Re: Alternator choice ? VR715 voltage regulator?

This is regarding swapping the taller original voltage regulator cover for short plastic cover that came in the VR715.

I pried the plastic cover off the VR715 today and went to put the taller original cover on.

What I found was that the original metal cover will not fall down all the way in place over the VR715. The frame of the VR715 is slightly larger than the original regulator. About a 1/16 inch in length and width.

I can center it and screw it down but it sits a little high. It's not a big deal and probably no one will notice but I was just wondering if anyone else who did the swap found the same thing.

Darn, not a perfect fit like mine was. Mine had the Delco Remy logo on it. Sizing may have changed on the VR715.

Re: Alternator choice ? VR715 voltage regulator?

When I refer to my original, it is not the original from the factory. It is an Echlin brand parts store replacement but it had been on the car since the early or mid 80's so it's pretty old. I don't know if that could be the culprit or not.

Re: Alternator choice ? VR715 voltage regulator?

I found better valve cover clearance on my 67 with the 12 O'clock terminal position. I think an electronic Voltage Regulator is a good idea if you will have any modern electronics in your Camaro.

The old mechanical voltage regulators introduce a lot of "noise" into the electrical system. Just look at your headlights flicker at idle & you'll see what I mean. Those voltage fluctuations can't be good for modern stereo systems or even electronic ignitions.

Re: Alternator choice ? VR715 voltage regulator?

Yes you will find while most of the other old mechanical Voltage Regulators looked like the DELCO ones that replace subtle differences in size and shape occurred.
On the ones I replaced the black plastic cap with it was a true original DELCO VR high hat cover. Now a days I don't car so much and just use the VR as is out of the box.

Re: Alternator choice ? VR715 voltage regulator?

Thanks for the replies......

If I reuse the rubber gasket from the original regulator and put a little sealant around it, once I tighten down the two screws holding the cover down, it will be fine.

After hearing of so many people swapping covers, I was just a little surprised when it didn't fall right into place.

Take a look on-line as well. A few people used to sell reproduction high hat covers with pretty good A/C Delco embossing.
Here is one currently on eBay

Re: Alternator choice ? VR715 voltage regulator?

For now I am using the cover from my old regulator. It's plain with no embossed lettering. I repainted it and it came out OK. The money for a Delco Remy NOS is better spent elsewhere on the car right now. I keep my eyes out at swap meets though, for a Delco Remy embossed cover.

I did reuse the old gasket. It was a better fit to have the gasket between the old cover and the new regulator rather than trying to put the old cover directly on the new regulator. The gasket was pretty hard so I put a thin bead of strip caulk on both sides of it. It worked out well.
