As the first stage passes the proximity switch at the bottom of the mast assembly the extend function becomes inop. Extend works fine as the carriage is in the first stage. Cluster reads extend. Hoses pressurize for retract and extend. Battery water level is good. Battery voltage is good at 24v. Not sure if it's a signal issue. Proximity switch was replaced and lost all functions. Reinstalled previous switch and back to square one all functions work except for extend after first stage leaves. Any information would be appreciated. Thanks so much.
update: mast harness fixed the issue. thanks so much.
