jimmyZ Posted March 5, 2008 Report Share Posted March 5, 2008 sucks because I just found out this afternoon that my 20 & 24 year old girl cusins :D that I have never met (from alaska) are at my mom's and she wants me to come over and meet them before they fly home tommorrow morning. But I'm broke down, and my boss was hesitent on me bringing my worktruck home (and I don't beg) because he thinks I'm going to drink and drive or something, I don't know, even though I can drive it for work a hundred miles in a day for work. I've been with him less than a month, but what he doesn't realize is I have a better offer hitting me up, that I applied for when I got this job, and I'm starting to feel less guilty about considering it... Anyway, I did get it started right before I left and it was not charging, died when I pulled the neg. cable. As I said before I only have the one wire going to the alt. and that is the spliced on that is white/black (pictured). Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 This is for a for a 77 280, but the female harness,, the one that goes TO the regulator,, has the same wiring, for reference: http://www.zcarcreations.com/howto/voltreg.htm Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 OK, I just turned the key on and every wire lit up the test light except for yellow (and black which is not used correct?), that seems weird to me. Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 when I hook up white and yellow, it turns my ignition on. Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 ok, so now I'm going wht/red to wht/blk, and white/blu to yellow (the method on the page I linked). My ignition is now responding to the key properly, but still no charge (I think I may have burnt the alternator trying to run it through the regulator), so I switched to the blade connector at the bottom of the "T" on the alternator and my charge light (dash) now is on when the key is off, and off when the key is on. I'm thinking I've got it right (with the wire back on top of the "T"), but it's a suicide run to autozone to get the new alt. ...but maybe I will run it and buy the new battery also (sucks) so that I can get home on it's power if it doesn't work out. Not to mention having to R&R this thing in the parking lot in the dark. heh any thoughts? Dattymike you out there? I'm going to keep your hookup in mind in case this one doesn't work. I definately know that white to yellow is no good though, because as I said, it turns my ignition on (permanently). Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 Quoted from the other thread just for reference: It should also be noted that my white/black has been spliced before the female end (that connects to the regulator plug) and runs to the alternator, the only wire that was hooked up to the alternator, (I don't even know where the other end that goes into the harness is)and I believe it was hooked up to the post marked "Y" on your graphic (top of the T) but I'm not sure (it may have been hooked to the other post, I know, I'm a mess). because I'm not sure that the blk/white is SUPPOSED to be run to the alternators "T", although it did charge that way before, but I'm just not sure that this is not the problem that is causing the trouble.

jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 Oh yeah, and btw, notice the yellow wire LOOP in the first pick? Looks like tampering to me, because those wires do not look like they started out hooked to each other, so... but like I said it was at least charging before... Quote Link to comment
BEEBANI Posted March 5, 2008 Report Share Posted March 5, 2008 Wow, A.D.D. much!?:blink: Go to http://www.the620.com they have wiring diagrams on there. Quote Link to comment
datzenmike Posted March 5, 2008 Report Share Posted March 5, 2008 Oh man... that's a nightmare. First... Do you have the original truck plug??? the '77 Z car plug uses at least two different color wires than the truck one. Looking into the Z car plug start at 12 o'clock and go around clockwise and tell me the colors of the wires. The plug has a notch to properly mate it to the female one on the regulator, start there and go around. Cousins from Alaska??? 20 and 24??? Why are you messing with wires ... get home!!!:D:D:D Quote Link to comment

Yeah, it is the original plug (got to be) ...what I am saying is that the colors do line up the same as that Z's though. so it's: 1 white/red 2 white 3 yellow 4 black 5 white/black 6 white/blue ...the only reason I haven't made the suicide run yet is because I am dead on my feet and I'm trying to work up the strength/will, also wish I was a little more confident about my bypass.

BEEBANI Posted March 5, 2008 Report Share Posted March 5, 2008 I was just giving you a hard time for the minute by minute posts! Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 Ok, so my mom just told me that the one cuz is pregnant (I asked if they were "chubby" LOL), but the other is really cute and tiny, she said she probably weighs 90 lbs. :eek: LOL. Oh and supposedly while they were in Vegas, before they came here, they had a few drinks with my uncle who was also there at the time(assuming not the preggo one), ...so apparently she parties. heh. btw, most of my cousins are really hot, so... (not that I'd do anything weird or anything ;)) this sucks... Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 I was just giving you a hard time for the minute by minute posts! yeah bro, I'm frantic here... and running on fumes... Quote Link to comment
jimmyZ Posted March 5, 2008 Author Report Share Posted March 5, 2008 well, I'm going to jump in the shower while I'm waiting for any ideas... 8:30 pm over here in Cali. I found out also that they don't leave until 5pm tommorro, and I'm thinking about telling my boss I need a day off to fix my truck... Quote Link to comment
datzenmike Posted March 5, 2008 Report Share Posted March 5, 2008 so it's: 1 white/red 2 white 3 yellow 4 black 5 white/black 6 white/blue . Perfect, that agrees with my wiring diagram for the '77 620 truck. OK: Just take the connector and jumper the White and Yellow wires together, then jumper the White/Black wire to the White/Blue wire. That should do it. (at that end) You still need the connections at the alternator including the T shaped plug. The A terminal (White wire) on the alternator, goes to the + battery terminal. The E terminal (Black wire) on the alternator, goes to ground. The N vertical terminal (White/Black wire) on the plastic plug, goes to the regulator plug. The F horizontal terminal (Yellow wire) on the plastic plug, goes to the regulator plug. Quote Link to comment

When I put the white and the yellow together the ignition turns on ...and stays on... it's not right. so, I'm going to try the way I got it wht/red to wht/blk, and white/blu to yellow, and right now I'm going to make the autozone run. I finally got the time to do it. my boss came around the next day about me taking the truck home (actually kind of an interesting story, and I do mean "kind of", so I'll spare you), and I did meet the cuzins for a brief period, although not exactly my hottest cousins, they were sweet. And the one did say she would send me some fish :), so... But not going to be able to trust my mom's call on cuteness so much anymore though LOL, she's usually pretty acurate (usually non-cousins, you sickos, heh). Quote Link to comment
jimmyZ Posted March 7, 2008 Author Report Share Posted March 7, 2008 finally got it. 1:15 AM... Just one wire though (wht/red to wht/blk, or just wht/red straight to the alternator in my case), but it's charging, and interestingly enough, the idiot light seems to be functioning correctly as well. Tired now, must sleep, work tommorrow... thanks again for the help guys. I'm going to try to figure out the other wire later (if I even need it). Quote Link to comment
banzai510(hainz) Posted March 7, 2008 Report Share Posted March 7, 2008 this is a a 510 xternal to internal volt reg swap. alot of datsun cars/trucks use the same colors wht/blk to wht/red is correct http://datsun510.com/photopost/showphoto.php?photo=124&size=big&papass=&sort=1 Quote Link to comment
