regulator capaitator

[Wayne P.]

I noticed at a car show another corvette had a capacitor plugged into the regulator. This might be why I have a lot of static on my radio.
Is their a difference in the type of capacitate for a 1964 . I saw it on a 67. Does anyone carry it in Ontario ? Thanks

Re: regulator capaitator

Here is how its mounted.

Thanks Alan . My regualtor is on the driver side fender.

Alan -

I see in your photo the capacitor is attached using the top VR mounting screw (the correct configuration for a 512 VR in '63), but I believe the capacitor should attach to the tapped hole on the base plate of the 515 VR used in '64. Am I missing something?

Re: regulator capaitator

Hank the 63AIM, Sec U69 sheet 7.00, shows cap #2 mounted to top screw of VR
64AIM, Sec U69 sheet 7.00, shows cap #2 mounted to top screw of VR
Then in the 64 Shop Manual Supplement section 13-3 again shows same top screw as the mounting location
That entire area is comprised of original parts (cap, VR, HR) as an added bonus.

Not sure what "the tapped hole on the base plate" location is???

Re: regulator capaitator

Allen,
I was just wondering that too because there is a black ground wire on my 67 that grounds the regulator base.

The size of the hole is bigger than the screw that is tapped in the base but fits the mounting screw perfect.

My cap also fits the mounting screw perfectly.

The base plate hole I referenced in post #3 is pictured in the following thread:

Also, Sheet B4.00, Section 6 of the '64 AIM shows the capacitor mounted on the base plate too. Perhaps the drawing in AIM Section U69 wasn't updated for the 515 VR?

Re: regulator capaitator

Dom a 67 is a little different in mounting which may have happened for 65 model.
Although -
the 64 AIM, Sec6 sheetB4.00, shows the VR mounted on the wheel well skirt with floating screws
and plastic nuts (not sure of nut material) A separate ground wire went back to the HR to complete the circuit.
That mounting setup is again seen in 64 AIM, Sec12 sheet A8.00. (look at the location of my VR above)
However for the most part such was not used in 1964 (never say never)

Now Wayne has his VR on the drivers side (assume due to an option AC?) so I'm not sure how its mounted. If AC the AIM shows mounting to driver's side skirt, Sec C60 sheet E3.00, at 3 dimple locations. Note my skirt does not have dimples on that skirt.

Re: regulator capaitator

Allen thanks,

Maybe someone out there has a pic of a 67 with the regulator on the drivers wheel well.

Re: regulator capaitator

Thank you Hank (I think)
My VR is the later 515 however the case hole has never been tapped - the cap was still mounted in the upper hole.
If you look closely at Sec 6 sheet B4.00 it does call for the cap and ground wire to be mounted on the base plate with screw # 1, 9419305. Believe the wheel well skirt also got changed for 65 and surmise that's when the VR got a mounting location change along with dimples added for options.

Dom -

Here's my '67 - all had the 515 regulator on the driver's inner fender.

Re: regulator capaitator

John, again you came thru with the answer.

When you get a chance can you take a pic above on the upper side of the fender well because I need to see what the harness does as I have 2 holes that look like there were clips there that held the harness that go's to the head lights, park lights & horns.

Here's one of that area.

Re: regulator capaitator

Thanks John,

That's exactly what I needed to see.

I put the complete front end on my 67 back in 1971 when things only had to function and was lucky enough to save my old broken fender wells along with a few other front end parts.

I recently drilled the holes in the left fender well and needed to see the wire routing and how they fastened in the holes.

John or other,

Here is a pic (below)of my wiring at the regulator. When I move them to hook up as yours they want to be in another place.

If I hook the capacitor up to the 6/32 screw on the side (1) it wants to smash the voltage regulator cover. (2) the capacitor mounting hole is much larger than the 6/32 screw but fits the regulator mounting bolt perfectly.

The black ground wire also has a hole size that suggests it fastenes to the regulator mount.

Is there something wrong here?

I woludn't think that a SB is different than a BB at the regulator?

Also here is a pic of my ALT that must be clocked 90 degrees off.

Any suggestions as to where my problem is?
