I figure I'd combine 2 subjects since my questions are electrically related.
1) I picked up a rebuilt HEI distributor and am converting the car from the Points Type Ignition. I've read the archives and just want to confirm. All I need to do is trace the Positive (+) wire on the coil to the fuse block, replace that wire with a 12 gauge wire, and hook the new wire to "BATT" terminal on the HEI. Hook the "TACH" wire on the HEI to the tach. Done deal?
2) I picked up a 100 amp 1-wire alternator. I've read other sites on line as far as the connection. Most say to hook a 10 gauge wire directly to the Positive (+) terminal on the battery or the Battery terminal on the starter. Which is the better option? Now some are also mentioning putting a fuseable link in between the Alternator and the Positive (+) terminal. Is this correct and if so, what amp fuse?
3) Since I now have an internal regulator in both of these systems, do I disconnect ALL the wires from the old Voltage Regulator on the firewall and chuck it? Shall I just leave the old unsused wires tucked away on the harness?
1) I found the stock coil wire (blk/prpl). Now how do I actually get to the wire connection on the bulkhead connector? Do I just pry the spade connector out somehow? Do I use 10 or 12 gauge wire?
Off-topic question on Starter Wiring. Where does the purple wire from the bulkhead connector connect to the starter? Which post exactly?
You have to unplug the harness. There's a really fun bolt in the middle you have to loosen first. You can then use a screw driver to get the one spade/ wire out from the inside of the bulk head connector. Don't think that black goop is bad Keep it in there - it's dielectic grease and prevents moisure from destroying all the connections. NAPA sells the spade you need which you can then connect to the new non-resistance wire that will go to the Batt terminal on the HEI. I used 12 gauge.
There used to be a COLOR wire diagram out on the web somewhere that was invaluable when I was doing all the electrical stuff. I printed a copy that is on the wall of my garage. I don't have the file or URL though. Someone here might remember where it is.
That's the one! Awesome. So from that diagram you can see that the big fat wire from the harness goes to the same terminal on the starter as the battery cable. I just put in a new starter a few months ago DOH! and can't remember if it's the S or R - but S sounds like the right one. R is not used with the HEI. Someone correct me if I'm wrong
I've searched "Starter Wiring" in the archives here and on CP and I'm getting mixed responses regarding the S and R terminals. Most are saying that the purple wire from the bulk head connector connects onto the S terminal. And the battery cable connects to the big stud on the starter. If you have HEI, the R terminal is not needed because it was previously used as the wire that supplies 12 volts to the coil during starting in points-type ignitions. It's kind of funny because the original 69 diagram linked above doesn't how the coil in points-type ignitions gets the 12Vs. It shows the blk/prpl wire from the bulk head connector as the resistance wire to the positive side of the coil AFTER starting and DURING regular running. I'm just curious but how does the coil (points-type) get it's full 12Vs when you try and start the car?
