1966 roof issues

[sauceman]

Well I got my first LCC in the shop,

1966 LCC in the shop.

The deck unlock and deck open relays are both shot, I had to bypass them both to get it open,

Getting to the relay bank.

To get the roof to operate after the trunk was fully opened with the jumper, I had to use the fender switch,

Fender switch

The dash switch does nothing. Tried it in park and neutral, engine running and just on ACC, nothing. I suspect the neutral/park relay on the drivers inner fender might be to blame lol.

Fender relay.

After I got the roof to cycle I noticed that the hydraulic check valve beside the pump was pissing oil from the bottom.

Check valve

On a positive not there was a build sheet under the rear seat

Now to order some parts!

I also need to figure out the window drop on the left side. The window went down but now won't go back up when I close the door. The window switch on this door is very stiff as well.

I can rebuild your check valves for $75 each. I have also just reproduced the "spool" for these check valves, so can replace it if the viton tip is worn out.
Feel free to call me if you have any questions about getting your top working.

I can testify from personal experience that John can help get the convertible top, deck lid, etc working by phone consultation. Thanks for all your help John.

LOL. That's the brake lamp relay.

Hmm, well could you inform me as to the actual location of the neutral/park relay, as according to the shop manual this is the only one in the described location.

The relay on the rubber block is the brake relay. The block is to reduce noise transmitted into the cabin. There is also a TSB for this.

There are other relays under a black plastic cover on the inner fender just below and in front of the master cylinder.

66 Relays (cover and brake booster removed)

Black Box covering Relays

There's a park/neutral relay for the TOP and it should be located inside the black box.

Top Control Relay

It has four wires, 194/799-Red, 798-Red-black Stripe, 305-Orange, & 293-Violet. Not sure what color the connector is.

Jumper 305 to 293 to bypass it.

PM me if you have any 66 questions. I've had mine for 18 years. I know it inside and out.

[sauceman]

Groovy, thanks!

As always, I recommend John Cashman for top issues. He's the man!

[sauceman]

Big shout out to JAB for taking my call today!

I bypassed the neutral/park relay under the hood so that got the dash switch operational.

Have traced the issue down to a bad deck open switch,

When I hit the dash toggle switch power goes into the deck open switch were it's supposed to, but doesn't come out. The issue is only happens when opening the deck lid from the stowed position. If the roof is already up it will function as designed all the way to fully stowed, but when trying to put up the roof it won't function until I bypass it to the deck raised position.


fun fun fun

You can clean and rebuild this switch on the bench. Use twisty-wire to hold it together if you don't have small screws or rivets.

There's nothing but a roller inside that slides over embedded contacts.

Cake. Maybe 30-60 minutes to rebuild. Just charge him by the hour.

Thanks for that Dan,

Got to love old cars where you can actually fix things instead of just replacing them LOL!

Dan,
I think you are referring to the deck lid down limit switch. The deck open limit switch on a 66/67 vert does not have roller contacts. It has two contact brass tabs that are moved up and down by the portion of the button the extends into the switch.
Cleaning the contacts and contact tabs requires a delicate hand to clean the surfaces without damaging the tabs. Sauceman just needs to be extra careful when dismantling and working with this switch.

I think you're right, John. Either way, it can be cleaned up.

This is a simple plunger switch. You'd think we'd be able to find a reasonable substitute that does the same, except it's hard to find something with three contacts that do the same thing (open some, close others).
