Precor efx 546 shuts off when I need to reverse direction during a workout also, the sliding is not smooth (very difficult to push the pedals on an easy level)

Procedure 6.4 - Troubleshooting the Generator
The generator performs three functions in the EFX. First, by controlling the amount of electrical
load applied to the generator, the user's pedalling resistance is controlled. Second, the generator
is used to charge the EFX's internal battery. Lastly, one of the generators six phase output
windings is monitored to determine when the unit is in use and when it is idle. This system also
determines the stride rate by determining the operating speed (output frequency) of the
monitored generator winding.
Warning
Because this is a self powered unit, it will either be necessary to either equip the unit with the
optional external power supply or have an assistant pedal on the unit while voltage
measurements are being taken. Because of the danger of working on the unit while it is in motion
using the optional external power supply is strongly recommended.
1. Perform the generator resistance test per Procedure 5.1. If any of the resistance
measurements are significantly high or significantly low, replace the generator.
2. The following voltage reading must be taken while the unit is in motion. Extreme care must
be taken to keep meter leads, hands, etc. clear of all moving parts. Using an AC voltmeter,
measure the voltage between 1 & 3, 2 & 3, 5 & 7 and 6 & 7 on J1 of the lower PCA. All AC
voltage readings will vary depending on the unit's stride rate at the time the measurement is
taken. At a stride rate of 100 strides per minute, all three voltage readings will be
approximately 100 VAC -110 VAC.
3. If any of the six readings in step 2 are significantly low, replace the generator.
