THE TRUCK WAS SITTING IN THE GARAGE AT WORK WHEN SMOKE STARTED POURING OUT AROUND THE HOOD. I RAISED THE HOOD TO FIND THE SPEED DE-ACTIVATION SWITCH ON FIRE.I PUT OUT THE FIRE. AND PURCHASED A NEW SWITCH FROM 32 FORD IN BATAVIA OHIO, AND INSTALLED IT.32 FORD ADVISED ME TO CALL FORD AND MAKE THEM AWARE OF THE PROBLEM WITH THE OLDER TRUCKS , WHICH I DID TO NO AVAIL,AS THEY JUST PASSED ME BACK AND FORTH , AND NO ONE WOULD LISTEN TO WHAT I HAD TO SAY. ALL I WANT IS TO WARN THEM ABOUT THE PROBLEM IN THE OLDER MODEL TRUCKS. THEY HAVE FIRE HAZARD. WE WERE JUST LUCKY THAT WE WERE AT WORK WHEN IT HAPPENED OR IT WOULD HAVE BURNED OUR CO. HIGHWAY GARAGE DOWN. THANK YOU NEIL MORRISON GARAGE SUPERINTENDENT ADAMS CO. HIGHWAY DEPT.*AK
