Moisabamf Posted January 11, 2009 Report Share Posted January 11, 2009 i have the light down, but do i run a wire directly from the starter to the "S"? or could someone explain this harness better Quote Link to comment
ggzilla Posted January 11, 2009 Report Share Posted January 11, 2009 (edited) So the left side of the diagram is for the internally-regulated Datsun alternator circa 1980 type. * Don't run any new wires to the new alternator, plug in the original T-connector to it * pull the connector off the original regulator, and add the jumper wire. If you have removed the original wiring, then you have to figure out what to do next... Edited January 11, 2009 by ggzilla 1 Quote Link to comment

Phlebmaster Posted January 13, 2009 Report Share Posted January 13, 2009 (edited) Could some one please post a picture of an actual alt in the car and show the wiring set up on this? I will be doing this same thing with my 620, I got a 65 amp alt to put in and I would like to see it done right so I don't mess it up. Thank you very much for this post! :D Edited January 13, 2009 by Phlebmaster Quote Link to comment
banzai510(hainz) Posted January 13, 2009 Report Share Posted January 13, 2009 Nothing to mickey mouse. Just in trucks bigger alt could hit idler arm. remove ext reg just get jumper wires and install it where the plastic connector when to the reg. use the color code on the datsun wire harness not the regulator as some newer regs had right color code but not match up to the datsun pin wireing. this is for a 510 but color codes are the same I believe http://datsun510.com/photopost/showphoto.php?photo=124&size=big&papass=&sort=1 Quote Link to comment

I can't wait to get this done. :D There are sooo many threads on this but I have not seen a clear pic of the wiring after the install. That is why I asked. I will take one when I install mine. ;) Quote Link to comment
ggzilla Posted January 14, 2009 Report Share Posted January 14, 2009 (edited) Could some one please post a picture of an actual alt in the car and show the wiring set up on this? Here ya go: 1. Pull regulator connectors apart Ratsun types will add jumper: Trailer queen types will need this store-bought jumper, only $30 I've got no pic of the alternator, because it was just stock. I fitted newer engine with stock IC alternator, into older Datsun with external regulator wiring harness. The newer IC alternator uses the stock wiring harness in a 510 or B110. Same connectors and everything. It is an Hitachi IC internally regulated alternator. Subie alternator shown below fits same brackets, but electrical connector is different.

banzai510(hainz) Posted January 14, 2009 Report Share Posted January 14, 2009 ggzilla Exactly!!!!!!!!! you need 2 jumpers in the photo. people might get confused only seeing one Quote Link to comment
Pacific coast Datsun Posted January 14, 2009 Report Share Posted January 14, 2009 (edited) Aaron i swapped in a 77-81 65 amp 510 alt last year. Easy, remove voltage regulator from truck...cut 2 wires off the plug & extend them & connect to the T plug that goes to the alt.,[forgot the color of the 2 wires u cut-im old], youll need a new fan belt too. Can get that # today & post. Heres a pic after i ran the 2 new wires...seee upper R of pic connectors]...finger is next to the 2 i cut & extended... a better pic of the wiring & i also had to zip tie the lower rad. hose out of the way...& it clears the idler arm by 1/2 inch or so... & the 2 alts....cost $75 @ Kragen [shucks]... Edited January 14, 2009 by Pacific coast Datsun put same pic up twice..doh! Quote Link to comment
hang_510 Posted January 14, 2009 Report Share Posted January 14, 2009 Here ya go:Ratsun types will add jumper: :lol: i used the jumpers to confirm functionality, then took apart the connector and soldered all the conections. now it looks stock :D Quote Link to comment
ggzilla Posted January 15, 2009 Report Share Posted January 15, 2009 you need 2 jumpersDid I miss one? I only used one. The alternator T-shaped connector only has two wires. One for the dash Lamp, the other for the on/off IGN. My jumper is for the latter, but the dash lamp worked without a second wire. Quote Link to comment

ggzilla Posted January 16, 2009 Report Share Posted January 16, 2009 Well I foisted mine off on Icehouse, sold him the whole car. On my own Datsun I run a 35Amp alternator. Quote Link to comment
