I bought a nice pace car that's been sitting and the lights won't go up or down. In tinkering with the vacuum lines not having a clue just seeing if there was vacuum I pulled 1 of the 2 lines in the center off and held a finger over it to see if there was vacuum and a headlight came up, did the same on the other and nothing happened. Please help a tard out!

 

The side that did not come up probably has a bad seal in the actuator.

 

That is what I was going to say. You can try an actuator rebuild kit and see if that helps. If it is internal in the actuator though you will need to replace it.

 

Or a bad relay. Do a search for vacuum system troubleshooting. Narrow down the specific problem. No sense buying replacement parts you may not need.

 

I was thinking relay, but I was think the headlights shared one relay.

Edit: I just looked it up and it appears the 68-69 have one relay for headlights and the 70 and later have two. So depending on the year it could be a relay.

To OP: Wilcox has a nice set of diagrams and instructions at the following links.

Not a guru , try pinching the green striped hose going to the actuator on the side that did not pop up. If the opposite light pops up like it did before chances are replacing the seal in the actuator will help.
You could have more leaks but this test should narrow it down some.
If pinching the green doesn't make the other light pop , your probably going to have to test the relay.

 

The Flux capacitor is the device that traditionally fails in a spacecraft or time machine and in all c-3 corvettes. The purpose is still somewhat unknown; however it seems to follow Murphy's law in that, at the most awkward moment, flux failure renders escape impossible. It seems that they only actually work when there is no imminent risk of harm or embarrassment. This forces the intrepid space or time traveller to face his fears, embarrassments , or undergo a character arc in some other fashion.

Flux capacitors are also responsible for every space related accident, from the Apollo XIII to the Challenger and Columbia shuttle disasters. However, scientists have yet to create spaceships without flux capacitors, because without the flux capacitor, something else would inevitably fail. The issue in each "accident" is obviously that the victims were not morally, physically and academically strong enough to muddle through the ethical issue that arose around the time of the flux problem.

The flux capacitor requires 1.21 gigawatts to be used and is offen in conjunction with plutonium or a lightning strike(OR a Mr. Fusion, but if you can afford one of those why would you leave your house). Many have pondered the theoretical implications of two flux capacitors being used together. Some believe this would either end the world, create another Humphrey Bogart or both simultaneously.

At least with flux capacitors you know that there is the problem. The down side is that knowing what the problem is does not solve the moral dilemma faced.

Although the military application of flux capacitors has long been known, their high rate of failure is considered problematic. This was notably demonstrated in 1943 during the US Navy's Philadelphia Experiment. Following a series of test failures in which the frigate USS Eldridge failed to go anywhere, the flux capacitor was removed from the degaussing equipment, culminating in the spectacular teleportation of the ship to the bottom of the ocean in the area now known as the Bermuda Triangle. The ship's equipment continues to function to this day, creating a constant hazard to navigation and frustrating all efforts at recovery. This is the largest Epic Fail of all time (next to taking a swig out of the "butt" can).

What is a flux capacitor?
A flux capacitor is a modern technological generator and it fails to work within reason. Many people are so frustrated with it that scientists are willing to create one that will be continuous. What was the point in making one? The purpose being, you wouldn't be able to time travel without it, for safety reasons. Time travel would practically be impossible without it, you couldn't travel among the cosmos.

"The collector and the timed switching device are incorporated in the nature of the bee-bees in brine. In conjunction with a magnetic field and the load, the flux capacitor uses the hierarchical structure of the cosmos as a timer! The trilamination of the tiny spheres with selected metals and their subjection to a magnetic field and current (sustained by the load) destabilizes the orderliness of the proton, the heavier atom and the "tissue" of individual layers of metal. The matter then seeks to re-establish itself in the fractal set."
As usual, it doesn't help at all. If you can get a working flux capacitor on Ebay, it is probably a fake. Another popular theory is that the flux capacitor doesn't do anything, it only creates the illusion of having a function. This, therefore, creates the moral dilemma of a malfunctioning flux capacitor; Is the capacitor really broken, or is it merely our inner minds, our subconscious, trying to express something meaningful about ourselves?

This theory is usually rejected in favor of the belief that the flux capacitor stores pure kinetic energy, thus the required speed of 88 mph (142 kph) in some early model time machines, and dumps it all at the point of climax, thus pushing the vehicle past the speed of light and facilitating time travel. This is purely theoretical, as it is impossible to test due to the imminent failure of the flux capacitor at the time of any experimentation.

For those who are sick and tired of the flux capacitor constant failure to work, don't worry, scientists are already at work developing a continuum trans-functioner, which is due to be finished within a couple of years; the irony of the situation is that if the flux capacitor would do its job in the first place we wouldn't have to wait.

Flux Capacitor Electrical Theory.
If anyone is familiar with the principles of leading and lagging current verses voltage in an inductive or capacitive load this is where the principle derives. My teachings at college was the word C-IVI-L. ie in a capacitive load "C", the current "I" leads the voltage "V" and vice verse.

In industry, a high inductive load for high power machinery like lathes etc, a phase shift capacitor bank is used to bring the current and voltage back into phase. Therefore if kept out of phase and a field is set up you have your time machine theory. The flux is a term used for an inductive load, capacitor speaks for itself. Shifting the inductance(flux)and capacitance you shift the phase in either direction. Forward or back in time!!!

 

Call Dr. R, spend less then $5.00 on a trouble shooting guide. Purchase a handheld vacuum pump and follow the instruction. You will find out what is bad and can be repaire and what has to be replace. Well worth the small investment. Good Luck.

Thanks Bill

 

Not a guru, I've done all this and in the end concluded that my reservior tank must be leaking around the entry point where the hose connects. I haven't figured out to fix it without tearing the front end apart...but that's where my troubleshooting ended.

 

Wilcox has great info on this problem but you do need vacum pump to work on this stuff just makes life easier Doc Rebuild has great info also and great color chart if your going to work on this car might I suggest a chassis manual and assembly manual great time savers
