| Got a spare timer from Gunn in 2000. When it looked like the old timer taking too long to finish a cycle installed the new one, mowed and then put the pack on charge at 8pm yesterday , at the 3-5 yr mark. Surprised to see charger still working at 9 this morning. The pack charged to 44v but the timer knob never moved from the 3-5 mark. Is there a calibration procedure for the timer? Maybe I mis-wired. Help please, Jack |
