Its a -52. Ill try looking at those first. I did open the right forward access panel and there was an electrical box/panel marked AC panel immediately on the firewall, based on your picture Im not sure thats the box youre referencing. If thats not it, which way from that box? Sorry new to the yak.

YAK-50 does not have this facility but if putting a voltmeter on #6 relay from fuselage ground to each of the 4 connections in turn gives a voltage reading on one of them (#2?) then the fuse is good. FYI - I've had this relay(#6 TKD501DOD) fail on me some five years ago in my -52 and replacements are hard to come by. If no rear warning light / voltage then likely the fuse has failed mechanically or become corroded ... always be wary of big fuse failure as it may be the result of a major short elsewhere. YAK-52 fuse is 50A & -50 is 20A. So proceed with caution in replacing it ... you could remove the fuse and put a ohm-meter from the downstream side to fuselage earth and see if there's a very low reading (i.e. c.

As mentioned, it was "6" 5010 relay/kontactor. The "7" is the relay/kontactor for ground power. I believe they can be swapped in a pinch.

So worth examining these carefully too.
