i need help soon.. electrical problem

I realize that your electrical skills may not be that great, but you need to determine IF you can, that you need a regulator BEFORE you buy one and put it on the car

I suggest you re--read this thread, carefully, and try and give us a detailed post about where you "get lost." Or let's start fresh right from here. What have you checked so far, and what have you determined?

There are some basic "firsts" WE NEED TO BE SURE OF in concrete

Question1:

Does your alternator have one or two "push on" field connections?

IF it has two "push on" field connections, is one of them jumpered to ground, or do both field wires lead off into the harness?

Question2

BE SURE what you have for a regulator. You seem to think it is a 70 / later as per the photo? Does it have a triangular connector like in the photo?

60-69 regulator, for alternators with ONE ungrounded (push-on) field connection:



Replacement aftermarket solid state regulator fits same as above:



The regulator below fits 70 and later. The alternator MUST have two "push on" field terminals:

Ignore the color and part no. It is probably black. NOTE the shape of the connector
