Do you guys run one set of leads of a 3 bank charger to the starting battery and the other 2 to the TM batteries in a 24 volt system? I'm having an interference issue when running my MG Digital tour while using structure scan. A guy in the Lowrance forum suggested the leads connected to the starting battery which powers my HDS 9 Gen 2 could be linking the TM batteries to the starting battery and causing the interference. The charger is a BPS XPS 3x5 amp charger.
