Description
This error is associated with eddy
current EFX’s. The resistance (brake) control system
constantly monitors the amount of
current being demanded by the eddy current magnet. Error 50
indicates that amount of current
being demanded by the eddy current magnet is excessive.
Possible
Causes
1. The most common cause of this
error is shorted or damaged wiring between the lower PCA
and the eddy current magnet.
2. The eddy current magnet is bad
3. The lower PCA is bad.
Possible
Remedies
1. Carefully check the eddy current
wiring and connections, ensure that the wires are not
shorted together or shorted to the
EFX frame. Repair or replace the damaged wiring as
appropriate.
2. Remove the wires from the eddy
current magnet. With an ohmmeter, measure across the
eddy current magnets terminals. The
ohmmeter should read approximately 100 ohms. If the
reading is significantly low,
replace the eddy current magnet. Measure between each eddy
current magnet terminal and frame
ground. Both readings should be infinite (open). If either
reading is significantly low,
replace the eddy current magnet.
3. If both the eddy current magnet
wiring and the eddy current magnet are good (as tested
above),
replace the lower PCA.
