Thanks very much. I will let you know how it goes.

Thanks very much for the detailed post. If you have the schematic with to pin out that would be very helpful. The Mooney maintenance manual does not give a pin out. Thanks very much for your help.

I know this thread is a couple years old, but my annunciatior panel high/low voltage is flashing even though my Engine Monitor shows 14 volts. I have 78 m20j and have read the service manual sections and your posts here. Adjusting the pot seems straight forward, but do you have any information on the calibration procedure while adjusting the pot? Thanks.

Thanks. I tried them again this morning and was able to reach someone on the tech support extension. All my previous attempts was through the sales extension, which went unanswered. The person I spoke with was very helpful and provided me the part number and the price, which is $596.00. Carl.

Thanks. I tried Century several times. No one answers the phone and you are instructed to leave a message, but I have not received a return call. I will try again. Maybe they are effected by Covid?

The yoke mounted electric trim switch went out on my 78 m20j. I verified that it is the switch, but am having trouble finding a replacement. I've read that you can replace the individual switches, but would rather try to source the trim switch as a unit. I've tried Century, but just get a voicemail and no one returns my call. Any suggestions about where I might find a switch? Thanks, Carl.

I just went to the web site and saw the same thing; https://buy.garmin.com/en-US/US/p/604257#additional

Thanks. Exciting that the STC has apparently already been issued for the J Model. I agree with you that the announcement should be out very soon. My Century IIB just came back from repair. It does a nice job with GPSS but nothing like the capability you have.

The Garmin website has shown M20J STC as being underway for a long time? My inquiry about the status went unanswered and I was wondering if anyone had any new information about potential timing? Thanks,

Thanks very much. I was able to get it in to the mechanic today and they are going to look at it together with a few other squawks. I will keep the info in case I need it in the future. thanks again. Carl.

I have a new to me '78 M20J. During the pre-buy the mechanic pointed out that there was a foam filler piece missing between the duct and the oil cooler on one side. The oil temps are fine, but I would like to replace the filler piece. I looked in the Mooney Parts Manual and it is listed as part no. 620017-000 but when I google that number the only hit is Lasar and they are out. My question is whether there is generic foam tape that is suitable for this application and if so the brand/type. It seems that whatever is used should be suitable for a higher temp environment and that just a generic brand from Home Depot is not appropriate. Thanks. Appreciate any help or advice.

Thanks for the information AJ. Appreciate your help.

Mike, Appreciate your e-mail and thanks again for your thoughts and this additional sage advice. Carl.

Do you have contact information for Sue? She may know the individual that Kentucky Airmotive suggested, if they worked their at the same time or be able to give me thoughts on others in Lexington area who she might recommend. Thanks very much.
