If it were mine, I'd attach a meter to the two ends of the resistor with alligator clips so I could read the voltage across it without having to get to it with probes. (You probably already did this.) To cause that resistor to overheat so much that it make a popping sound in a few seconds...

Have you verified that the glow plug is working?

The resistor has to dissipate about 24² ÷ 56 = 10.28 watts. It does this only when the switch is held in the start position. It's rated at 25 watts when properly mounted to a heat sink. It can handle 10 watts intermittently as it needs to in this application without being mounted to a heat...

You're welcome. Nothing is guaranteed though... including my help. :)

You're not getting exciter field current from the usual source. When you hold the switch in the start position, current is supplied to the exciter from the 24v battery. In normal operation it comes from the X windings of CVT1 (X1, X2, X3), goes to the diode board to be made into DC, then...

Interesting story. As much as I've tried, I've never been able to correlate battery brand or battery cost with battery life. A couple Walmart Everstart Maxx group 24 batteries lasted nine years in my 003A, and I've never put a charger on them. I just run the generator once a month if I can...

It would take quite a commitment if you wanted the whole system to be 12v.

If you want simple, inexpensive, and reliable but not glamorous, this type works fine. I've had one on mine for 8 years and it works well.

Also any electrical/electronic equipment that has a power supply that first converts AC to DC (like most do) should be OK on 400 Hz. I'm not guaranteeing this of course. :)

Wow, 300 lbs! They may take a load for quite a while before they get hot! Are they made so they can be configured? Like can you unplug modules to increase the resistance, for example?

You could put several of these in series, adding 1.5 ohms each time you add one. The catch is knowing how much power they can handle for some reasonable time like several minutes or an hour, or whatever amount of time you want to load the generator. I'm not familiar with them to know the...

Actually while that's true for many generators, it's not true for the 002A and 003A. The regulator controls the generator output by passing a small control current through the control winding of CVT1, causing its output to the exciter field to be reduced. This means that if you run below 1,800...

As Guy said, its in the -24 manual. https://www.steelsoldiers.com/threads/all-the-tms-you-need-to-work-on-the-mep-002a.155935/

Now that's funny!

We have too much rainfall here for that to work. :)

One has to think along the lines of "What did a huge current spike damage?" Does your reconnect switch work as it should, allowing you to select single phase and 3-phase configurations? The contacts in that switch had to take some abuse during the "event". Forgive me if this was covered...

If it were mine, I'd assume you're within measurement error of correct. But I'm going my experience with transformers in general, and not the very special CVT1. (leaving an excuse in case I'm wrong)
