Correct Solenoid Valve for Demco DA10 Actuator

Question:

When using item# TK71-755-00 does this need a ground wire ? This was what I had previously on my old DA10 surge hitch which was a metal housing. I since then had replaced the actuator with the now plastic housing and solenoid but having grounding problems.

The Solenoid Valve Replacement Kit for Titan/UFP Brake Actuators with Reverse Lockouts # TK71-755-00 only has a single wire, not for ground, and the issue may be that you do not have the correct replacement solenoid valve.

I say that because you mentioned having a DA10, which is a Demco actuator, and for which the correct replacement is the Replacement Bypass Solenoid Valve for Demco Brake Actuators # DM05561.

This does have the two wires - one for your reverse wire and the other for ground. I've added a link to a video review for you to check out as well.

The TK71-755-00 replacement actuator I received has one blue wire as expected but also one white wire is this for a ground ?

Yes, you're exactly right. The product wast just recently updated by the manufacturer and we haven't yet been able to take new pictures - the white wire is indeed for ground.
