Guys got a 70 454 and sometimes the clock runs backwards and when it does the volt hand shows discharge but i checked the voltage with a meter and it is charging even though it say negetive charge.
What would you guys say makes my clock run backwards and the gauge discharge,,dont do it all the time just sometimes.Im thinking a ground somewere!

Could be you have been to the graveyard one time too many.
The clock is mechanical. When the clock ticks down the points close for a split second and springs take over until it ticks down again.

Check the battery voltage with the engine off and on and check the voltage at the alternator at idle and at 2000 RPM and post the results.

Does it only happen when you go 88 MPH....?

If that's the case, you would have to check the flux capacitor. And you would need your alternator to produce to 1.21 Gigawatts!

I replaced mine with a crystal one from stock. It would run backward after the battery was connected sometimes. What fixed it was disconnecting the battery and reconnecting repeatedly, takes a few times until one time it comes on going the right way. Then stays right until battery is disconnected again.

No way for the ammeter to operate in reverse...SOMETIMES...

I don't know if this will help at all, but when I reconnect the battery on my 70 454, the clock will run backward for a second or two before going clockwise.

It seems to me that somehow -12V is going to the clock instead of +12V

You'll never be late!
Mine stopped at 7:37 so its right twice a day.
Sounds kinda crazy running backwards but hey these cars have
a mind of their own sometimes.

Thats one way to go back in time....

That is an awesome clock. I wouldn't fix it......
Every time I sit in our stingray I go back in time to the 70's.
(the 70's sucked however). But it's my way back machine.
Now if I can just connect with mr. peabody and sherman.........

Great love it

It is typical for the reproduction quartz clocks and quartz conversion kits to run backwards for a few seconds when they are started up.

Cue the movie song, "Back in Time"...

Ernie: Ever see an ammeter read 'backwards'....occasionally??

Charlie-

Only when the flux capacitor is clogged... and the brillium crystals are hot.... lol..

I will say the if the ammeter is discharging, the clock issue is not related to that problem. If the clock is quartz its possible he has a short or a loose connection and that might explain why the clock keeps running backwards... It's easy to tell if he has a quarts by watching the second hand... quarts sweeps... and original borg movements sweep.

Thanks guys,love all the attention from the clock but i have not had a chance to check the voltage but it will,and i do have a batterey diss connector ever time i shut the engine off and put it up for the day i turn the **** on the NEG side and it turns the power off,safety switch on ground terminal.

Place a multi meter in line as show below... then start pulling fuses until the amp draw is gone. Once you do this you'll figure out which circuit the issue is on. When you do, post back and I'm sure people will help you find the issue. (note: you can use a test light in the same manner and when the light goes out you'll know you've found the circuit unless there is more than one).

My tech page has a free wiring tracer diagram for you too.. copy this picture and paste it into your paint program. Once saved you can then trace a circuit with ease.

Thanks for the info,but i dont have a amp draw i just like to disconnect the power after ever ride for peace of mind.The clock only runs backwards sometimes when i am driving the car.

0Willcox Corvette

well that explains why the clock is running backwards when you start it up.

ok
