Re: red n white wires

i am looking at a stock 1970 wiring diagram, the red wires goes from Alt. to a Junction where it meets with the orange (#3 slot) wire from the voltage regulator and from there to the ignition switch. The red wire is the power wire, i usually run that directly to the J block next to battery -with a fusible link.
The white wire goes from Alt. to the #2 slot on the voltage regulator. This is for a stock set up.

voltage regulator slots

#4 #3 #2 "F"

Re: red n white wires

Are you talking about a red and a white wire or a red with white stripe wire? Are they part of the charging system? Are you using the stock external regulator?

Hey Hector T

Chill out with the multiple posts man

We need more info.

Take a look at the back side of your alternator. Look at the small plug socket.

If the terminals look like this: l l
It's a factory style alternator that requires and external voltage regulator (external voltage regulators were mounted by the driver's side headlight buckets).

If the terminals look like this: __ __

It's an internally regulated alternator that someone has installed. These DO NOT use the factory voltage regulator at all.

Please let us know what you have for starters...

Re: Hey Hector T

Hector,

Your aftermarket plug-in connector typically has the red on the right side and white on the left side (this is as you are looking at the rear of the alternator).

Although just connecting the red to the battery lug on the rear of the alternator isn't the ideal spot, it will get you going for now. The white wire needs to ultimately connect to the brown wire at the old voltage regulator plug.

Wes show's a blue wire being used, but as long as you get the correct terminal plug wired to the correct points, it should work (unless there are other issues like a faulty alternator)...

Is this the plug you're talking about?

Re: Hey Hector T

Thanks...I do have that same plug...my red wire is going to the battery terminal On rear of alternator...then another red one (we added it) straight to battery positive side...my white wire is still dangling...unconnected. Yes my car fires up and I can drive it...but once on road...it shuts off...and then won't start as my battery is drained (new battery by the way)

Re: red n white wires

White wire needs to go to one side of the "ALT"/"GEN" light with the opposite side connection at the light going to switched 12v power.
