lightweight alternator?

FRIEND
Port Townsend, WA
A friend of mine is building up a modified Pacer & is looking for a good lightweight alternator set-up. Any suggestions? I have an Interav 50-amp on my C150/150, and while it is a clean install & works OK, it doesn't seem esp light. Ditto for the Plane Power kit. B&C makes a nice one but it's experimental, maybe/maybe field approvable. I saw a little Nipndenso alternator (35 or 40 amp?) mounted on a Swift a while back- nice & small & light. The mechanic working on it said it was field approved. Does anyone make an STC'd kit with one of these little dudes?

Lowell Miller at Crookston Aviation (218-281-2625) has been getting field approvals for an 8.6 lb, 60 amp alternator with a built-in voltage regulator.

Last time we traded emails he said it was $300. It's a slick little unit, and would free up a bunch of space inside the cowling.

B&C's are STCd and work perfect... They are a great bunch to work with and make a great product.. I once bought a "used" B&C starter off ebay,,,It looked ok in the pics so when it showed up I hooked it to a booster pac at the kitchen table and it was shorted out. I took it apart and it looked like it had been submerged in salt water then set on the shelf for a few years. I called Bill @ B&C and he said "send it in, we will fix it" so I did. It came back looking NEW for just a touch over 100 bucks and is not starting a IO540 in a Maule.

Thats great service in my book!

The 8.6# 60A alternator mentioned is still sorta heavy, and more amps than a lot of us need. B&C's 40A is more better at 6.1# but still with more than enough amps, but unfortunately they're kinda spendy- almost double what their experimental 40A models are. And per their website, they're STC'd for PA-18 & 19's, so it'd still be a field approval for a PA-22/20.

Well, my buddy bought the B&C 40 amp alt that approved for supercubs, and will go for a field approval for his Pacer. It is a nice small light unti, for sure!
 
Hey, I've been getting field approvals for the Denso 40 amp alternators on Cubs and Cessna 180's.

No problem. Light, Inexpensive, and internally-regulated so you lose the problems of an external regulator, noise filters, etc., such as the Inter-av's. They are available in Anchorage for $125. It's a fork lift or Argo ATV alternator. I have been told that the B&C's and also the PlanePower's are this same unit with the internal regulator removed. Anyone know if this is true?

I always mount a large output circuit breaker and a smaller field circuit breaker. The fed's have loved it so far.

Is the rest of the USA having problems with field approvals still? My impression is that the 'new' field approval directives were to standardize the process?! Is that so?
 
Dave,
I'm ready for an Alternator on my experimental. Where in Anchorage (I'm in Girdwood)? What part number.
Thanks, laz

How are you driving this alternator? Belt Drive or Direct? I would be interested in knowing more about this installation, I'd like to get rid of my generator. Please send me a PM with your contact info I'd like to discuss the field approval process for this on my 56 PA-18A with a 150hp

Thanks

Dale
 
So sorry for the long wait for a response with the alternator part number.

It's a Denso 18504-6220

Again, apologies for the tardy response. DAVE

Dave, What are you then doing for the mounting hardware? Thanks in advance, Greg

Greg, I've been "shopping around" the local engine shops and finding the mounts I need.

I had one around here the other day that is 'THE' one. I'll try to find the part number...............don't hold your breath. :D
 
In case anyone is still interested in the 40 Amp Denso. Stoddards in Anchorage, Alaska has been selling the Densos for the last 7 years. They sell a kit for $350.00 which includes the alternator plus the mounting kit. Two kits are available one for the narrow deck and one for the wide deck. Field approval is needed.

Plane Power vs B&C

I am currently doing an alternator conversion on a 1960 PA-18-150 with front oil cooler. This requires a field approval with either company’s kit as both STC’d kits are for rear mounted oil coolers only. I talked to both B&C and Plane Power. They both have excellent products. The differences seem to be that the B&C has a linear voltage regulator and the Plane Power is a pulsed switching regulator. Both regulators are solid state, which means no moving mechanical parts. The linear (B&C) unit may be a little quieter? The PP unit develops no heat during operation. PP claims to have no noise complaints for their regulators. Both companies have balanced rotors in their units. The PP claims to have the coolest running unit.

Both companies have non STC’d/non PMA’d alternators for use on experimental airplanes for around $500, same basic unit no paperwork. I chose the STC’d Plane Power kit over the B&C due to the lower price, $728 vs. $1170. I talked to Bill Bainbridge at B&C at length about his product. He was very nice and extremely helpful. He has also led the fight against the FAA’s very poor 337 Field Approval issue. I would have liked to use his kit but the big price difference forced me to go with the Plane Power unit. Also PP had an example 337 Field Approval for me to utilize which B&C couldn’t supply. Hopefully this will help anyone that is researching this subject. I have a more detailed 337 available for the field approval of the Plane Power unit if anyone would like a copy.

Keep ‘em flyin!

UPDATE: I received the APPROVED 337 for this field approval yesterday. I had it back from the Denver FSDO in less than a week. I either got lucky or did something right. Today will start the install. Let there be electrons!

This is great. I now have a major supply of excess electrons available. Think of all the electronic widgets I have the power to run now. I do love overkill!!!
 
A few years ago Niagra airparts was selling a densco alternator as a kit. Someone wrote up an article in SWP and I installed the same unit on my Colt about 5 to 6 years ago. it has been trouble free since. The alternator is Densco 100211-1680. 35 to 40 amps and very light. Field approval at the time was easy.

The 100211-1680 denso alternater came out in about 1994 was installed on a iszuzu lt truck it was deisined as an industrial alternator it was advertized as the "earring alternator"i installed the first on in Dec of 1997 form 337 field approval on a PA-18

I have been very happy with mine. Do you think it will be any problem to find when it comes time to replace?

I wanted to use a B&C Alternator but leave the oil cooler in the nose, not move it to the rear baffel. Talking to Steve from Atlee Dodge he mentioned they have mounts that will work with B&C Starter and Alternator that allows you to keep the oil cooler in the nose. Received the parts the other day, they look great AND they come with an STC! Will report on the installation, but everything sure looks like it will work the way I want it to, along with all the proper paperwork.
