help needed to trouble shoot the 14 and/or 7 pin connector

[eyyu]

I have a 2008 S220, till now I never have the need to use either of the connectors. Now I got a 2015 angle broom for snow removal. I was able to spin the broom, but have no luck getting the cylinder that changes the angle to work. I tried all the button on my control (BTW, it's a hand control only unit). tested continuity of all wires from the engine bay where the 7 pin/14 pin connectors plus into the magnetically mounted black box all the way to where wires plug into the black box on the broom. At first, I suspected electrical issue with the new broom. Now I know that the machine is not sending out signals at all. Also, when I go to the attachment screen on my right controller on the ceiling, it says using the left foot pedal for angle control and I don't have any pedal. 1. I understand that the 7 pin is digital so I can't easily test it. 2. 14 pin is analog and 2 pins should get hot when I push either the left/right or cylinder in/out button on the joy stick. the test result is negative. that lead me to think something somewhere in the Bobcat is either not turned on, programmed, or simply broken. In order to figure that out, I need help from guys here either with the proper knowledge or/and point me to where I can get a copy of the electrical diagram of the machine. Thx a lot. Erwin

Spence an hour and half this morning thinking to troubleshoot from the computer input end (joy stick output). It turned out very disappointing. The left joy stick have 4 wires coming out of the top switch bundle that goes into the bottom of the servo into some circuits. the entire thing with 14 functions only have 4 wires going into the frame harness. So everything must be digital, no way to diagnose with traditional means. Will have to put everything back together and bring to Bobcat later this week. Erwin

Sadly the digital bit is beyond most of us, the attachment needs the suitable controller to work too, so if it's not a bobcat attachment, you can't use the 7 pin connector i believe.
I hope your dealer works it out for you easily.
