4.0 Troubleshooting
Be sure all connections to the cage are correct. Check polarities. Check for loose connections. Be sure
all units are locked into place. Check for correct AC input and DC output voltages.
There are no user serviceable parts internal to the A86B. Should the A86B stop operating correctly,
contact the La Marche service department for a Returned Material Authorization (RMA) number and
return the rectifier for repair.
To avoid damage caused by shipping, the units should be returned in their original shipping container
with the original packing material, if available. La Marche will not be responsible for damage when
returned to factory.
