Amps Reads +/- 509 AMPS or "OL" 2.

An open circuit or bad connection in one or both of the shunts for the associated battery, will cause Link 1000 to read its highest or lowest possible value for that battery, usually +/- 509 amps or "OL." To determine if the problem is with Link 1000 or in the system wiring, remove the shunt sense wires for the affected battery bank from the terminals on the back of Link 1000. Connect Link's terminals to each other and to the black wire terminal.

3. Read battery amps on Link 1000 for the affected battery. If the amps reading drops to zero, the problem is an open circuit or loose connection in the system wiring. If the amps reading does not go to zero (+/- 0.1 amp), contact Xantrex Customer Service for assistance.
