ELECTRICAL Trigger Coil Testing PVL Ignition Troubleshooting (700, 900, 1050 Engines) IrCJuTi9N J Verify spark plugs are
fall rapidly once the spark plug is firedThese alternating currents are suppressed by the use of resistor spark plugs and
resistor spark plug capsAlthough all resistor spark plug caps that Polaris uses have 5000 ohms of resistancethey arrive at
this resistance value differentlyThe construction of the resistor within the PVL spark plug cap enables it to dampen spikes
of ignition current and therefore better control RFI (Radio Frequency Interference) than other resistor spark plug capsThe
creation of RFI can distrupt the the micro-processors within the COl box and cause ignition misfiringFor these reasons it
