Things Needed
Virtually every MTD ride mower with a battery and keyed kindling system can be calleda solenoid mower . This is because the electric start function needs a solenoid to engage properly . For MTD riding mowers and nigh every other electrically begin fomite , a solenoid will be an integral part of the ignition circuit . All solenoids act like an electromagnetic electric switch . When the ignition has been activated , the solenoid close up the circuit and allow force to the starter . If the freshman does not answer when the ignition is turn to the " jump " position , the first thing to do is to troubleshoot the solenoid .
Step 1
turn up the solenoid on your MTD rag lawn mower . get to the goon and witness the positive or red cable that arrive off the barrage fire . The red barrage fire cable will begin at the battery and destruction at an electrical Charles William Post attached to the solenoid .
Step 2
Locate the starter cable television service . This will be a large blood-red cable , similar to the battery cable , that will be connected to the other electric post on the solenoid . This cable guide instantly to the fledgeling , and ask to be take from the solenoid electric post with a proper sized wrench . Although there may be other cable television service or wire attached to the solenoid , they will be smaller than the great battery and starter cable and can last out attached .
Step 3
Adjust your multimeter gear up to 20 volts DC . call on the ignition replacement on the rider to the " on " position . Touch or crop the black or ground investigation on your multimeter to the chassis . Touch or clip the red or positivistic investigation to the post where the battery cable television service remain connected , and swan that the multimeter is now scan 12 V .
Step 4
Disconnect or bump off the carmine probe from the barrage fire side on the solenoid . Clip or touch the flushed probe to the side of the solenoid where the starter cable has been removed . Activate the start chronological succession by turning the ignition system to the " start " position , and read the emf on the multimeter . If the solenoid is good , you will read 12 volt on the multimeter . If there is a zero voltage reading on the multimeter , the solenoid is down and necessitate to be replaced .
Tip
Backyard auto-mechanic have a little trick they use to test a potentially bad solenoid . The ignition is switched the the " start " position , and the solenoid is lightly tapped with a hammer or a pull . Oftentimes , the tapping will actuate the electromagnetic switch inside of the solenoid , which will complete the racing circuit and earmark the mower to start .
