The machine may "index" or turn slightly when starting and stopping. This condition can be caused if the left and right propel pumps neutral and initial current adjustments are not closely matched.Solution:
The pump matching adjustment procedure is performed as follows:1. Install two "Fluke" or equivalent multimeters to monitor the left and right propel pump forward EDC coil current. The left multimeter is to be connected in series with the left pump forward coil pin #10 at the propel MPC-10 controller 40 pin connector. This can be accomplished by disconnecting the wire at pin #10 and installing a test wire in pin #10 that leads to one side of the multimeter and connecting the other side of the meter to the wire removed from pin #10 thus putting the meter in series with the left forward EDC coil. The right forward EDC coil current is to be monitored at the same time using pin #33 at the propel MPC-10 connector by putting the meter in series with the right forward EDC coil similar to the procedure described for the left.2. Check the propel software version by viewing the MPC-10 display window while turning the key to the ON position, as the MPC-10 powers up "888" will flash once and then a three digit software I.D. number is flashed. Make note of this number.3. Start the engine, put the propel MPC-10 into calibrate mode "2", the MPC-10 will automatically increment to "c12", set the engine to high idle, propel lever forward, propel speed dial at 50%, pave range, parking brake released. After the propel status light is flashing, record the current values displayed on the multimeters for the left and right forward EDC coils, while the machine is in auto-calibration mode and light flashing.4. Machines that have version "220" propel software installed should display 16-21 milliamps for the left and right forward initial calibration current. Machines that have version "301" propel software or higher should first ramp up to 9-13 milliamps for the left and right forward initial calibration current, then drop off to zero next it will ramp up again this time to approximately 16-21 milliamps and hold while the propel status light flashes.5. If the initial calibration current does not fall within the above described ranges for the left or right pump adjustment will be required as described in step 6. If both pumps are within the initial calibration ranges skip to step 7.6. If one pump is within the initial current ranges indicated in step 4 and the other is not, adjust the out of range pump to match initial current as outlined in step 7. If both pumps are out of the initial current ranges indicated in step 4 both pumps will require adjustment as outlined in step 7.7. The pump neutral adjustment located on the main body of the EDC, ( locknut & threaded adjuster) requires 5/32 inch allen wrench and 1/2inch wrench, is adjusted as follows: If the
