Hi, i need to know what color wire supplies power to the auxiliary thumb switch. I have 4 wires, purple, brown, yellow and green
Need a Serial Number to identify the correct schematic for a kickoff. Also it is better to identify the wire colours/numbers from the machine side of the harness. IIRC there are only 3 wires to the machine side of the 12-pin connector but 4 wires on the thumbwheel switch side. Problems with the thumbwheel operation.?
Serial # is CAT0287BAZSA01210
OK. With the ley OFF locate the 12-pin connector (CONN 33) underneath the joystick and unplug it. 1. Turn the key ON and measure the voltage between Pins 1 & 2 (wires P994 Blue & P997 Brown). It should be 8.0 ± 0.2 volts. 2. Turn off the key and reconnect CONN 33. Turn the key on and measure the voltage again between Pin 1 & 2 by back-probing into the connector. Confirm that it is the same as Step 1. 3. With the key ON and the thumbwheel in the centre measure the voltage between Pins 3 & 2 (wires P996 Green & P997 Brown) at CONN 33. 4. Repeat Step 3 with the thumbwheel rolled all the way forward. 5. Repeat Step 3 with the thumbwheel rolled all the way back. Post the results from Steps 1-5 back here.
CAT0287BAZSA001210
Which colored line of the thumb switch supplies power to it
See the sketch attached to Post #4 above. The information and test procedure is all there.
THank you very much
Once you have the results from all the tests post them back here. We’ll be able to tell from them If your switch is good or bad.
Ok will do. Thanks again. do ,
