Okay, an update.

I pulled the connector on the frequency valve. It does get 12 volts. Without the plug connected, the engine seems to want to stall and runs rough.

I'm going to check the other components. If the idle control valve isn't getting juice then is it safe to say that the idle control unit isn't either?

If either is the case and the overload protection relay is functional (i've tested it), could there be a ground fault somewhere? Or is there a box of fusible links I'm not even aware of?

Thanks,

-Troy
