Reply To: Bendix Coils Test Good, But Won’t Fire In Motor

As Dave Bernard says, don’t overlook condensers. And, don’t do a simple “ohmmeter check” on your condensers either! Just like spark coils need to be tested at operating voltage, so do condensers! Your ohmmeter test (and most capacitor testers) will only measure the capacitance using one or two volts. I’ve seen MANY condensers that “measured fine” on capacitor meters, that promptly shorted out when put back in a motor, and were exposed to the full operating voltages that magnetos generate (often 300 to 400 V peaks!) I’d be embarrassed to admit how many times I’ve made this mistake myself…..
