More ignition issues on the dart

0.2 what? Ohms? Volts? The continuity test is NOT conclusive. The voltage test IS.
Continuity is looking for...continuity. Very low resistance. At some point, if there is too much resistance in the device being measured, you will not get a beep. This can also vary between meters. Also, the resistance of the p/ups can vary 150-400 ohms. 150 ohm unit might beep, 400 ohm unit may not, but both are actually ok to use.
Use the millivolt test. It is more accurate & tells you all you need to know.
