I hope it works out. I just got the dc-dc converter in today. I should be able to get it installed this weekend. Its just a very tiny chip based converter, it can only handle 1W of load. But, it should work great for this signal level stuff. I tested the sense wire on my alternator and it pulled 1mA.
I am also hoping to add a few transistors in as switches so I can enable the alternator on demand for some regen braking capability.
However, first steps first. Today I just unplugged the connector on the alternator. Yep, that worked haha.
