Aftermarket Alternator/ Does The stock plug need to be hooked up at all?

It appears the car is trying to compensate in some sort of way with the idle for the voltage.
i currently have an aftermarket alternator installed in my CRX 89 DX 1.5 liter... it is externallly regulated so the stock alty plug is just laying there not hooked up to anyhting...

The engine is acting funny by quickly reving up and down causing lights to dim. brighten quickly.

I heard that the stock plug has to be maniputlated in some way in order for the computer to think its controlling the voltage... or something... either way...

I checked the plug last night... there are
2 vertical pins and 2 horizontal pins below the vertical pins...

The 2 vertical pins are remote hot lines giving the battery voltage.
the bottom left horizontal pin is a ground
The botomm right horizontal pin appears to be the field line giving 4.5-4.6 volts.


Help anyone? I leave tomorrow going on a 600 mile trip with the car...



PS! The Grounds ARE ALL GOOD.... i over freaking grounded the car...

 

cliffs are.. basically...

if i have an external voltage regulator... do i need to have the stock alty plugged in at all? or ghetto wired what so ever....

 

ttt for answers!

I am glad to find your site - now I know what a good one looks like.
Very good topic to share with us. Great info.

^The above guy is spam.

Show a picture of it, I wanna see what is being talked about before I answer.

are you saying to have an EXTERNAL V-REG that you wired up?

 

yes

 

I would PERSONALLY run the OEM regulator. Not a fan of aftermarket ones that make the alternator SCREAM to its limits.
