  3. How points ignition works.

    Found this on the web and it is a simpe explination on how a points ignition system works.The Primary Circuit With the contact breaker points closed, a 12v current flowing from the car's battery induces an electro-magnetic charge in the primary coil (1). At the same time, a small capacitor, or 'condenser', placed in parallel to the circuit is also charged for an auxiliary purpose. As the engine-driven distributor drive shaft rotates, a corner lobe of its cam pushes the contact breaker...
  4. Adjustable Vacuum Advance

    Hope this helps out explain the adjustable vac advance. It does not adjust the amount of advance it adjust the rate of advance.This should help you can see when the screw is all the way out CCW, it compresses the spring in the vac advance, usually takes over 20 INHG to move the diaphragm when it is out all the way CW they usually start moving at around 5 INHG, hope it helps explain it.

  7. How to keep Park lights on with Headlights in pre-'68 A - bodies.

    Until 1968, the parking lights on US cars normally went off when the headlights were turned on. The early Plymouth Barracuda put a jumper between the tail light terminal and the parking light terminal on the plug that attaches to the headlight switch, to make the parking lights stay on when the headlights were turned on. For your Valiant, Dart, or Barracuda, you can remove the headlight switch and solder a jumper wire between the "P" and "R" terminals on your headlight switch to keep the...
  8. How to hook up most test equipment

    Found this chart of how to hook up test meter. It seems most people are scared of them easy peasy hope it helps. Has most of the common hookups rpm, dwell, amps, volts and ohms. This is from Sun Corporation in the 70's. Great for use on points cars and electronic also. The tach hook up is also the same as dwell if it does not have a inductive pick up.
  9. Easy electronic distributor check.

    See that a lot of people are confused on electronic distributors, pretty easy check to see if the distributor is working properly. Pull the distributor out leave the pickup wires hooked up and spin the shaft, the coil should fire. Pretty easy check of the whole system. If not firing pull the two prong plug, take the cap off and put the distributor somewhere you can spin the shaft and have a multi meter hooked up to the pickup coil plug. Set the meter on the lowest AC scale and you should...

    I get asked all the time how come my distributor cap will not fit. There are two types one for the common aluminum case distributor that fit both point and electronic units then there is the dualpoint cap that fits only the cast iron distributor housings. The aluminum has a internal slot that the tab on the vacuum advance fits into and the dual point (prestolight) distributor has a tab on the cap that fits into a slot on the hold down clip. Here are some pictures of the difference....
