Bill,
During your annual, we'll take your alternator to a place I use and
have them check it. If needed, we'll have them replace diodes. I
agree, PP needs to make, not only a lighter mousetrap, but a better
mousetrap. Otherwise what's the point? I have a new PP alternator on
my shelf for my plane. If it isn't a better alternative to a Kelly
rebuild, then I'm going to stop recommending them.

I've had a PP alternator on my AA5B for about 3yrs now. It has never
given me any problems at all. No noise or any other problems.

I've had a 24volt PP alternator on my Tiger for 4 years without any
whining until last flight when Grumman Gary was sitting in the copilot
seat. No the whining was not Gary but the alternator. The street lamps
would light up when Gary drove under them too. I think that Gary has
too much energy and his brain waves are interferring with the magnetic
fields. This theory may also explain why Gary's JPI grounded probes
read higher than the EI nongrounded probes.

Some guys just have it....
