EQUIPMENT DESCRIPTION: ELECTRIC STEP CONTROLS SERIAL NOS. 93,822-103,007 SOLD BY KWIKEE AS ORIGINAL REPLACEMENT EQUIPMENT TO RECREATIONAL VEHICLE MANUFACTURERS AND VAN CONVERTERS BETWEEN JULY 17 AND OCTOBER 1, 2000. PARTS IN THIS RANGE MAY ALSO HAVE BEEN AVAILABLE TO REPAIR SHOPS AND END USE CUSTOMERS DURING THE SAME DATES. THESE STEP CONTROLS (BLACK BOX ONLY) WERE IMPROPERLY ASSEMBLED BY SUBSTITUTING A FUSE (IN PLACE OF A DIODE) ON THE PORCH LAMP CIRCUIT. THE PORCH LIGHT CIRCUIT EXITS THE CONTROL THROUGH A PURPLE WIRE ON THE POTTED SIDE OF THE CONTROL. THE PORCH LIGHT/PURPLE WIRE CONNECTION GIVES THE MANUFACTURERS THE OPTION OF ILLUMINATING THE UNDER STEP LIGHT THROUGH A SWITCH MOUNTED INSIDE THE VEHICLE. THE SUBSTITUTION OF A FUSE FOR THE INTENDED DIODE MAY CAUSE THE STEP TO INADVERTENTLY RETRACT WHEN THE PORCH LIGHT IS TURNED ON.
