JMAGG Posted April 13, 2020 Report Share Posted April 13, 2020 Hi, I figured I would come here to see if I can get some help. I have a 496 BBC Gen V in my 1969 Camaro. I currently have a mechman 7127240 alt in it and have had nothing but problems with it. It is a single wire alternator. For some reason I've gone through 2 of these mechman alts, the first one did not charge my battery at all so it was DOA. Now the second one just randomly stops charging and the only way to get it to work again is if I disconnect everything from my battery for about 5 min then it will work again for a couple of days. I'm trying to ask mechman for help but they haven't gotten back to me. A couple people have told me that I may be hooking it up wrong but how can I be hooking up a single wire alt wrong... Also, my old 60 amp alt still works perfectly have only had problems with this mechman, wish I got a US alternator or something. Link to comment Share on other sites More sharing options...

JMAGG Posted April 14, 2020 Author Report Share Posted April 14, 2020 I have a volt meter in my engine bay. I uploaded a video of it not charging. Next pic shows the battery disconnected, then next video shows it charging again. Not charging_Trim.mp4 Link to comment Share on other sites More sharing options...

EricM9104 Posted May 17, 2020 Report Share Posted May 17, 2020 Where does your ground go from the battery? Does the motor have a good block to frame/body ground? As well as a ground wire running from the alternator bracket to the battery? 2015 Honda Civic LX 4dr | 24k miles Stock H/U and mids/highs Power Acoustik GW3-12" D2 Sub HiFonics BXX1200.1D @ 1ohm Random 2.5^3' dual ported box NVX LOC Stinger wiring throughout 1977 Chevy SWB Cammed 350 Dual exhaust Cheap Wish stereo Link to comment Share on other sites More sharing options...
