Alternator not charging

[miniwally]

I have a CS 130 on my buggy with one wire going to the plug and that's it. I don't run a voltage gauge so I don't know how that would play into the vehicle side wiring.

All you need is a 12v switched reference for the alt. to get excited. This is the one wire going into the plug on mine. Then the charge wire from the lug on the alt. to the battery.

Nothing special. I am not in front of the buggy and won't be for several days but you only need one wire for it to work.

Gauge shouldn't have any effect, most of the time the gauge isn't reading right off the alternator.

Not sure how you are running it, without a resistor they are NOT supposed to work?? Dunno, never tried without, thats just what the manual and all the articles I read on it say.

Just an update:

There is a light, but its in the blank gauge spot and its real faint, but it is there and it does work. I took both alts down to Advanced Auto and had both tested. The new one didnt do anything, so its back to AZ for a trade. The one that originally came outta my truck that I thought was a working one, wasnt. Put it on the tester and it was showing voltage, but only half what it was supposed to be. So I got a new one from Advanced, put it in, and its been working ever since.

Dorian: I know the question hasd been asked, but I cant find the answer. What is the resistance range for the brown wire. I think when I put the dual alt setup inthe other Burb, I might have damaged the second alt by running the brown wire straight off the gauge. When I pulled it, it was still reading 13.5 volts from the lug on the alt, but that is down from 14.1 when I first put it in.

Buried in here I believe.

Sweet! It looks like anything from 35 ohm-500 ohm resistor would work, so I'll get something in between and see how it works. I do remember reading that thread before, but couldnt rememebr how I found it.

Looked at my plug this weekend.

I am using the brown wire in the 87 sub wiring harness that is connected into the L terminal on the ALT.

The ALT. is labeled PLFS. No issues with this setup for 5 years on the same alt., although this is on my buggy so that 5 years equals 1,500 miles? But it does have many hours of run time on it.
