I temporarily connected that kit to a Delco (Denso) 90 amp oe replacement alternator, (98 XJ) adjusted to the lowest voltage setting, voltage output is around ~17 volts, measured directly from the alternator's output.
With the PCM (EVR) connected alternator output is normal ~14 volts. I'm wondering if the voltage reg. CP3818 that came with the kit is faulty or some sort of incompatibility?
Everything was wired as in the instructions, along with a ground wire, except the battery was used instead of the ign. as 12 volt power for the CP3818.
I have another large case Denso alternator that's suppose to have been upgraded to 200 amps. Though I don't know which parts of the alternator were actually upgraded. A good High Output alternator will use six phases vs an OE three phase, plus upgrade the stator, rotor, rectifier and diodes. To have better output at lower rpms. A good high output 200+ amp, should be putting out at least ~100 amps around idle rpms and designed for better cooling.
Im not sure why yours was putting out that kinda voltage. Mine only puts out 12.5 to 14volts. I have it run off the power wire from fuse box.
