0TreeLemur Posted February 15, 2018 Report Share Posted February 15, 2018 When recently replacing the panel in our '67 M20C, one of the (original?) circuit breakers broke. It was a 10A. There was a spare 15A so we used that one temporarily. Can someone recommend a contemporary replacement? It was connected to a bus bar on the bottom, and power out on top. It has a similar look to the Klixon 7277, in that the screw terminals are slanted. But- it just doesn't look right. Suggestions appreciated. The top part of the case broke when my son put a screwdriver on it to loosen the screw. Given the brittle nature of the one that broke, I'm guessing others might be brittle too.

tony Posted February 15, 2018 Report Share Posted February 15, 2018 When I upgraded my panel, I replaced all my breakers and saved my old ones in a box. If you post a part number and I have what you need, I'll send it to you. Quote Link to comment Share on other sites More sharing options...
Oscar Avalle Posted February 15, 2018 Report Share Posted February 15, 2018 Same started happening to me a while ago. My old breakers started to brake... I looked into replacing some of them, but then I discovered that the bus bar was in bad shape too, so I decided to redo the whole breaker panel with new breakers.

Marauder Posted February 16, 2018 Report Share Posted February 16, 2018 Based on what I am seeing on that new breaker panel, it looks like you have room for new avionics. What’s next? Sent from my iPad using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...
carusoam Posted February 16, 2018 Report Share Posted February 16, 2018 Fred, If you are looking for a source of the circuit breaker, might I suggest... http://www.aircraftspruce.com/catalog/elpages/pbcircuitbrkr.php?gclid=Cj0KCQiA_JTUBRD4ARIsAL7_VeVCnfj23hrf1rEF1aAXrLOirRUqo6_4fzIb9EqWuNVMWWDJ9kJlqjgaAhXwEALw_wcB Check the part number on the one you have against what AS has. You should be able to get an exact replacement. The old mechanical CBs have a tendency to wear out and not carry the full load after a few decades... typical failure of the landing light CB.

Additionally, even if I wanted something new, I really don't know what... may be a should look into upgrading into a 201 take all the avionics out and transfer them to my new plane. 1 Quote Link to comment Share on other sites More sharing options...

They are brittle. Quote Link to comment Share on other sites More sharing options...
