But I would consider wiring the old Generator switch in to disconnect the Pmagnet alternator from the rest of the aircraft.

This is the one on my Yak 55. The photos at the bottom show the unit as mounted on the upper back of the case. There are just 2 wires that leave the Alt going to the regulator, blue in the photo, just behind the right mag The regulator is mounted in front of the firewall on the right, below the oil tank and medial to the battery tray. There are 2 wires leaving the regulator red/blk that enter the wiring harness. I have not unwrapped the whole set of wires as the problem I had related to the 2A CB just before the bus. In my installation the Alt is not switched on the panel. The old "gen" switch is wired into to the main breaker panel and the CB for "gen" is pulled so the GenFailure light on the panel is not lit. The voltage meter in the cockpit is wired in as i can see if the Alt is not charging. I can also see a variable output with the engine speed. i do not pretend to know all of the facts, but reading the long discussions i am not sure mine is wired right since the switch is inop.

One would be to put a diode in line with the main feed AFTER the wire that leads to the old generator light. This would allow the light to come on if the alternator or any part of the regulator circuit, or the over-voltage protection failed. Of course the kit already contains a NEW light that you put in that tells you when the over-voltage relay has tripped, but I think I would like the idea of the old generator light telling me that the new alternator system had failed (in any way) better than that. It is all up to the installer, but if you can think of what you want, and how you want it to operate, it can likely be re-designed to do that.

Works well but II've connected the output of the regulator circuit (behind the crowbar) to the main bus in my Yak50 (in the big black box mounted on the firewall at the inside; "shitok pitanije" or something but in cyrillic). So the "generator fault" indicator now serves as a "master on" switch. I've another light for the alternator fault.
