Electric steps help?

Thanks for getting the pics. The solenoid he is stating is clicking is the Intellitec Battery disconnect relay. I have a hard time believing that relay can "Click" from a load. NEVER in 40 years have I had a Intellitec relay "Click", other that doing its job. Since the 12 volt Circuit breakers are within a few inches of the Intellitec, I think it is that breaker for the Red wire. So, he needs to attach a voltmeter to the Red wire side of that Circuit breaker and watch and listen to see if that breaker opens and closes and he loses 12 volt power. That Intellitec disconnect is a latching relay. Doug
