Fanatic product. Used on my PA28-140. Say goodbye to alternator issues. Plane power is a wonderful product.

AL12-C60 Hartzell Plane Power Alternator

Did some research before accepting my A&P recommendation for a rebuilt OEM alternator for my Piper Arrow III. The reviews said a new Plane Power alternator was the better option. My A&P had no objection. But the lower price for a new Plane Power alternator closed the deal. New? Lighter? Better low speed amps? AND less expensive? Don’t see that in general aviation much.

AL12-C60 Hartzell Plane Power Alternator

The instruction were missing. Also it cost me $40 dollars to ship my old alternator back of core charge. I purchase a new alternator why do I have to send back a good core.

AL12-C60 Hartzell Plane Power Alternator

Great alternator. Only issue, the bolts that were included were wrong for my aircraft’s installation. Fortunately, my AI/AP had a set that were correct.

The product was not an exact fit but after taking the time to figure it out it has been a beast. Would recommend it to anyone that has an extra 20 minutes.

Easy install and worked great on an O-320 H2AD except the old belt, the correct part number for that plane, was just barely long enough as the pulley on the Plane Power alternator is a bit bigger. Manufacturer was puzzled by this. The only solution appears to be a slightly longer belt but dont know if one is available that is PMAd.

These Plane Power Alternators are great! Small and Work at a very low rpm Installed on a 79 C-182Q All spacers, hardware included for a easy install.

Kit came a day early. Installed easily on my 172. Instructions were easy enough.

Good alternator, longer life that the OEM. Ordered 2 alternators one came in with the wrong pulley. Sounds like it is going to take several weeks to get the warranty processed.

Came with all hardware needed except a washer. Corrected my charging issue. I had to dig out the installation drawing/instructions from Hartzells web site.

As always Aircraft Spruce got it to us on time. Thank You!

Flawless installation foe a Cessna 177. This kit does not have a voltage regulator.

Small, light and powerful, this alternator took about an hour to install (the old alternator had been removed) and aligned perfectly with existing parts. It uses the existing regulator and came on line instantly, kicking the meter up to 30+ amps. It will likely outlast me.

Replaced Prestolite alternator on a Beech C24 Sierra. Direct fit, simple install, took less than 2 hours. The kit contained all the hardware needed and we now get charging at lower RPMs. Only have a few hours on the unit so far, but install was easy.

Installed on my D model Piper 180. Swapped the bracket out with the one that comes with the kit, AL12-C60, and it went on very easily. I wish I had bought a new adjustable bracket arm they sell for $40. Volts right up there at 14.1 / 14.2. The alternator I had was at 13.8. Kept the old regulator and OV relay for now.

Installed on 1978 Mooney M20J. All parts required were in the box and easy to install. Blessed to have A&P and the original designers/owners of PLANE POWER as neighbors to help. Had not seen 14 volts on the meter before this. Does what they said it would do.

Quality product

All brackets and spacers lined up perfectly. The v-belt ran true in the pulleys. Alternator came on line at first start and the radio noise is gone. Five stars so far, now for longevity?

Surprisingly there is no weight listed on the included documentation!

Replaced a Chrysler alternator on a Lycoming IO-360-B1E (Piper Arrow 180) using the Plane Power AL12-C60. Installation went perfect, the design and fit of the P/P is great. I would recommend this Alternator to anyone with a PA-28R-180.

Easy to install low maintenance.

These units are great! Have a ton of them on a fleet I help maintain with 5000+ hours on each without issue. Just bought one for my personal 24V 182Q to replace the aging Hartzell unit before it fails.

Just installed a week ago, so far excellent! I'll return to update in a year.

I recently replaced my Prestolite ALY-8420 in my 1978 Mooney M20J with the Plane Power AL12-P70 and I am very happy with it. The voltage pegs right at 13.7-13.8 volts DC during all phases of engine operation. Seems to work great and was an easy replacement. I even shaved 2 pounds off my weight and balance by switching to this alternator!

The alternator was great! Nice and compact. Lighter than the old one and came in with all the hardware to install it. The only thing missing here was the installation instructions since the hardware that came in is different from the one that you take out of the engine. I had to google it in order to get the installation instructions.

Works great! Minimal instructions on how to install it. Pay attention to belt alignment, reverse the spacers on the long bolt if needed. You may need a new arm for the small mounting bolt.

