Jeff,

If you are using the gear driven distributor style CAS with a controller= set up for that, you should not need to add the resistors. I am usin= g two Renesis CAS with a 12 and a single trigger tooth wheel on the eccentr= ic shaft of a Renesis engine with an EC2 set up for the gear driven CAS. To use this combination, a 1K re= sistor has been added at the CAS end of the harness between the two connect= ions to each CAS. My reference to adding a resistor from the CAS to g= round may be incorrect. The resistors are added between each CAS output and the CAS return. I have not ve= rified whether CAS return is in fact ground. In effect, a resistor is= connected from pin 4 to pin 22 and another resistor is connected from pin = 23 to pin 22. The green wire of my gear driven CAS is not ground .

Steve:

Looking at my CAS-to-EC2 wiring diagram, there are R= ed, White and Green wires connecting to the EC2 at pins 4, 23 and 22 respec= tively.

Assuming the Green is Ground, are you connecting a 1= k resistor across the Red and White wires? =96 Or are you =93Terminating=94= both the Red and White with 1k to Ground?

Are you doing this inside the CAS, inside the EC2, o= r adding it to the wire harness?

Please clarify =85 thanks

Jeff
