During the course of the investigation, road rescue discovered that the electrical system was not properly protected against a short circuitand the fuses would need to be changed to a fuse that requires a manual reset, instead of the automatic resetting type fuse currently installed in the subject vehicles.road rescue has filed a saftey recall to replace the fuses on all ambulances utilizing the self-resetting style fuse.a copy of the recall is attached and this action resolves the fire concern raised by this investigation.hence, this investigation is closed
