I got a new BWD select voltage regulator for my '63 Super. Looks entirely different. 4 connectors across the bottom. My original has three leads going to it: purple, black and red.

Anyone know how to hook this up?

MDchanic

Yup.

The problem is that you have the wrong regulator.

'63 had a one-year-only setup that had a separate voltage regulator (three terminals) and warning-light relay.
The following year they put the two components together into the four-wire regulator that was used for years after.

You can redirect the wiring to work with the newer regulator, as shown in the diagrams here (reposted below), by using the (+), Field, Light, and R wires, and capping off the green wire to the ACC circuit and the extra Red (+) wire.






Alternatively, you could return your regulator and search for the (more rare and expensive, one-year-only) regulator that your car came with.

Did yours look like this one?

That's a generator regulator - '63 should have an alternator.

Aaaah, I see. That's why it's listed for 61-62's.

I found no 63-specific listing. All the standard auto part websites shou the regular 4-terminal version (64-up).

MDchanic

Exactly. That's why his easiest solution might be to swap a couple of wires and use the newer one, unless he's looking for a 100-point restoration.

No - I will try the wiring diagram - just trying to get this thing moving. thx

Okay guys - I checked the other thread where the diagrams came from and have one problem. My light relay only has 2 leads - green and black. My voltage regulator has purple red and brown.

My voltage regulator has F 2 3 4. From the diagram looks like

2 - Purple
3 - Red
4 - Brown

Green gets capped off and Black goes to F

Right?

MDchanic

Post pictures. Green and black is your horn relay.

Here you go Eric.

You are looking at this relay, right?



- Eric

pbob42

That is what I am thinking. Three lead (should have shot a pic from the back) : Purple, red and brown. If that other relay is for the horn I am not seeing the light relay.

MDchanic

The relay circled in yellow is the alternator warning light relay.

The relay next to it, with the main power stud on it, is the horn relay.

Your voltage regulator (three-wire) should be on the firewall near the center.

The light relay and the regulator are next to each other in the schematic, but not in real life.

Golly gee whiz batman - there it is! 4 wire voltage regulator plain as day.

Now - where can I get a new warning light relay?

Thanks Eric

MDchanic

If you've already got a four-wire regulator, then someone else probably rewired it and the warning light relay isn't being used, as it is incorporated inside of the four-wire relay.

Maybe really close photographs of all of these parts and their wires are in order.

great news - thanks

MDchanic

Just be sure to look at the schematic and run through the wires to make sure that everything's hooked up right - when "the other guy" rewires the car, you never know what he could have done.

And make sure everything is soldered - no twists, crimps, or () wire nute!
