Hey, I'm trying to trouble shoot an issue with my 1995 240sx se ka24de. The car is a manual.

The car is not charging.

Here's what I've done so far.
Checked all fuses and fusible links with a multimeter.
Swapped out a couple different alternators, had one rebuilt.

The only issue I see is the battery light on the cluster never comes on. It doesn't come on when I start the car.
I checked the bulb and it is good. It used a multimeter and it's getting voltage.

There is no voltage at the main terminal on the alternator.
There is voltage at the two wires that run into the plug.

All voltage is very close to the battery voltage. No major drops.

Any help would be appericated
Thanks in advance

You have a break in the wire between the alternator and the gauge cluster. That's a signal wire that tells the alternator to start charging.

I've got 12 volts at both the yellow and red wire at the plug on at the back of the cluster.

Is there anyway to bypass it?
