Ernest ,
Are you saying that when your SSR was activated it would not allow battery voltage to your
PM alternator regulator ??
Yes. And a short investigation uncovered information that the regulators are designed so that they have to sense a voltage before they'll turn on. Not an issue when controlling a motor, as Jarrett is considering, but a complete deal breaker when that supply line is also the monitoring line.
If used to control an alternator, the sense line would need some scheme to bypass the SSR. The electrons only flow in one direction through the SSR, so the sense line will have to be on the battery side.
I'm not an EE. Lots of other people know more about this than I. YMMV. Void where prohibited. ETC.
I replaced the SSR with a 60A fusible link. If the 38A generator blows that, it ain't coming back into service on that flight anyway. I thought about replacing it with a contactor, but I already have a limited power budget. A mechanical switch was a possibility, but the cabling and linkage start to become a headache. At some point you have to admit that it is a VFR machine, and the extra complexity is going to cause more problems than it solves.
