Did you find anything out?

Apparently I didn't look close enough. You might be right....but I'll wager it doesn't throw a code if the second alternator is online (I like to live dangerously) P0620 Generator Control Circuit Malfunction P0622 Generator Field F Control Circuit Malfunction P0625 Generator Field Terminal...

Should be a simple test of just unplugging the main alt, with the blessing of your expert. Did you ever toggle the main alternator off with the "Single Alt Select" switch on the left side of your panel? That should be a sign that the computer would only throw a code on low voltage. I scanned...

Also, what about installing a ~ 1 Farad capacitor between the battery and the TIPM? I know it's just a band aid for this issue, but power spikes/oscillation might actually be inherent to the design of this dual alternator setups with abrupt load changes. It would be nice to keep smooth voltage...

Can you just install another evaluation board on the original alternator circuit, that way both alternators are playing on the same field(see what I did there?) Can you hazard a guess as to what frequency it is oscillating voltage? Just curious.

Excellent work! What are you thinking about the installation location of a huge inverter? I have a crew cab, and have been running out of ideas to mount it in an area that might be cool in the summer (inside the cab). Don't believe they will fit under the rear seats. I thought about buying a...

While testing can you check the field amperage for the 220 amp alternator at full field (or just resistance in the field winding)? Kind of curious. My engine is coming back together and I will begin a similar project next week.

I just had a look at my tech manual for my 2006 2500 Cummins, and it appears that the field is controlled by the high side, and the low side goes "direct to ground". Unless the manual is woefully inadequate and over simplifying things, the he should be able to just hook the high side wire to...
