I need some help troubleshooting my Hobbico Accu-Charger. This is the "old" black box version - not the new peak detector charger in a white box. When I select discharge for my four cell flight packs, the charger begins the discharge cycle, it continues for 5-10 minutes then switches to charge (indicating that the packs are discharged to 1.05 volts per cell, and ready to take a full charge). When I check the supposed fully discharged packs, they read 5.3 volts. When I perform the same discharge/charge cycle on my friend's identical Accu-Charger, it indicates that the packs have over 200 minutes left (not 5-10). I placed a DVM in the circuit with the pack while it was connected to the unit. The pack reads 5.3-5.4 volts. When I press the button to begin the discharge, the voltage drops to 4.3 volts. I have cleaned the slider switch that selects the number of cells (3, 4 or 5 cells) with tuner cleaner. Any suggestions from users of this unit or electrical savvy fliers?
