I can't speak highly enough about the customer service Luke provided. I was having issues with my 3rd gen Cummins alternator/voltage regulator so I purchased a... read more one wire alternator from Hagemeister. I needed it immediately to head out on a hunting trip the next evening so I had it shipped UPS Next Day. UPS dropped the ball with shipping and Luke called me first thing in the morning to let me know that it looked like it wouldn't be delivered that day and that he had already filed a claim with UPS. I returned from my trip to find the alternator at my house. It was well packaged, fit perfectly and immediately cleared up my charging issues. Luke refunded the shipping charges for me since the alternator did not show up as scheduled. Thank you Luke and your team for the excellent customer service. You're on the short list of companies I'll recommend without hesitation!

The best alternator ever for my old truck

awesome, I've just watched the videos but I'd say these guys know what they are doing

IT IS FIXED! I have had a charge problem with my 03 f250 7.3 for soooo long. I kept trying to figure out the charge problems. This... read more one wire alternator was the solution. The cursed exciter wire is shorted out somewhere other than the usual places. I was not looking forward to trying to chase that problem. Was considering selling my truck, or buying the whole wire harness, yikes! Then I found Your YouTube channel and ordered the alternator for my truck. Now, I have 14.4 volts at idle! THANKS FOR ALL YOU DO! I'M KEEPING MY TRUCK!!

Took my boat out on the lake and couldn't get it to start, pulled it out of the water and drove it to town and stopped by... read more their shop. They didn't hesitate to stop what they had been doing to take my starter out (which was in a terrible location), test the starter and get a new one installed at a great price and even better customer service. We got back on the water that day. Top notch customer service and I wouldn't take my vehicles anywhere else.

Purchased a stud for a starter motor that solders onto the fuel coil windings received it in short time exactly what I was looking for fast service... read more and great price

Hi I bought this 12 v alternator for my Model A . Sounded that they charge at low RPMs the Model. A RPM is suppose to... read more be 450 rpms ,much to low for an alternator ,Put head lights on your in the Negative . Kinda thought they made it magic my fault for not asking what is low RPMs. Runs well set up pulley with the new belt work well at 600 rpm

I had a problem with an alternator I purchased. After talking on the phone to do some long distance troubleshooting (which will be helpful) they’ve agreed to... read more warranty the part if necessary. I appreciate that kind of customer service

I know next to nothing about cars. I was recommended to HEI after getting a battery replaced and finding out the clamp on one of the... read more battery terminals wouldn't tighten enough. HEI was able to look at my car same day, and even better were able to fix it same day at a very reasonable price. I was able to watch the repair and they explained exactly what they were doing as they did it. I highly recommend them.

I’ve been having some electrical problems with my Lincoln MKC that other local businesses were not helping me with. Hagemeisters listen to the issues I was experiencing... read more and decided that a new battery was the easiest place to start. So far the electrical issues have been resolved with a new battery! I honestly have no idea that Hagemeisters even carried batteries in the shop! Highly recommend!

Overall, so far, so good. Ran into a couple glitches along the way which might be good to add to your instructions. #1: Do not use a... read more battery isolator or any other device that blocks the alternator from having battery voltage applied the alternator. #2: If you have an automatic, you will need to reposition the transmission coolant line slightly to clear the back of the alternator. The only other thing I can suggest is putting a ground stud on the alternator case. Dodges are notorious for bad grounds and having to use the brackets is problematic. 1992 Dodge W250.

Luke is always courteous, professional, and gets the job done the right way. Highly recommended!

Bought a gear reduction starter for my jd 630 fit great and never started better.

My alternator failed on my Ford Powerstroke and the team at HEI rushed a new and improved version of the 200A to me so I could get... read more it installed. Great guys. Thank you for the hat , I proudly wear it.

Great place to find parts for older electrical systems. Knowledgeable staff.

Great guys. The old man really knows his stuff. Good prices too.

Worth every penny! I tried the rest and finally found the best. The Hagemeister One wire alternator solved my charging issues. Stop wasting time and money on... read more Chinese voltage regulators that can potentially burn your truck down. (Ask me how I know) The quality of this alternator and personal service is top notch. You won’t be disappointed .At idle I get 14.3 volts with lights, Ac and radio on, and it stays at that voltage at all rpm’s . 1995 Cummins swap

First off, I'm not a mechanic of any kind. After watching a YouTube video I was willing to attempt a starter replacement on my truck. ... read more Hagemeister was awesome. Everyone I spoke with was very friendly, patient, and helpful. They did everything possible to get me the right part and answer my questions. Shipping was fast. I got it installed and the replacement part cranks my 7.3 Power Stroke Diesel better than the factory starter ever did.

Great prices and knowledgeable.

These are the "Go To" Guys. Love the Expertise !!

Been doing business with these people as needed for over 30 years.....most helpful....and LOCALLY OWNED AND RUN

I have used HEI to check or rebuild all my generator's, alternator's and starters for 50 years! Trucks, cars, tractors, RV's or my snake river boat HEI... read more checks them all! Until recently that was all I used them for. Then Larry introduced me to an oil product called IXL. I was a lube tech in industry with mechanical apprentice and have been to many continuation ed. classes on oil. I'm very aware of the so called "Miracle Products" available that fix everything. I remember thinking, "whatever" when Larry asked me to try the oil and give a review if I liked it. I have a Pacific Energy fireplace insert and the blower motor quit working. It "wouldn't turn" and of course when I tried to order a new electric motor I was told it was no longer available so I vacuumed all the lint and dust out of the windings. That's when I noticed oil ports to the bushings. I put a drop of IXL in each bushing port and slowly began by force turning the fan/motor housing for a few minutes then added another drop of oil. After 30 minutes of slow turning by hand it began to loosen and turn freely. I reinstalled the blower, started a fire and waited for the heat sensor to heat up and turn on the fan. It's been run for a week now and even running quieter. IXL is going in the next oil change on the 2003 Ford 7.3 diesel. The 7.3's have an injector issue called "Stickion". I like what IXL does for a frozen electric motor! Lets see what it will do for my ol ford! Honesty, Integrity, Sound Advice and Great Service is what you get everyday at Hagemeister's! Thank you, Larry, Helen and Luke!
