used a dental tool to pick the coating out of the interior corners prior to sandblasting and powder coating.

Added a breaker box and connectors so I can power things a little easier from the gen set. Now to get the tail lights working.

I have 2 M1008 trucks. The first one was named Leonard. By the previous owner. This one might be called Nimoy. Live Long and Prosper....

Thanks for the update.

It came on in Low, Med and High.

Taking the truck out for a ride today. See what else fails.... I still need to come up with a name for this truck..

Kally, No offense or other demeaning connotations intended on my part. My apologies if I sound harsh. This may help you understand the GP system: GP Module Theory of Operation Keep asking questions and we will help get your GP system working. Figuring out other peoples wiring can be difficult.

Looked at the electrical schematic and saw that the GEN 1 light and the heater share a fuse. GEN 1 light did not come on with the key. Checked the heater fuse and found that it had blown. Replaced fuse and the GEN 1 light acted normal. Then it blew again when I turned the fan on. Replaced fuse...

The GP card has a couple of variable inputs that determine the duration of the glow plug heating time. The colder the engine is, the longer it keeps the Wait light on, the warmer the engine is, the shorter the wait duration. The GP card also provides the after glow heating of the glow plugs...

Turned on the heater fan and the GEN 1 light comes on.....

I bought this earlier this week. It's has the normal CUCV gremlins. Plans are to use it for a little while then take it down to the frame and do a full restoration.

Welcome to the site!

In PA, It would be best if he had a title. PA will accept an SF97 from the Govt. or a Bill of Sale if you are applying for HMV tags. I have used the SF97 to get a regular title. I am not sure if they will accept a Bill of Sale for a regular title. PA HVM Facts

HAHA, Tower guys have been doing the zip tie trick for years! Also, don't go to sleep in the truck when someone else has a black Sharpie marker....

Using on an online voltage drop calculator. Voltage Drop Calculator Stock 18ga wire 5ft in length will have a drop of .796212 volts. An upgrade to a 14ga wire 5ft in length will have a drop of .394920 volts. So one can expect a .401292 volt increase by going to a 14ga wire at 12 volts with a...
