Test Gen 4 Ignition Coils Is There A Way

[Rocket]

Thanks in advance for your help. Is there a way to test each individual coil on a Gen 4?

Use an Ohm meter , check coil resistance with factory specs and check the coil to ground, should be infinite unless you use a Meggar .
I've seen situations where the problem only showed in the hot condition....

Good Luck !

Here are some specifics from the 2009 Viper Service Manual on CD



IGNITION RESISTANCE


IGNITION CABLE RESISTANCE

MINIMUM....250 Ohms Per Inch (3000 Ohms Per Foot)

MAXIMUM....750 Ohms Per Inch (9,000 Ohms Per Foot )



IGNITION COIL RESISTANCE

Primary Resistance at 21°C-27°C (70°F-80°F)....0.530 to 0.650 ohms

Secondary Resistance at 21°C-27°C (70°F-80°F)....10.9K to 14.7K ohms

Thank you! Will definitely check it out under cold and hot temps !
