Though reliable, points-based ignition systems can be tough in that precise timing is critical for a good running engine. Worse, point gap is tough to maintain as the points themselves constantly wear thus changing the gap. Electronic ignitions solve these issues in that, as the spark provided by an electronic ignition last far longer than with points systems, timing is normally simple. Additionally, as “hall effect” magnets are used to trigger spark there is no point gap to maintain.
Any HD / Columbia cart can be converted from points to an electronic ignition by way of using an HEI (High Energy Ignition) module that was used in many 80s and 90s era cars. This same system can be used to replace failed Columbia ignition modules on later carts but you will have to acquire points, a points plate, and maybe a points cam to do so (depending on the factory cam end). Note that the points used in HEI conversions do not act as traditional points. They serve the same purpose as the “hall effect” magnets in electronic systems that trigger the longer spark. As such, point gap in an HEI system is not critical and, for the most part, they will wear much more slowly if at all.
Converting from points to the HEI is inexpensive and can be done for as cheap as $20 and up to $100 depending on the type of HEI module you choose. There are many different types of HEI modules available (normal use, racing capable, etc.) from many different manufactures. For the most part, if doing this conversion there are two components that you will need to add to your cart; the HEI module itself and some small circuitry that has to be soldered together. Attached are two documents that detail the HEI conversion; one speaks to the conversion in a general sense to include needed materials, the other is that applies this information to HD / Columbia carts.
