There are kits available which turn your old points distributor into an electronic ignition system, i have converted both my veedubs and it removes all of the guesswork & trouble from your distributor. The kit comes with instructions and is very easy to use, you basically just gut your distributor cap & put in a circuit board & boom, electronic ignition.
I will post a link below. Oh, and gap your plugs at .024 inches.
Points .017 and spark plug .035
The dwell for the points should be 30 degrees. The spark plug gap should be .040".
Dwell angle is simply the amount of time the points or electronic ignition components are in a closed state to charge the primary side of the ignition coil for firing of the spark plug.. This time is expressed in distibutor rotation, hence the degrees..
1978 to 1981 DT-175 with CDI (no ignition points) spark plug gap .6-.8mm or .024-.032 inch, spark plug# B9ES
1978 to 1981 DT-175 with CDI (no ignition points) spark plug gap .6-.8mm or .024-.032 inch, spark plug# B9ES
.035 for points type ignition and .045-.050 for duraspark ignition
Okay it break down like this; 1, the ignition. coil. 2, trigger or ignition module, 3 spark plug wire, 4 spark plug. You dident ask how it works. Wanna Know? I'm kolher. The primary system is the the low voltage side, points, ignition module, primary side of ignition coil and ignition switch. The secondary windings of the coil, coil wire, distributor cap, rotor, spark plug wires and spark plugs are parts of the secondary system.
The ignition coil is the transformer that puts out the voltage required to make a spark jump the points of a spark plug. this in turn lights the petrol which pushed down the piston.
Gap the spark plugs to .035. Set the points to .018.
With a points ignition the gap should be .035
the gap on the distributor points is .016, the timing is advanced 4 degrees and the spark plug gap is .030
No. On "conventional" ignition systems, i.e., those with typically a single ignition coil and a distributor with distributor cap, the spark plug boot is that portion of the individual ignition wire, running to each spark plug, that terminated the ignition wire at the spark plug and provides the wire's electrical connection to the spark plug. In newer, "plug on coil" systems that do not utilize a distributor and wires, and that are characterized by having an individual ignition coil mounted atop each spark plug, the boot is that portion of the ignition coil that pushes down over and on to the spark plug. Some few designs use a replaceable boot. Most incorporate the boot into the coil assembly.
