Electronic ignition upgrade / voltage regulator question

Thankyou very much Dave. You guys are great. The only reason I asked is because I am STILL having charging problems. I had my alternator rebuilt, purchased a new regulator, mounted all and made sure grounds were very good, started her up and guess what, 17.5v! And get this. I had her charging great at 14.8v before I done all this. So I made temporary wiring and bypassed all original wires, still the same. The only thing it pointed to was the new regualtor was bad. Put my old reg back on, 14.8v. Reinstalled the new reg, 17.5v. Put old reg on again, 14.8v. Took the new reg back to the alternator rebuilder, they tested it and sure enough it was bad. They replaced it with another new one. Scared to death to try this new one. If this gives me trouble, what the f$*^ am I supposed to do ? Talk about sh&* house luck!! Sorry for the rant. I want to trace all wires, so this is why I asked where the Ign 2 wire went. Thanks again, really appreciated, Keith.
