Avoid them. The will take your money give you the run around and then send you shit that will malfunction, charge you for the repair and take half a year to fix and return it even if they do that. This company is a joke ran by typical FL man. read more

I have a lot of amateur radi equipment i my Hummer H3. The total current draw from the radios and amps can be 180 amps. I installed 2 Odyssey PC1500 batteries and had him build a 14.4 vdc alternator at 300 amp output. It works perfect. The Odyssey batteries are 13vnc instead of 12 volt so the charge voltage needed to be raised. The engineers at Odyssey recommended the 300 amp charge rate. I also purchased a 20 amp charger from Odyssey to condition the batteries. Since doing this, there have been no problems with any of the charge circuit and after 2 years there is no discernible degrading of the batteries. I checked the current output capacity and it has no problem in providing up to 285 amps. This is about all the computer actually demands to keep up with high current drain which is seldom. Most of the time I only use about 120 amps current draw while on HF and using a 500 watt rf amplifier. I regularly check the output with a portable Fluke 199c Oscilloscope and see good clean DC voltage with no noise even while high current demand. I do this because I have over $20,000 worth of radio equipment that needs proper and safe voltage. I have never had any damage to any of my equipment . I don't know what the other reviews experienced with their alternators but mine has worked flawlessly. Robert S. BSME MSEE Member IEEE and ASME EXtra Class Amateur radio operator. read more

I emailed to get some info on what kind of alternators they sell (as far as output, electrical connections, etc). I got an email back calling me an idiot for asking that question and informing me that my email is being blocked so I can't bother him anymore... How does a company even function like this? I'd hate to see how he handles warranty claims or customer complaints... read more

There is only one other review, and look its a 1 star.... Believe it or not, its literally the same thing I want to write, but I rather keep it short. There is no Fictitious name filed in the state of Florida under Excessive Amperage. Go with a reputable company! The guy sold me 3 alternators with a regulator, that could have blew up my van, had I not disconnected all my equipment prior to installing. I gave him a video and a schematic of how I connected everything exactly the way he said. I have worked in the electrical field for just as long as he has built alternators. Customer service sucks, he told me to take the 3 alternators to a alternator specialist, but why, aren't they new? I asked him for figures, at least 5 times to test myself. But wait why am I doing this, aren't they suppose to work? He never once could say I connected anything wrong. Lets see Field, goes to the back of all 3 alternators, + is a switched on GND is GND. Oh I know what I did, I connected the F to + then I put a GND on F and then F went to the + of the battery, then the + of the battery went to the F connection on the back of the alternator. OMG I connected it wrong, he was totally right! He also told me not to fuse the regulator, or the field wire. Even though the regulator is in the cabin. I fuse everything! General Motors fuses everything! Its cause the colors of the fuses create this cool color effect which attracts hippies. Why would he deprive me of this? I been cool, haven't dropped sarcasm, or F bombs on him, but he still treated me like dirt. I made it clear I just want this work, no help form him at all. Also I disconnected my amps, and caps though he said not to. If I took his advice, smokey the bear would have popped up and said, "only you can prevent van fires". When the alts kicked on, it shot out 17V, the caps and amps are only rated to 16 MAX. Even the batteries shouldn't go above 14.7. After turning the van off and on several times to see why I am getting over voltage, the bridge rectifier on one or more of the alternators blew, smoke was pouring out, and it made a very very loud noise. One concern I had, the alternators he sent me were in a small housing, with smaller pulleys. Each weighed about 15lbs. The one he dynos on his YouTube video has the standard housing which typically weighs like 20/25lbs. BTW I asked him what his phone number was so I can talk to him vs messaging him on Instagram, and he ignored me on that. read more

Installer from last reviewer. Yes the batteries were disconnected, and everything despite what Nathan is saying. Btw love how on his website it says he's done this for 18 years, then on Instagram he posts 25+ years. Apparently he's sold thousands of alternators. As Anish said he doesn't doubt you make good alternators or functioning ones. This guy doesn't have a business license and this is based off his fictitious name filling, there is no company in Santa Rosa of county with that name filled by that could be found by either of us. This also means this "business", could not be insured. Meaning had the customers van exploded, is he ready to pay for damages? I was also just informed that like the other guy that posted on his review, you also are petty enough to sign someone's email up with a bunch of spam. You really are a child. Did the dispute come through is that why? PS he ended up buying it from another company which uses the same regulator. And using the same wiring and installed the same exact way, isn't it amazing when everything works the way it's suppose to? I don't use Yelp to leave bad reviews. Just an FYI read more

This is, without exaggeration, the WORST company I have ever done business with. This is a one man operation. I ordered a high output alternator for my car. I installed it and it was defective. No big deal. I figured I'd contact the guy and get it straightened out. After FOUR phone messages and FOUR emails to this guy Nathan, No response. SO, I contact him through PayPal and VOILA he responds back and says that he never receive my voicemails an emails. So, I tell him VERY NICELY that the alternator is defective and that I had an ASE Certified Master Mechanic check it out. He was irate in his messages on PayPal. He went on and on about how hes been doing this for 20 years etc All I asked him at the end of my email about the problem was "What should I do"? He became an animal. so, PayPal ruled in MY favor to refund my $350.00. I then start getting TONS of emails from Gay web sites. .Coincidence? Hmmmm. He then sent me a NASTY email via my regular Email account instead of PayPal and wouldn't stop bashing me telling me to get a new car etc etc etc. I then post a review of him on the Better Business Bureau website. They sent me his response which was that he never heard of me and never did business with me LOL. So, the BBB asked me to send them proof.. Which I did. He ALSO stated in his email to me that he would make CERTAIN that no one in his field will ever do business with me He also called me all sorts of names etc. He was like a child having a tantrum. Anyway, STEER CLEAR. I've been doing business with people over the internet since its advent. I build, repair and maintain high end computers for a living. I've NEVER dealth with anyone like him before. By the way, he's in cahoots with GP Audio who sent me a BASHED UP alternator and I had to get PayPal to refund their money a well. As it turns out, they are FRIENDS on FACEBOOK. Wish I would have known that sooner. Steer clear of Excessive Amperage and GP Audio. Don't say you weren't warned . read more
