From: "Roger Kemp M.D." On the end of the carbon pile voltage regulator is a rheostat with a flathea d screw in the center. Mark Bitterlich will have to chime in on the directio n to rotate it if that is the same system that you have in the 55. In the 50 the regulator is on the upper left side of the firewall above the main air b ottle when standing up in the hell hole facing forward. doc Sent from my iPad On Jun 3, 2012, at 9:38 AM, Mark Sorenson wrot e: >> Gentlemen, >> >> I have read in past posts about the over voltage scenario and feel I am d ealing with the same problem. >> >> I have two Yak 55's one with the original system and one with a B &C.

I would recommend an inspection as it would only mean the removal of the oil pump and then using a mirror visually inspect the 2 tab washers and the retaining nuts. And then the re-fitting of the oil pump /fuel pump assembly. -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of Walter Lannon Sent: 04 June 2012 05:53 AM Subject: Re: Yak-List: Conclusion to the Engine out question --> Yak-List message with posted by: "Walter Lannon" Would it be possible for Bradly and yourself to advise of engine TSO or TSN at this gear train failure.
