Description: This Heavy duty kit is what you need to rebuild your stock, or aftermarket, Delco 12SI alternator or convert it into a self-excited, or 1 wire alternator. This kit includes all the new parts as shown in the picture. A heavy duty 140 amp Rectifier, diode trio, complete brush holder assembly, drive end 6203-2RS bearing, slip-ring end needle bearing, 12 volt self-exciting voltage regulator, regulator port block off plug, bat. Stud kit, capacitor, & 6 new screws. Fits all 12SI OEM Automotive alternators & aftermarket 12SI units as well. With 6 70 amp diodes, the rectifier in this kit is easily heavy-duty enough to handle the Power master 140 AMP units. I have many other kits listed. If this kit does not meet your needs, check out my Ebay store and feel free to ask questions. If you would like more than 1, try use the Priority shipping option. It will save you on shipping. 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. If you have any questions, feel free to ask. All items are in stock & ready to ship. Items ship out the same or the following business day. All customers will receive a USPS tracking number.
