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? – Or are you “Termin= ating” 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 … thanks

Jeff

Ed,

I tested the engine on the = stand with variable resistors across each CAS yesterday. With the engine id= ling at about 1500 RPM, less than 100 ohms resistance across either CAS would cause the engine to quit completely. Resistances this low= must decrease the voltage generated by the CAS to a value too low for the = controller to use. The engine would not start with 200 ohm across one CAS a= nd 1K ohm across the other. It didn't matter which CAS had the lower resistance. The engine would start with 300= ohm across one CAS and 1K ohm across the other. This makes sense since the= CAS cannot generate a very strong signal at cranking speed.

What doesn't make sense to = me:

Starting with 1K resistance= across each CAS, if the resistance on one CAS was increased to 69K, the en= gine would still run fine at 1500 RPM. If the resistance was increased to 69K on the other CAS, the engine would only run on one rotor.= It didn't matter which CAS resistance was increased first.

With 1K resistance across o= ne CAS, changing the resistance of the other CAS from 69K back to 1K by con= necting a wire would sometimes cause the engine would miss what seemed to be one firing event. Again, there was no difference in the = behavior of either CAS in this regard.

The conclusion seems to be = that adding the 1K resistor to each CAS seems to be beneficial and the valu= e of 1K is not critical or on the threshold of causing other problems.
