datson4life Posted May 24, 2013 Author Report Share Posted May 24, 2013 and ive been using autozone regulator...............they suck+me messing up = Quote Link to comment
banzai510(hainz) Posted May 24, 2013 Report Share Posted May 24, 2013 i didnt tighten the neg and positive to the alt, i beleive thats why i messed up the last 2 regulators Thats most liekly it. The Autozone regs are fine. They are made in USA by Wells. carquest sells them also. I like them myself. Quote Link to comment
datson4life Posted May 24, 2013 Author Report Share Posted May 24, 2013 started the truck this morning and now its at 16 volts........what voltage is too high? Quote Link to comment
izzo Posted May 24, 2013 Report Share Posted May 24, 2013 16 is def too high. 14.4 is about right, maybe a little more... At least in my experience. FYI. Before I knew about differences in alternators, i installed an internally regulated alternator on rig that still had the external hooked up. it got high voltage light that, and even higher.. Not saying that's your issue, but was mine. two wires and 4 spade connectors i was good 2 go Quote Link to comment
banzai510(hainz) Posted May 24, 2013 Report Share Posted May 24, 2013 too high get another volt reg this is what mine did when i popped it after not haveing the connections tight before starting it up. I have a stack of volt regs Mybe try a mechanical oVR ,maybe they less prone to voltage spikes as they use points in stead of circuts. But I had bad luck with the NAPA Echlin/neihof brand ones. datsunaholic mentioned the correct alternators in post #42 Quote Link to comment
datson4life Posted May 24, 2013 Author Report Share Posted May 24, 2013 ok, im gonna leave it alone for a few days but when i get back ill continue, thanks for all the info thanks banzai510, just realized the posts are numbered on the right top corner Quote Link to comment
datson4life Posted June 4, 2013 Author Report Share Posted June 4, 2013 ok, so the regulators blow when i rev high and get on freeway, im on like my 5th regulator, the alt has been tested and its "good" (autozone) im going internal regulated alt, i got the wiring figured out except for the T plug that goes to regulator, what do i do with that? :confused: Quote Link to comment
banzai510(hainz) Posted June 5, 2013 Report Share Posted June 5, 2013 T plug that goes to regulator, what do i do with that? What does the instructions say to do?????????? Nothing.with the T just make the 2 jumpers, plug the T in, thats it. Hope you dont pop the internal reg in the alternator. its Ezer to swap a externat volt reg than a Alternator out every time. to me this shows soemthing wrong with GROUNDING ISSUE OR A WIRE GOING BAD OR SOEMTHING SINCE YOU DID THIS WIRE TUCK Quote Link to comment
datson4life Posted June 5, 2013 Author Report Share Posted June 5, 2013 i didnt know the internal regulated alts came with a T plug :blush: Quote Link to comment
datson4life Posted June 5, 2013 Author Report Share Posted June 5, 2013 swapping it out right not for a later model z car alt Quote Link to comment
oldskoolvws Posted June 6, 2013 Report Share Posted June 6, 2013 Carlos...listen to hainz. You likely have another issue (although going internal is not a bad thing). You should figure the problem out first and then do your change over. If your certain its the alternator, swap it or borrow a known good one to prove. If you don't you can just compound issues which would make it more frustrating. Quote Link to comment
kelowg Posted June 6, 2013 Report Share Posted June 6, 2013 Maybe 510 and 521 reg wiring is different. U said the new one was spec'd for 510,correct? So what reg r u using. Quote Link to comment
banzai510(hainz) Posted June 6, 2013 Report Share Posted June 6, 2013 YOu never know it might fix it doing the Internal reg alt swap. I seen weird things happen. Maybe the jumpers(shorts) are in the wrong spot. Some people use the old volt reg wires as the jumpers.So I cked out my old USA mecahical volt reg. the wires were the right color but plugged in the wrong spot. so when you plug it in the engine harness it would be wrong. so alwasy ck the engine harness side for the correct colors.

datson4life Posted June 7, 2013 Author Report Share Posted June 7, 2013 i threw on the original old alternator that came with truck and its been working pretty good, i didnt have much luck with the internail swap, i will continue the internal regulator swap next week, Quote Link to comment
datson4life Posted June 7, 2013 Author Report Share Posted June 7, 2013 the wires i jumped on the regulator plug for the IR were the yellow and white/red one, thats how kelowg has his and his runs nice, why cant mine :crying: Quote Link to comment
DanielC Posted June 7, 2013 Report Share Posted June 7, 2013 "the wires i jumped on the regulator plug for the IR were the yellow and white/red one, thats how kelowg has his and his runs nice, why cant mine :crying:" I would guess this is your problem. You probably shorted something out when the wires were moved outside the inner fender. Quote Link to comment
banzai510(hainz) Posted June 7, 2013 Report Share Posted June 7, 2013 i threw on the original old alternator that came with truck and its been working pretty good, just eave it along now call it good. Quote Link to comment
datson4life Posted August 25, 2013 Author Report Share Posted August 25, 2013 ok, here whats been happening, i used the old alternator and worked fine for a good while, so because of my grounds being pretty lame i messed that one up, ok, made better grounds.......finnally today got a new subaru alt 60 amp internal regulated that fit right in, installed it...the only wires i jumped when i took regulator off were yellow and white/red on the regulator plug, i am getting 12v when ignition is on in one wire from alt T plug problem: not getting more than 12 volts when i start the truck, its not charging question: do i need to jump any other wires on the regulator plug other than yellow and white/red?

datson4life Posted August 25, 2013 Author Report Share Posted August 25, 2013 is that a 521? Quote Link to comment
datson4life Posted August 25, 2013 Author Report Share Posted August 25, 2013 ive seen this, post #13 datzen mike jumped yellow to white and white/black to white/red but i beleive that is for a 510 http://community.ratsun.net/topic/19451-ir-alternator-swap-help/ Quote Link to comment
wayno Posted August 25, 2013 Report Share Posted August 25, 2013 That is how my 521 is wired now, I have an internally regulated alternator, actually for several years now, it came out of a early 80s 720. Uncle La La is the one I copied, his also was a 521. Quote Link to comment
wayno Posted August 25, 2013 Report Share Posted August 25, 2013 is that a 521? It may not look like a 521 with all them wires, but it is indeed a 521. Quote Link to comment
datson4life Posted August 25, 2013 Author Report Share Posted August 25, 2013 which wires did u jump to make it work????, looks like a couple jumps Quote Link to comment
wayno Posted August 25, 2013 Report Share Posted August 25, 2013 It's so dirty in there, I will go look. Quote Link to comment
