I had an spx30, (I just replaced it with their new Evolution model after a lightning
strike.) My X30 started to make a little clunk when power was applied to it, I never found out what it was because it did not do it all the time, and I am mostly by myself and the CB panel is a ways away, but my guess would be on power up it momentarily applies power to the drive motor
. That is just a guess. I never had any problems with it, but always was intrigued by the little thump.
As far as connections etc, pull the cover off and see if the power led for the clutch
is on. (one led for 12 another for 24)There is also another led that is an indicator for the switch for power to the Seatalkng bus, in your case you are not using it but you can switch it to "on" to see if the led lights
. While you are there, check the wires. The power leads and the leads to the solenoid/drive are the same size (large) and are screwed to the terminal panel. But the other wires (small) are screwed to removable terminals that you can pull off push on. Just make sure they are all secure, then also check the back of your control head
. I sounds like a simple intermittent connection problem. One note, the X30 uses auto fuses
, they can look good but always best to meter them.
