NHTSA complaint: 1993 MAZDA MPV — ELECTRICAL SYSTEM
I COULD NOT RECOGNIZE ANY PRIOR SYMPTOMS OTHER THAN POSSIBLY RELATING TO AN ENGINE KNOCK WHEN THE WIRE GETS VERY HOT BEFORE IGNITION SWITCH SOCKET HAS REPEATEDLY MELTED SINCE THAN. I HAVE TORN OPEN AND INSPECTED EACH INDIVIDUAL WIRE IN THE MAIN HARNESS IN THE ENGINE COMPARTMENT, THE ENTIRE DASH AND EVEN WENT AS FAR AS SEPARATING THE FUSE BLOCK FOR A POSSIBLE SHORT THERE. I HAVE PUT IT IN SHOPS AND NO ONE HAS FOUND ANYTHING WRONG TO CAUSE IT. *TR
