Hi everybody, here's a weird one that has me stumped.  I recently switched clocks in my 63 for cosmetic reasons (neither works which is okay new one looks better).  The old one had both light and power wire hooked up, so I figured I'd do the same with the new one just because I like to cross my t's & dot my i's.  Here's where it gets weird:

When I hooked up power lead to new clock, the light came on even though it wasn't touching ground and headlight/parking light switch was off.  While the clock was still in my hand, I turned the parking lights on and the clock light went off.  When I tried to install it, it sparked out as soon as it touched the dash bezel.  I disconnected it and reconnected the old clock, it worked normally, light coming on only when parking/headlight switch was on and no shorting when it touched the dash.

After a few tries with nothing changing I decided to install the clock without the power lead connected.  As long as it's not connected, the light works normally - off when off and on when headlight switch is on.  But for the life of me I can't figure out what the deal is.  Doesn't matter since the clock is non functioning, just there because it looks better than old one...but I'm still curious.  

Anyone ever have this happen?  Thanks!

@Mark - That makes sense, I'll bet that's what's happening.  I did check the rubber insulation around the positive power feed and it was perfect, so no short there...looking back wish I had paid more attention during those high school electrical shop classes!

I think my comprehension level is in the dumps these days. I read new clock as literally a new clock or at least an original converted to quartz! Kurt and Mark are spot on with the idea that the contact may be staying closed if you have a "new" original clock with the original electro-mechanical mechanism. My bad.

RPM at 70

I was questioning if my 63 was shifting into 4th , so I installed a tach and don't notice a 3-4 shift. Cruising at 70 the RPM is at 2600. Sounds high.  Has anyone noted RPM's at highway speeds?. I…Continue

Torque converter grab when idling in Drive

Posted by Cliff Johnston on June 14, 2021 at 8:47pm 2 Comments

Hi Everyone, been quite a while since i have been on here.

I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.

With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.

I've had the car dyno tuned and…


Can you help? Driveshaft Question....

Posted by Chris on May 30, 2021 at 8:55am 1 Comment


Newbie to the group here - we have already found tons of invaluable information on the board, so thanks! We are restoring a 1963 Series 62 Convertible. We are wondering if anyone knows of a source to buy the propellor yoke flange (that bolts to the pinion flange) for the driveshaft? One of our ears partially broke off. Not sure if we can buy just the yoke flange as an aftermarket part, or if it has to be rebuilt by a welder/fab guy? Maybe a salvage yard for a source? Again, any…


Thank you Kurt re: VIN location

I just wanted to say a thank you to Kurt for steering me to the tech tips page on V.I.N. locations.  Excellent information.  Thanks a bundle.

V.I.N. where?

Posted by Robert Pellow on April 18, 2021 at 1:41pm 6 Comments

Where can I find the V.I.N. on a 63 convertible?  The usual space at the base of the interior windshield on the driver's side has been decimated by weather.
