RLCarter Posted September 25, 2017 Report Share Posted September 25, 2017 Your Plane Power didn't require a "Field" switch? Quote Link to comment Share on other sites More sharing options...
Andy95W Posted September 25, 2017 Report Share Posted September 25, 2017 Congrats on getting your plane fixed. FYI, the RG batteries can be finicky on charging voltage per my attached photo from the Concorde battery Owners Manual. It is an easy adjustment on the voltage regulator. There is a potentiometer near the center of the regulator after you take off the cover. Turn right to lower the voltage. A tiny turn (maybe 1/8 of a turn) is probably all you'd need.

Thanks, I could not find the adjustment anywhere. I'll see if my A&P can pull the cover and get it lowered. It sits at 14.6 but I've seen it as high as 15.0 with everything on.

carusoam Posted September 25, 2017 Report Share Posted September 25, 2017 Modern Mooney panels have... Master switch/CB Alternator switch/CB Instrument panel switch/CB The alternator switch is probably switching on/off the field wire... this allows the pilot to activate/deactivate the alternator...

Browncbr1 Posted September 25, 2017 Report Share Posted September 25, 2017 The voltage adjustment is on the regulator. someone has to adjust it with the cowl off while someone is in the plane running it. As I recall, mine was set to 13.8v and I can't remember if that is at idle or higher rpm... I used a breaker that can be pulled to turn it off rather than a proper switch.

Andy95W Posted September 25, 2017 Report Share Posted September 25, 2017 My bad. I thought the PlanePower alternator STC required the use of the PlanePower voltage regulator. Quote Link to comment Share on other sites More sharing options...

Raptor05121 Posted September 28, 2017 Author Report Share Posted September 28, 2017 She's flying great. Today was the first day where it actually felt like fall. No clouds after 5pm, sky smooth as silk. I shot down to my CFIs house for a chat about getting back into the IFR training regime, then popped on over to my mechanic's place (beautiful 2300' grass strip) for some hangar flying. It wasn't long before my girlfriend was ready to get back and eat 7 Quote Link to comment Share on other sites More sharing options...
Bart Chilcott Posted October 4, 2017 Report Share Posted October 4, 2017 Alex, were you getting any type of belt squeal from your old alternator? Quote Link to comment Share on other sites More sharing options...

romeotango Posted October 7, 2017 Report Share Posted October 7, 2017 OK, I have finally gotten fed up with my old InterAv alternator eating brushes and am going with a Plane Power. The belt I used with the InterAv was a 37B19774-374 but it seems too short for the Plane Power Alternator. What are you guys using? Quote Link to comment Share on other sites More sharing options...
Raptor05121 Posted October 9, 2017 Author Report Share Posted October 9, 2017 I used the same belt thats on my plane. I can check for a PN when I go back out there, but it does seem like the PP unit sits a lot closer to the engine. I had to add baffling material to cover the older larger hole around the alternator Quote Link to comment Share on other sites More sharing options...
romeotango Posted October 9, 2017 Report Share Posted October 9, 2017 Thanks Raptor. The belt on my plane is apparently is the one used for generators. I broke a couple of belts when I first bought the plane with the InterAv installed. After several tries, my IA put on the belt that is on it, that was over 25 years ago. I suspect that I need the Lycoming Alternator belt. I can not get a response from Plane Power, perhaps they took today's holiday. Quote Link to comment Share on other sites More sharing options...
MB65E Posted October 9, 2017 Report Share Posted October 9, 2017 Gates green labled belts are ok to use per the STC. The belt that came in the kit didn't fit my flywheel for some reason. I played around with belt size until I found one that fit. 38 3/8" rings a bell. O'Reillys had the best selection of that brand of belts. -Matt 1 Quote Link to comment Share on other sites More sharing options...
romeotango Posted October 9, 2017 Report Share Posted October 9, 2017 Thanks Matt. I received a callback from Plane Power and they recommended a Gates 9335XL. That belt number is only 33.5 inches versus the 37.5 Inch belt I have now. The size you mentioned seems to a better fit. Quote Link to comment Share on other sites More sharing options...
RLCarter Posted October 9, 2017 Report Share Posted October 9, 2017 I had the larger flywheel/pulley and had to go with a longer belt, can get the belt # later this afternoon Quote Link to comment Share on other sites More sharing options...
