What was found
THE NEW BATTERY PACKS USED BY GRIMES WHICH ARE MFG'D BY E.A.C., USE A METAL STRAP BETWEEN POSITIVE AND NEGATIVE TERMINALS WITH A SMALL PIECE OF HEAT SHRINK ON THEM. THE PROBLEM IS THE HEAT SHRINK SHRINKS AT TEMPERATURE AND THE STRAPS CUT THE HEAT SHRINK AND SHORT THE TERMINALS TO THE BATTERY CAUSING SHORTS AND THE PACKS OVERHEAT.
