  1. 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...
  2. 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.
  3. 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...

    Just saw this chart and figured it would be a great guide to share here. I have seen numerous posts about determining what wire size to use lately. You have to remember also to fuse the circuit according to the load.
  5. How to Identify the difference between distributor caps

    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....
  6. How To Check a Condenser on a Points Ignition

    I get asked this all the time. I have a condenser tester but I do it daily. This will work for you. This is for an analog meter but a digital works--you will see the voltage spike.Hope this helps1.) Remove the condenser from the engine (or at least disconnect the lead wire). Note the small metal connector located on the end of the condenser. This connector is the "hot" or power connection. The metal case of the condenser is the grounding point. Discharge the condenser by shorting the...

  9. Repairing a Cracked Spade on an Ignition Switch

    Hi y'all,I have a 69 ignition switch with key I bought that was used but out of a low mileage Mopar that was rotted out. That part is a different story, however the switch when I got it, I found that it had a crack in one of the spade lugs that will need to be repaired before use. Instead of getting a sinking feeling coupled with an oh damn, I formulated a plan to repair it. This repair can be used on wiper switches, headlamp switches, or any other factory switch that's tabbed and riveted...

  12. How to get Brighter Headlights

    It takes more than a powerful alternator, and more than changing to powerful replacement headlights, to get brighter headlights on these older cars and trucks. The above photo was taken with High Beams ON, and the engine was running at highway cruise RPM. 14.1 volts measured at the Horn Relay was perfect. (It’s the main power distribution buss-bar in this electrical system.) But the headlights were only running at 11.5 volts!The voltage drop to...
