I have a CMM-1000 Type 4 which we purchased new about a decade and a half ago. The original batteries gradually degraded and I removed and recycled them several years back. At that time, everything was working fine except for the short run time between charges.
Yesterday, I cleaned the connectors with a wire brush and installed two PowerSonic 18AH batteries. The B&D wallwart charger lit the green LED when plugged in, and the charge on each battery came up approximately 0.3V overnight, so the charging circuit appears okay.
However, when the lockout pin is inserted, the “fuel gauge” meter gives no charge indication and the mover will not start. The motor turns freely by hand and the brushes appear to have about 50% wear left in them.
Could this be caused by corrosion on the switch contacts or perhaps a bad fuse? Any other ideas?