High quality manufacture. Documentation is sketchy and needs improvement. Weighs only a few ounces less than the 50-year old Prestolite 6406 it replaced. In inferred from the description that the Plane Power would be lighter.

It’s not plug and play on a Cherokee Six. Must do some minor modifications to keep the belt from rubbing against metal. Other than that, it works like a champ.

AL24F60C First One I Purchased Lasted 1600 Hrs. without Issue. The Replacement Lasted 98 Hours,With intermittant Output. Seems Since Hartzell took over the Company Quality Has Gone Down Hill. Only have minimal Hours on the Third,so Will reserve judgement Until it is run in a while. We shall see how Hartzell honours their 2 yr warranty!

A good alternator, but be careful! If you have a narrow deck Lycoming you will need to order a special bracket from Plane Power. Be sure to check the installation instructions on the plane power website ahead of time.

Great alternator! Unfortunately Spruce does a poor job of detailing or describing what exactly comes in the package and their Reference Chart is wrong. There is a generic stock photo showing a PlanePower alternator and some hardware but it is the same picture for every single alternator they sell. Which leaves you wondering if this will fit your application. I first ordered an AL24-F60 (which I now know, is a kit that includes the installation hardware and a 10-5050-1 alternator, but what I got was a 10-5050-1 (bare alternator) Its an alternate part number... Im not necessarily blaming Spruce. There may have been some confusion between our parts guy and Spruce, but what I got (10-5050-1) was a bare alternator with no bolts, brackets or bushings. After a while on the phone with Hartzell (PlanePower) we determined that I did if fact have the right alternator but I needed the attaching hardware. In case youre wondering, I could not use the old hardware because there wasnt any (It was going on a new engine and the old engine was a different model.) So at this point it seems pretty easy, Right? Nope. You cant just buy the attaching hardware separately. You must buy a new alternator with the attaching hardware kit. So I get on the Spruce website and is says that for a 172N I need an AL24-F60. Thats what I said the first time! But then I notice that it says Bracket not included So I scroll down until I find a 24 volt one with the bracket for an O-320 it says I need an AL24-70 so thats what I order. It shows up. Nope wrong one again. It has attaching hardware, but not the correct hardware. So I get on the phone with Hartzell again and they say Yup looks like you need an AL24-F60. Palm Face Emoji. So we call up Spruce and after a long runaround I get customer relations and I say Can you go back there and get an AL24-F60 off the shelf and send me a picture of whats in the box? At this point I had the drawing from Hartzell detailing every part of the installation. The guy at Spruce tells me that the AL24-F60 is in fact what I need and it does in fact come with the installation hardware, but he says I will need to buy the correct tensioner arm separately because it isnt included in the kit Thankfully they sell that separately! I say OK go ahead and expedite shipping on both of those. Thanks. It shows up and what do I get? Exactly what I needed plus an extra tensioner arm because the one that isnt included in the kit is actually included in the kit...So why such a long-winded story about my Alternator Diaries? Thats good question. Not really trying to beat up PlanePower. Just trying to disseminate information that might save someone else from paying their mechanic for countless hours on the phone and keep them from buying two extra alternators that they need to figure out how to return or keep or something. BTW, If you are installing an alternator on a C-172N with an O-320-D2J, The part you are looking for is an AL24-F60. I could have had this plane done a week sooner!

Advertized as a kit led me to believe I was receiving an alternator, brackets, over voltage relay and regulator. Since picture of kit mentioned variations from picture I went ahead with order. Telling my customer what I expected to charge him took some later explanation.

I would have given this a 5 Star Review,,, BUT the through Bolt came from the factor non-threaded.... as it missed a machining step. The alternator does supply power at the low end much better that the previous Kelly unit. If not for the bolt issue, installation would have been really fast, even in a Mooney! If you look at the picture depicted there ARE THREADS on the bolt. Makes me very concerned about their quality control.

Bought to replace on my mooney m20c ....would not call lightweight only .50 pound difference....

For my 1980 172N, this did NOT fit properly with the existing stock size belt. The mounting brackets had to be slightly modified to allow enough space for the belt to slip over the pulley. Also the picture shows a new bolt and nut for hardware thats supposedly included, that did not come with the kit either. What should have been a one hour job turned into an entire days work. Not impressed.
