Hmm?. a couple more questions: Did you use the ABS amigo to clear the codes after the repair? (I hope this isn?t a dumb question.) If not and it is logged as a ?hard? fault, then the amigos will appear until it?s cleared.yuenie said:Yes, the code is 114 Shuttle Valve Electrical Failure. I just had my ABS Amigo 2 days ago. The amigo is a HARD one. The 3 annoying guys are ALWAYS there, not intermittently.
I also bought the same trailer connector. The only difference is I haven't soldered but just tied up the copper wires because my soldering thing is not working. Another thing I suspect is the ground. I clipped it to the metal holder of the steering reservoir instead of the bolt in the write-up. It's because the bolt head is rusted and rounded.
Is there any electrical test I can perform WITHOUT TAKING OUT THE SHUTTLE VALVE again? It is a pain of removing the 3 screws.
The metal holder of the steering fluid reservoir is painted, as I recall, and unless you get down to bare metal, you won?t have a complete ground. You can use your multi-meter (I assume you have one and tested the shuttle valve switches while they were out to make sure they are within spec) to find a good ground by connecting red lead to live + battery 12v and then test for a completed circuit with the black lead to a potential ground point. According to Josh, write-up author, any ground will theoretically work.
Since the SLABS computer is monitoring electrical resistance, I think soldering is important to make sure you have a good solid connection that doesn?t affect resistance.
I don?t think there is anyway to test the shuttle valve switches without removing them; you need to hold each one then both down to simulate their function while measuring resistance.
