Something about the diodes that was putting out uneven power that was wreaking havoc on the various electrical systems on start up. Caused some sensors to read incorrectly among other things. All's well since and it's been about a year now.

I would have to say I've yet to see a mechanic with an oscilloscope lol.

The alternator does not provide power during start up.
