ELECTRICAL Trigger Coil Testing PVL Ignition Troubleshooting (700 and 1050 Engines) Verify spark plugs are RESISTOR TYPE!
spark plug is fired These 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 resistance, they 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 is extremely important
