Takeuchi TL12V2 Quick Attach Problem

[Quinc108]

Only one circuit on my Quick Attach is working - by default the unlock switch works. To lock I have to switch the couplers that are midline between the switch and cylinder, press the unlock, and it will lock. I have tested continuity and everything is good from the switch forward - fuse is good, solenoid is good, switch is good, and the line is good all the way to the back of the machine and presumably to the relay box in the back. I'm Just not getting power to the lock side. I'm guessing a bad relay in the box in the back, but before I pull out the radiator to go back there I want to ask if anyone has encountered this or has any specific ideas direction regarding that box. Thanks!

I don't have any experience with your Tak but won't it be easier to start with the switch?
Good luck, that's a royal pita to go through just to change the attachment.

As I said in the post the switch is good. I tested it.

There's not a ton of ctl talk here in general, then machine specific makes it less likely. Hopefully you'll get lucky.

They dont use a standard relay? Either way I would try swapping relays. After that make sure your getting power from the switch and constant power on the high amp side. Of relay.
