This type of problem is capable with PWM cable that are not fully inserted. If you are using the newer Spike it is more difficult to get the cable fully inserted. Remember that the Spike input is a wire for each of two relays, it is not a PWM signal. If one of the inputs is intermittant and meant to be pulled to ground, the Spike will pull up when the connector is open. If your Spike has had the input spread open, it is possible to have an intermittant connection.
