Problem solved...it was the extension cord (50ft 12 gauge cord with LED end). Cord worked fine on its own with preheater, but would not with any smart plug in the loop. Not sure why. Switched to a basic cord with no LED end and now setup works fine. BTW in the process I upgraded to a great smart relay. It shows power consumption and has bunch of nice features. https://us.shelly.com/products/shelly-1pm-gen3

I have a Reiff system on my M20J (standard system). Has been working fine using a 50ft 12 gauge extension into GFCI. I recently obtained WiFi at the hangar and went for a smart plug for on/off from anywhere. So far I've tried two - Kasa Smart Plug HS103P3 and Tapo P400M. Both are rated for 15A and 1800W. For some reason preheating won't occur through them (after many hrs engine at ambient) despite the extension cord LED indicating power at engine when plugged in as usual. I'm confident both plugs were switched on the full time. I've also retested system plugged directly in with same extension which works fine. Has anyone else experienced this, and what do other people use for their smart plug? Thanks!

100% on the missing washer. Learning as a new M20J owner and didn't know about SB without asking here :-) If anyone could provide OD and length of bushing 914020-001 I'll work out the rest...Thanks!

You are correct. I referenced IPC Figure 2 incorrectly for my serial number. IPC Figure 1 would be correct, but I don't have the setup shown with Cotter pin. From pic you can see it seems to match SB M20-231 setup as shown in Figure M20-231-5. Figure M20-231-5 does give me a better idea. I don't have the extra washer between the baffle and hinge assembly. But I'm not sure there is a bushing inside the hinge assembly at all right now which may be contributing to bolt slowly backing itself out of nut plate. What is the correct OD and length of bushing 914020-001 (so I can source one)?

RHS outboard cowl flap hinge bolt continues to loosen itself on my `78 M20J (shown below). 1) How do I correct this problem? Cowl flap movement is slowly backing bolt out of integrated flap nut. 2) Is the bushing easy to replace by hand if replace bolt and washer(s)? 3) The parts catalog indicates two washers with each hinge bolt assembly (71-10-01 item #12) yet I only see one on aircraft. Where is second washer supposed to be installed? Thanks!

I do not know which series of servos I have, but I will ask. Thank you for the insights!

First time Mooney owner and proud 201 owner!...first post on what else my INOP KFC-200 :-) I have a KFC-200 with KI-256 and Aspen Pro Max. The AP and FD appears to work fine on the ramp - in both pitch and roll the yoke will follow the FD cues. Avionics tech believes torque to be appropriate on yoke. The roll servo motor has been replaced, cleaned, bearings replaced, and likely eliminated as cause. However, in flight the AP will not move the yoke despite the FD showing correct motions both in KI-256 and Aspen. Initially I was focused on roll not following HDG, but it does not seem to follow in pitch either when ALT engaged. Has anyone seen this situation before or have ideas on cause? Thanks!
