Delco 10SI 12SI 15SI 27SI self exciting 1 wire voltage regulator 13.8 D10SE138

Description

1 wire, self-exciting, 13.8-volt, voltage regulator for 12 volt systems.
This is the voltage regulator you need to turn a standard 10SI, 12SI, 15SI, or 27SI Delco into a 1 wire, self-exciting alternator. This regulator has a lower voltage Set Point of 13.8 Volts. Sale includes 1 voltage regulator & the rubber port plug, shown.
Note;
A 1 wire configuration IS NOT recommended for low RPM engines.
The engine must be revved up once at start up to excite the alternator. The RPM needed to turn the alternator on will depend on the overall condition of the alternator, How well the rotor and stator are matched to each other, and Pulley sizes.
Note;
This regulator can be used for 1 wire or 3 wire wiring configurations.
Once the alternator is complete and installed on the vehicle you may need to excite the alternator for the first time.
HOW TO EXCITE A 1 WIRE ALTERNATOR
to excite the One-Wire (Self Exciting) alternator you run a jumper from the post (positive power) to the #1 spade terminal on the alternator. With the motor running, you momentarily touch the jumper from the case to the #1 terminal, and then the alternator should start charging. After you have run the vehicle for a bit at above idle speed the voltage should build to the regulators set point. You can touch the jumper between both the #1& #2 terminals. Once you excited the alternator, you should be able to turn the motor off then restart and rev the motor and the alternator will start charging.
