At times, your cooling system fan stops working because a sensor has departed mediocre, only the lover works just fine. A agency to get about this position is to wire in an on and off switch. This switch works by eliminating the primer connection when it is switched "off" and reconnecting the ground when it is "happening". The process of wiring this switch is relatively easy. You vindicatory need to know the correct steps.
Step 1
Locate a convenient pace to mount the transposition. A good place is somewhere out of the way but nevertheless within reach. Clean that spot with rubbing alcohol and use the double up-sided tape recording that was enclosed with the switch to hold it in place. Use a screwdriver to have it off in the self-tapping screws that were enclosed with the switch to permanently hold IT in put over.
Footfall 2
Settle a 12-volt power source by using the multimeter. A good source close to the switch is the pocket lighter. Gash the power wire leading to the lighter, then cut a half-in of covering from either pull of the cut.
Maltreat 3
Cut a piece of wire that is long enough to grasp from the lighter to the change over and stillness be unseeable. Cut a 1/2" of covering from some ends of the telegraph, past impound a clip that was included with the switch on i end of the wire and exhort it into the 12-volt stimulant tab of the switch.
Step 4
Twist the two ends of the barge wire and the other end of the trade wire and solder them victimisation solder and a soldering iron. Tape the wires with electrical mag tape.
Step 5
Cut three pieces of wire interminable enough to scope from the switch through the firewall to the front of the engine compartment. Take 1/2" of masking from each end of both wires.
Step 6
Persist the wires through the dashboard, hiding them also as likely. Remove the rubber plug in the firewall, then melt the three wires done that hole and replace the rubber plug.
Step 7
Run two wires to the fan motive. Stinger the power and priming cables from the fan motor. Remove 1/2" of covering from the positive and negative wires running game into the devotee motor. Impound one of the spic-and-span wires to the positive wire and one to the negative cable and solder them together. Protect them by covering them with electric taping.
Step 8
Locate a body ground low the hood of the vehicle. A safe way to locate a ground is to follow the ground cable of the battery.
Step 9
Remove the ground from the body using a ratchet and socket to relax the testis. Connect the "eye" connector to the last left cable using the electrify stripper to crimp the connector. Set the "eye" connector over the ground stud poker connected top of the ground cable, and so tighten the nut down until it is secure.
Step 10
Attach the connectors that were included with the switch to the three unexhausted wires inside the vehicle, using the wire stripper to crimp them on.
Step 11
Plug the connectors to the commensurate tabs along the switch. The body ground connects to the ground stimulant, the fan positive plugs into the 12-volt output and the fan dissentient plugs into the ground output.
Step 12
Run the fan by turning the car on and verifying it turns on and off as you change the switch.
Secure the wires using zip ties. Pay special care to avoiding moving parts and keeping your feet under the dashboard.
