if you're looking at the tisco kit, yes it comes with the 1-2 plug for voltage sense and charge enable (lamp wire) Dell is 100% right on the rpm issue. either you use electricity on the 1-2 plug to enable the voltage regulator, or you spin up the engine to use the residual magnetism in the alternator's rotor till it's fast enough to get the VREG going. Good luck

K..... ...you are very perceptive, the popular Delco 10-SI alternator comes in several versions which I call the 3-wire (which uses the 2-wire terminal plug) and what I call the deceptively desireable 1-wire version (which usually has a dummy plug installed over the 2-blades)

I'm not a big fan of the 1-wire version because you haffta jazz yer cold engine to about 1800 rpms before the alternator kicks in and starts charging. This is fine for most other automotive/marine conversions 'cuz their engines run at higher rpms than our 2200 rpm max N-Tractor engine.

The 3-wire version starts charging at about 500 rpms, GM likes it 'cuz thats the way they install'em on their Chevy's. Its just more complicated and uses an idiot light scheme.

As to wheather the "kit" uses the 2-wire plug, depends upon the kit I guess. I don't make'em, I just help the electrically challenged fix their mistakes.

I'm a 12 volt advocate for the right reasons. That said, I haven't found the right reason for my eazy starting 52 8N, and I know how to do it right. Infact, I know 7 ways to convert N's to 12 volts and they all work. Remember the 6 volt mantra: "keep'em clean, bright, and tight"..... ....Dell
