Your Plane Power didn't require a "Field" switch? 

[Andy95W]

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.

I don't understand the question? I have a field circuit breaker already if that's what you mean.

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.

Mine has a toggle switch/circuit breaker (same switch as the boost fuel pump).

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...

PP thoughts only...

That's the sequence on my ck list for start up, reversed for shut down

[Browncbr1]

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.

Just now, Andy95W said:

He doesn't have the plane power regulator, just the Alternator. I think he has an old interav regulator. 

[Raptor05121]

I have a Prestolite unit

[Andy95W]

My bad.  I thought the PlanePower alternator STC required the use of the PlanePower voltage regulator.

[Raptor05121]

I think I'll be upgrading to a Zeftronics unit if this one goes bad.

All are tied into the Master on mine. I do have separate C/Bs for them, though.

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

[Bart Chilcott]

Alex, were you getting any type of belt squeal from your old alternator?

 

[Raptor05121]

Not at all, Bart.

[romeotango]

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?

[Raptor05121]

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

[romeotango]

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.

[MB65E]

 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.

[romeotango]

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.

[RLCarter]

I had the larger flywheel/pulley and had to go with a longer belt, can get the belt # later this afternoon 

[romeotango]

RL That would be fantastic. Thanks!

[RLCarter]

@romeotango here ya go

[romeotango]

Thanks RL. The help is very much appreciated.
