Brain fart regulator question Options

[mb911]

So was noticing I have less voltage while the car is running. I am use to seeing 13/14 volts as the pretty much normal. I have a fairly new marchel alternator and this year I am seeing 13v on the high side. Now I do have more electrical items, wide band o2, mega squirt, and active exhaust. Regulator going bad? Pictured in upper left. Hmm maybe I have them on the wrong pins? Might have messed that up?

I’m going to post one more which is Spoke’s simplified schematic for an alternator and 3 pin regulator

I did a strike through on a line that has no bearing to your issue.

As previously noted the voltage on the field (DF) will vary based on battery state of charge and the electrical load the system is seeing. A higher voltage on DF indicates the system is “pushing” the alternator harder and trying to increase alternator output.



Note: color codes on this reflect the /4 914 regulator wiring. The other illustration is from a 911 factory manual and 911 wiring, thus the difference in color of wires.

Note 2: the voltage measurement of DF is referenced with the regulator plugged in and functioning by rapidly energizing and de-energizing the solenoid coil within the regulator.

Thanks that will help me track it down
