Easy Classic Ford Upgrade
I bought this to beef up the original electrical system on a '66 F100 so I could reliably run a large electric fan. I didn't want to chop up the harness for a 3G or 1-wire modification, and I don't plan on running any other electrical accessories besides the fan, so this fit my needs. Powermaster is a well known and respected brand in the automotive aftermarket parts industry and this alternator definitely lives up to those expectations. Installation is no different than swapping a stock alternator and it works with the original mechanical regulator too. With a Flex-a-lite 180 fan rated at 3,300 cfm and drawing 18 amps, plus all the other accessories on, voltage at idle is still over 13.5. I'm also running a Pertronix ignition with the resistor bypassed and the truck seems to run better and start quicker now since system voltage is a little higher at all rpms. Overall a fantastic value and a wise addition, even if your classic Ford is completely original in my opinion. Your battery will thank you!

Wire it EXACTLY like the previous one, don't get creative and move wires around
My 1965 Ford Thunderbird when I purchased it, turned on but sounded weak lights dimmed at night when I drove it, so I decided to change the starter, solenoid, and voltage regulator, then I purchased the Powermaster 7078 and installed it, had the battery charged at a local parts store installed that, now the car hums and has nutz! that alternator sure did the trick, electric windows roll up and down like the car was new incredible! Well worth the money, don't dick around don't buy the Chinese remanufactured trash to save money, buy a good quality American made product. Highly recommended.

Great Quality and Fit
Looks great and installs directly in the factory location. Power output is better than the original and uses the factory wiring and regulator for a stock-like install. I used it on a 1963 Thunderbird so I did have to modify the wiring slightly to make it work since the connections are different. This is probably more suited for a late 60s through 70s model wiring.

Outstanding product
Works like a dream. Fit and finish are excellent. I called Powermaster with a question on a Saturday, customer support was immediate, helpful, and friendly. Performance compared to the stock alternator is exquisite. absolutely no problems. FYI- Installed in a 1968 Ford F100 with a FE 390 V8.

Alternator sucks!
This alternator whines like crazy the first time I started the vehicle. The box came damaged and was probably dropped during shipping.

Well made but wrong pulley size
The alternator arrived in good time and was well packaged. During install, I discovered the pulled required a different diameter belt. Use of this alternator would require changing out the pulley, which would most likely void the warranty. I had to return and find a supplier that had the correct alternator & pulley. Application was a Ford Mustang with 289 engine. Taking off 1 star because of this.
