2. Is there a minimum of 36Vdc at Pin 7 of the 14 Pin connector of the IDrive?
NO, defective controller.
YES, Go to Step 3.
3. Is there a minimum of 36Vdc at Pin 5 of the 14 Pin connector of the IDrive with the Key
Switch turned "ON"?
NO, If not, check for voltage at the input of the IDrive Key Relay and / or the Key Switch.
There should be 36Vdc across the input of the IDrive Key Relay with the Key Switch turned
"ON". If not, check the Key Switch and / or wiring.
YES, Go to Step 4.
Note:
All measurements below should be taken with the "Key Switch" turned "ON".
4. Is there 5.0Vdc between Pin 2 and Pin 8?
NO, defective IDrive.
YES, Go to Step 5.
5. Is there 0Vdc to 5.0Vdc between Pin 8 and Pin 1 with either "Forward" engaged?
NO, check the Forward Switches, Potentiometer and / or wiring.
YES, Go to Step 6.
6. Is there 0Vdc at Pin 6 of the 14 Pin connector of the IDrive with the Burnisher on the floor and
2.5Vdc with the Burnisher tilted back on the "Stops"?
NO, if there is 2.5Vdc there all the time the Tilt Switch is defective and / or wiring. If there is
0Vdc there all the time, then disconnect the Tilt Switch to see if the voltage goes to 2.5Vdc, if
the voltage does not return to 2.5Vdc the IDrive is defective.
YES, Go to Step 7.
7. Is there 2.5Vdc on Pin 12 of the 14 Pin connector of the IDrive with the "Reverse" Button not
depressed? If not, defective IDrive. This voltage should go to 0Vdc when the "Reverse" Button
is depressed.
NO, defective Reverse Button and / or wiring.
YES, Go to Step 8.
8. Is there 10.5Vdc on Pin 10 of the 14 Pin connector of the IDrive, which is the input to the
Battery Meter on the Control Panel?
NO, defective IDrive.
YES, Go to Step 9.
9. Is there 36.0Vdc at Pin 2 of the 2 Pin connector of the IDrive with the "Pad Switch" turned
"ON" and with the traverse not engaged? If not, check the Pad Solenoid, Pad Switch and / or
wiring. This voltage should go to 0Vdc when the Forward traverse is selected.
NO, defective IDrive.
YES, Go to Step 10.
10. Is there 0Vdc to 36Vdc at the Motor Output on the IDrive when the Forward Traverse is
engaged? Is there 0Vdc to 24Vdc at the Motor Output on the IDrive when the Reverse Traverse
is engaged?
NO, defective IDrive.
