I agree with Butch, my B&C with external regulator has given me 1400 hrs of trouble free service. You need to fix your high voltage issue before you “toast” your avionics.
B&C is the gold standard for alternators. Some dislike the separate voltage regulator but I think this is a plus as you can locate in a more vibration free cooler environment.
For a quick fix and to get back home would turning off the field via breaker or switch (provided you are getting over-voltage) work? Issues?
B&C hands down. Buy it, install it, and you’ll never regret it!

Thats a great price... Im guessing I would have to fabricate mounting brackets?
Well engineered many inspections and specifically made for A/C . yes its more money but you really get a quality product for the money , the external Regulator is bulletproof. With our planes so Electron dependent its good to spend the money where it counts

You might find that the alternator you need to replace is a common Nippon Denso automotive alternator, so the bracket will not have to be changed if you use the same alternator again.
You'll be back in the air for the best cost and time invested.
Next, consider adding a Monkworks alternator to your vacuum pad on the back of the engine and now you've got a back up and primary alternator working for the least amount invested if you were already considering adding a back up.
My Nippon Denso alternator was working great after 700 hours and 17 years of operation on an RV-7 I bought built. The builder had a back up alternator on the shelf just in case so I bought that one from him and still have it sitting there just in case.
Of course there's nothing at all wrong with a B&C and external regulator since guys here have been having great success with them.
Dan, the Plane Power EI60 is clearly marked but give us a picture to be sure. If PP is what you have then there are a couple of places to look that would increase voltage. Primarily it is in the field supply line. If there is any resistance the internal regulator will read that as a lower voltage and increase the output.
The most common issue is in the connector to the alternator, it is easy to check and repair. If it has an inline fuse, those can corrode and add resistance. Any other connector or switch should be checked too.
You could take it off and get the local auto parts store to check it for you. The B&C cost per hour is the lowest because it lasts the longest per a thread a couple of year ago. The field (then) seemed to be 1/3 each for automotive, PPEI60, and B&C 60 amp.
I have a PP with 250 hrs, and recently added a Monkworkz 2.5 lb 40amp back up.
Hi FLying Tiger,
Being a Department of Redundancy Department kind of guy, I like the idea of the back up alternator... do you know how much it weighs? Super Tweety is a big girl (meaning fattie) carrying a lil extra if you know what I mean.
Last time I had that alternator off, I looked for an identifying tab but couldn't find anything to tell me what make and model it is. Suggestions?
God willing, I will get out to the airplane tomorrow and check the voltage coming out of the business end of the alternator. And then know what Ive got to do.
