A poor starter solenoid can be discovered by a channels of elimination.
There can be cipher exceeding frustrating that sitting in your vehicle, turning the ignition primary and hearing a clicking sound or naught at all. There can be a unit of reasons for a no-start action, and some of them can be actually cinch to remedy. Among other candidates, the starter solenoid Testament extremity controversy. By reason of the starter solenoid uses a high-voltage Attractive relay to transfer electricity from the ignition solution to the starter, it can be the feasible produce of a starting complication.
Instructions
1. Field the vehicle in stadium or impartial with the emergency brake locate. Green light the battery connected for momentarily. Applicability a floor jack to lift vehicle colossal Sufficiently to deposit two jack stands under the front object of the frame near Everyone shove. Lift the rear of the vehicle and abode two jack stands under the rear factor of the frame near Everyone turn.
2. Research the battery voltage with a voltmeter by placing the bloodshot worthy voltmeter prompt on the affirmative battery terminal. Berth the dingy annulling probe on the absent battery terminal. You should announce at least 12.5 volts on the metre. The gloss does not corner to be on or in the start position for this proof. Charge the battery to abundant faculty provided it reads low.
3. Slide into the Chauffeur's seat and turn the principal to the "on" position. Comment the brightness of the sprint indicator lights. Turn the ignition gloss to the "start" position and notice if the indicator lights dim while you do so. If they dim, it means your ignition switch has made correct contact.
4. Slide under the vehicle with the voltmeter. Remove any splash guard if it impedes access to the starter solenoid. You will see a very thick wire and one small spade push-on wire. Choose the small wire. In the case of a fuel-injected engine, there will be three wires--one thick, one medium (spade) and one smaller spade wire. Choose the medium-size wire.
5. Remove the medium-size (or small-size) wire and place the voltmeter positive probe inside the wire jack. Place the negative probe of the voltmeter on a good ground source like the frame. Check the main fuse block for a defective relay or starter fuse, and replace if necessary.6. Stare at the two largest posts on the back of the solenoid. Have your assistant turn the ignition key to the "start" position. You should read 12 volts at the wire. If not, the wire needs to be looked at from the solenoid location up to the ignition key source for any breaks or disconnects.
The largest one comes from the battery and will be red. Pick the second-largest post. Take a jumper wire and connect the two posts momentarily. You will see a spark arc, but that will be normal. If the starter motor spins, it means the starter motor has engaged and works properly.
7. Stare at the same two large posts you just jumped. One of them has a thick braided wire running from it to the starter. Stick the positive lead of the voltmeter into the braided wire and ground the negative voltmeter lead against the frame or starter motor housing.
8. Have your assistant turn the key to the start position. You should hear a heavy clunk, then hear the starter motor engage and crank the engine, while you read 12 volts from the braided wire. If the starter does not activate to crank the engine and you do not read 12 volts at the positive lead, the solenoid has shorted and needs to be replaced.
