Took the ASPY dash apart. Took the wire harness cover off and disconnected the wire harness:
Took the front dash glass and faceplate off:
This "glass" will fit all the 1200 LCD displays. Four screws and the PCB comes out:
Two more screws and the odometer comes out. This pic shows the odometer with the small motor removed. The motor was removed to prove that the numbers were free to rotate:
Did the same for the '85 dash.
My test rig was a drill with a small common screwdriver bit that fit the front wheel speed sensor:
I attached the odometer motor to the '85 dash:
Tested to determine if the motor was U/S or not:
Key on, dash lit up, and using the drill in the speed sensor, the speed on the dash was indicated and the trip meter operated, but both odometer motors did not operate.
This indicates to me that the odometers should be good, but the odometer PCB circuit has failed somewhere. My expertise is not in PCB troubleshooting so another new to me dash is needed. Talking to my brother this morning and he suggested contacting the local college electronics department and ask if it could troubleshoot the PCB board and determine where the fault is, and if possible, replace the affected component.
I noticed when I first put the shelter on, and connected the travel computer to the system, that when I changed from Kilometers to miles, the dash indication changed but the fuel management system of the travel computer did not. The fuel management system of the travel computer works well in Kms so not a big issue, but would like to understand why the system does not change.
