ACTIVE TECHNOLOGY IS WORKING WITH DOUBLETREE RV TO RECALL 359 ACTIBRAKE ELECTRIC-HYDRAULIC ACTUATOR, P/N AB-1-14, USED FOR HYDRAULIC DISC BRAKES INSTALLED AS ORIGINAL EQUIPMENT ON CERTAIN DOUBLETREE TRAILERS. THE TRAILER WIRING CONFIGURATION OF THE CIRCUIT BREAKER ALLOWS HIGH CURRENT TO BE CONTINUOUSLY APPLIED TO THE ACTIBRAKE EVEN AFTER THE TRAILER CIRCUIT BREAKER IS TRIPPED AND THE 30 AMP FUSE ON THE ACTIBRAKE IS BLOWN. THEREFORE THERE IS A SITUATION WHEREIN THE 50 AMP BREAKER IN THE TRAILER WIRING DOES NOT PROTECT THE ACTIBRAKE BATTERY CHARGER CIRCUIT FROM OVER-CURRENT.
