Altitude Preselect KAS297B

[Jungle Pilot]

My KAS297B altitude preselect died.  It is p/n 065-0065-00. I am replacing it with a slightly newer p/n 065-0065-01.  I’ve read that a “-00” can be replaced with a “-01” with harness/connector pin change. Does anyone know how to make, or what is that pin change?

thanks,

Dave, I found a SB that says that the -01 is an approved replacement for a -00.  As far as I can see the -01 was to make it compatible with a KEA346 altimeter.  BendixKing was in the habit of installing 'blank pins' in connectors to make sure you could not plug the wrong device in.  

Send me an email.

Thanks Aerodon,  FYI I have plugged in the KAS297B … -01 into the existing connector. It powers up but only shows dashes across the screen. I need to find out what that pin change is.

Thanks to another lead, the answer to installing the KAS296B p/n 065-0065-01 into an existing KAS296B p/n 065-0065-00 panel is Bendix/King SB286 which states that pin # 28 must be grounded if you have KEA 130A encoding altimeter, which I do.  I will ground the pin and report back.  Currently I only get dashes across the screen.
