I get alot of questions on points and electrical aluminum housing ignition rotors the early ones 1961 to late 78 use the CH-308ones. The later use thech-303 which are some times sold as fitting (ch 308) but are taller and hard to put on the shaft and will wreck the cap. CH 308 CH 303

OK where do I start. There is a ton of mis leading information about adjustable Vacuum advances out there. None of the mopar NOS or aftermarket are adjutable for the amount of advance, just the rate of advanc. Yes you can limit them with wire etc, but they are just adjustable by the rate of...

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...

There are a ton of fake ecu's out there two easy wats to tell at a glance are the height of the transistor, usally the fake ones are around 3/8" high and a real one 5/16 or so. Another way to tell at a glance is if there is printing on the transistor and also a insulating pad under it. Just...

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...

Forgot I had this older chart on ignitions. Basically walks you through any issues you will have. I have always thought this was very helpful when I was just starting to get into cars around sixteen years old. Hopefully this will help out members walk through ignition issues.

I get asked quite a lot if I have points. A lot of descriptions say just 340, 360, 400, 440 etc. and misleading for sure. Here is a picture so you know what to look for. E bay is notorious for it. Now you know the difference in a picture. Very easy to confuse since they are mirror image of...

Easy tool to make from a churchkey, heat shrink and a popsical stick. Bend the can opener and grind the tip off of the can side. Open the tab on the bottle side a bit. Then put a bit of heat shrink or tape over the tab. I use hot glue to put the section of the popsicle stick on. (you will...

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...

Great article. Not mine. The centrifugal advance system in a distributor advances spark timing purely as a function of engine rpm (irrespective of engine load or operating conditions), with the amount of advance and the rate at which it comes in determined by the weights and springs on top...

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...

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.

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 helps 1.) Remove the condenser from the engine (or at least disconnect the lead wire). Note the small...
