SOURCE: The ramp will not go up or down. It's states low

The ramp system has a battery monitoring system. If the battery voltage falls below 11 Vdc when the ramp movement is initiated or the battery voltage falls below 10 Vdc after ramp movement has been initiated, ramp movement will be stopped and gives that error message. The ramp will not be enabled until such time as the battery voltage exceeds the above limits. The battery voltage must be raised to be to correct this problem either by charging or replacing the battery.

SOURCE: precor efx 5.17 which intermittantly stops counting strides and freezes the display

please follow this steps:
Step 1

Remove the bolts or screws securing the console to the upright assembly. Lift the console and confirm that the cable connections are secure. Remove the cover from the console's battery bay and install a fresh set of batteries. Replace the battery cover.
Step 2

Detach the ends of the pedals from the crank axles. Remove the left and right disc shields and side shields. Inspect the interior of the base unit and locate the flywheel.
Step 3

Inspect the flywheel as it turns. Locate the magnet installed on the flywheel. Turn the flywheel until the magnet passes in front of the nearby reed switch. Loosen the screw securing the switch in place. Rotate the switch to reduce the gap between it and the magnet. Tighten the screw.

God bless you

How to fix the display

Start with verifying the battery voltage. Here is a video on how to do this. If your battery checks out, move on to the stride sensor gapping. I will post a link with a service bulletin that shows the stride sensor and it's location. Also, confirm the right crank arm still has the magnet on the backside.

Why is the Precor AMT 100i Adaptive Motion Trainer Elliptical primary belt making noise and should I adjust it?

SOmetimes belts make noise when they are worn out and need to be replaced - belts like that are considered 'wear' items, like tires on a car - they have a very limited lifespan compared to the other parts.

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.
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.

I was using the ellipitical and heard a loud pop sound. Now the cross ramp will not adjust. Any ideas on what is wrong? Also, how expensive would it be to fix?

i think you blow elevation capacitors or something was on the way ramp

but first thing check fuse on control board which is most common problem

it is located under rear hood you will see brown fuses marked F1 and F2 check both (mark where they belong they are same as round pills but red or brown)
