[ARCHIVED THREAD] – Wiring a Delco 10SI alternator – is the idiot light All of the wiring diagrams I have seen have a wire from + through.
We are commonly asked how to wire the Delco SI series alternators upon maintenance or upgrading from an older generator. While this series of unit often runs as a self exciting one wire, agricultural applications also used 3 wire connections to the alternator.
With key on power is. Operating principles and wiring diagram of 10Si and 15Si alternators. Page 2.

The 10SI has three terminals (including those with a 1 wire regulator). The large “BATT” terminal which gets connected to your battery.replacing a 20dn, 30dn, 41 dn, and d.c.

bearing in 10si; retrofitting old stlye delco remy regulator to new style delco remy 50vr regulator; rotor replacement.
Over the years many farm tractors have been fitted with the 10SI alternator. The kits that I offer use a new 63 amp Delco 10SI cloned alternator.
Each kit comes with a mounting bracket, tightener bracket, correct size pulley, diode/exciter wire, and wiring instructions and wiring diagrams. Apr 15, · I read all of the posts and found the proper wiring diagrams for a 3 wire 10si.
I installed a new alternator (3 wire internal regulator) in my ’62 comet. I wired the main lug on the alternator directly to the battery cable side of the ford starter solenoid.
I jumped post 2 from the 2 post connector to the main lug on the alternator. Apr 01, · I don’t think Delco ever made an OEM alternator that was designed for 1 wire operation. If you have a real OEM Delco 10si or 12si alternator, or equivalent, it should always be a 3 wire. However, if you have a Delco that was converted to 1 wire it would have a self energizing regulator.
Some other tidbits available from AC Delco for wiring up a 10SI, is wiring package (for those 6 to 12volt conversions). This contains the terminal connector AND an extra resistance wire pigtail to connect to the ignition system (don’t use a ballast resistor if you use a resistance wire).Gm Si Alternator Wiring | Wiring LibraryThree-Wire Delco 10SI/12SI Alternator Question – Hot Rod Forum : Hotrodders Bulletin Board
