Discrepancy: Cockpit DC amp meter will not indicate load when selected to battery position. All other positions indicate normal.
Possible fix: Replace broken terminal end for load meter shunt wire, located inside battery connector.
Tip: You must remove power and disconnect battery connector and separate halves of connector to install a new teminal end for the shunt wire.
Reason: a 22 gauge wire, connected to the negative lug inside the battery connector supplies current to load meter shunt which in turn provides battery load amps indication to DC amp meter, on the P-5 panel when selected to BATT position.
