Burned Fuse Connector Test
Your car has many fuses, some
protect a small system like a
rear windshield wiper
while others protect major system circuits, like the
engine management system.
The primary purpose of an electrical fuse
is to help protect a circuit from damage in the event of a short. A fuse is designed
to break stopping the voltage flow in the event of a power overload or short circuit.
Each vehicle has several fuses that are necessary to safe guard
electrical circuits. An
electrical circuit will always fail at the point of highest resistance. Most of
the time that point is the fuse holder. If an electrical circuit fails, an
electric
window system (for example) the first thing you should check is the fuse.
Repair Guide
Step 1 - Remove the fuse and inspect, does it have signs of
extreme heat, possibly even melted? If so you have a burned fuse holder. This condition
occurs because fuses are subject to vibration and moisture. Once the fuse is replaced
the situation will occur again because the fuse holder receptacles are burned and
will create high resistance.
To check for this condition remove the fuse of the circuit involved and using
a flash light inspect the fuse holder receptacles with the plastic around them,
if they are melted and discolored they need to be replaced. There are two ways to
go at this point, you can replace the fuse panel or locate the wires involve using
a wiring schematic
and create a new fuse component outside of the fuse panel. I have done this many
times and it works very well.
Step 2 - Sometimes a burned fuse holder is not always easy to detect, in this case remove the fuse of the circuit in question and replace it with a new one. Next with the key in the "on" position move the fuse in and out of the fuse holder and note the effected device such as electric windows. If the device starts working while moving the fuse in and out, you have a burned fuse holder and a repair is needed. If further assistance is needed, our certified car repair technicians are ready to answer your car questions. Related Car Repair Information
