Fun. Using N scale a 4x8 layout makes for lot of stuff.

Nice!

If you have no voltage (12V nominal) on the pink/blk wire with the key on you need to find out why. http://www.steelsoldiers.com/attachments/cucv/274249d1315765997-glowplug-relay-chatter-wits-end-cucv-glow-plug-wiring-diagram-2.jpg

What happens when you ground both inverters to the negative bus on the firewall (or to the front battery negative post) using the same size wires as used on the positive side?

As I understand the circuit you should have full battery voltage at the pink/bk wire (front battery only) on the relay. The card does not 'give' the relay voltage. All it does is ground the other side of the relay. You should read 12.45V or whatever your front battery is at on the pink/blk...

#8 wire will take approximately 472 amps before the copper melts. The insulation on the other hand can not take that much amperage before heat in the copper wire begins to degrade/melt/burn the insulation. How much amperage is a function of the insulation type and the ability of the wire...

I chose 1 ohm for math simplicity (which I need by the way). Series and parallel resistances are calculated differently . Series resistances can just add.R total = R1 + R2 + R3 … Parallel resistance uses the formula:R parallel = 1 / (1/R1+1/R2+1/R3 … ) Identical resistors in parallel...

Warning Thread Drift Ahead Ohms law: E=IR So if we assume that the glow plugs parallel circuit is a 1 ohm series equivalent and then the firewall resistor is a 1 ohm resistance the we have 2 ohms total circuit resistance. E/R = I 24/2 = 12 amps If we eliminate the resistor and refeed the...

Once you get the truck started disconnect the power wire (pink/black) from the GPR coil to see if that stops the noise. I could be one of the other relays under the dash doing that as well.

Put the military connector on the trailer with a standard 4-wire lead off the back (supply side). Then you have 4-wire flat for civilian trucks and the standard military connector for military trucks. That is why I did mine that way, so I can use the standard trailer plug on my military trucks...

I just added a military plug to my civilian truck.

Who shipped the sealed seal OD or Saturn?

According to code you can only use the 90C rating if your lugs are 90C rated otherwise you have to use the 75C rating.

I do not have an answer for this either. If a bulletin was put out it must have been put out for a reason so I would say we all need to do it (or verify it has been done) if we are going to run our generators at 120V single phase only.

In stock form the generator has a wire from the ground stud on the frame into the back of the reconnection box where it is internally connected to L0. If you have this wire in place then you have two neutral/ground bonds in your system. This is a direct quote from speddmon: That came from...

Sounds like someone put 12V lamps in it and did not want them destroyed by a 24V hookup. Double check though. This came from someone on this site. I apologize for not being able to give credit by username.

As I understand what you have written all of your metal parts are tied together and connected to ground (should be) and then there is only one place where the neutral is connected to this grounding system and that is at the main panel. That is how it should be. The question is do you have wire...
