Location of diodes in the Alternator Restart system?

[Rick Erwin]

Today there was a measure of success.

We ran the engines and performed a pseudo test of the Alternator Restart system. It worked!

The entire system has not been reinstalled yet from the testing, so I just used dry cell batteries to excite the rear alternator and it fired off with 1.5v. Once the rear alternator restarted, the front came up as well. The next step is to reinstall the system and do another test. Since testing has shown I will have 1.75-ish volts at each alternator's field terminal when the system is installed, I'm hoping I'll be good to go.

I did see it would NOT restart with ANY load on the system though. Since an alternator's field has about a 3.5 amp load, I think it would be advisable to only try to restart one alternator, then turn on the other alternator.

There will be more testing to follow.
