Searched the forums but couldn't find all the info I am looking for. I'm doing the swap using a bracket from NPD and a Delco 10Si 63 Amp 1 wire alternator. the alternator is readily available where I work and for 80 bucks CAD I couldn't go wrong. My question is, How do I hook it up and what wires from my Harness (voltage regulator) do I snip / get rid of?
My understanding is the wire off the alternator goes to the battery and it gets it's ground through the case, and a "signal" wire runs to the starter relay on the firewall? am I close? haha
Pictures and small explanation would be a major help!
Thanks in advance
Sounds like your 10si is not a 1 wire unit if you are asking about more than one wire. I prefer 3g alternators over 10si for reliability but make sure you convert your 10si properly to 1 wire use.
The "poor man's" one-wire 10si is made by connecting the terminals labelled 1 and 2 gashog's drawing. You have to rev it up a bit to get it charging but it will work.
I have a 10si in my ‘63. The generator light works. I did the swap 30 years ago and cannot remember exactly how. It is also wired so that it doesn’t need an RPM tickle to get the charge started. My dad had a friend that had an auto electrical shop in Hollywood (Wolford or Woolford Auto Electric) when I was a youngster, the guy told me over the phone how to do it and I wasn’t smart enough to document the instructions. I used the original wires and taped the loom. I remember having to change gen brushes periodically and I remember charging issues in rainy weather.
I did a 3G swap in my ‘72 and converted the alt gauge.
