there should be 3 or four post's on it.1 of the little posts runs to the starting switch. if there is another little one,that runs to ground.one of the big posts runs derectly to the battery.the other big one to the starter. the starter SHOULD be grounded on the engine block if not,it will probably have a ground wire. to test the solenoid,turn the key to "start" (or press you're push buton,if no key) then there should be somewhere around the battery voltage going through the little post that is not ground...if not,you're switch is bad. but if you are getting current, try the post that runs to the starter. if that is also getting current(odviously while the button is pushed or the key is in "start" position) but you're not getting an engine turnover,then you're starter is bad. but if you don't get current through the starter post,check you're ground. it might be the little post next to the engagement post or, if there is only the engagement, check the metal-to-metal contact on the solenoid mount. if you are still not getting results, it is time for a new solenoid. and,also,before you go replacing the starter try taking out the spark plugs.sometimes there is just to much compression buildup.if it still doesent work,new starter!

Murray riding lawnmower solenoid test?

Assuming it is equipped with a Briggs & Stratton: Fuel solenoid test: Unclip wiring harness and remove solenoid from carburetor float bowl. Take a charged 9 volt battery, and touch two leads from the battery terminal to the solenoid terminals (polarity doesn't matter). You should hear an audible click as it engages, on some models you can actually see the solenoid plunger retract under power. If nothing happens, replace solenoid.

How do you test a dodge egr solenoid?

ok, here is a preliminary test. get an ohm meter aka continuity tester, unplug the solenoid from it's plug style connector. Look inside connector and you will see metal contacts or prongs. Plug your continuity tester leads on the metal prongs. continuity should be complete , another test that can be performed is to connect a 12volt power source up to the solenoid.......this will cause the mechanism to operate and the solenoid will "click" and do it's thing. good luck


How do you change a starter solenoid on a 1983 Chevy silverado?

I DO BELIEVE THE SOLENOID IS MOUNTED ON THE STARTER AND YOU WOULD HAVE TO REPLACE THE STARTER TO REPLACE THE SOLENOID remove the starter and take it down to your local auto parts store. they can bench test the starter and give you the proper solenoid if it needs to be replaced.


How do you test the solenoid on your lawn tractor?

take your multimeter and set it to volts, going into the solenoid you should have anywhere from 12.2 to 14v and coming out it should not drop anymore than 1 volt. If it does the solenoid has to much resistance and should be replaced


Test Solenoid for mtd 18hp brigg and stratton motor?

If you are trying to test your starter solenoid here is one way you can test it:Get a 12V test light from any auto parts store.With all these steps you will need to have someone seated on the mower, have the deck arm all the way in the up position and the clutch pedal all the way down. This should make all the safety switches activate and the solenoid should be working.1) Hook up the clip end to the "-" or Neg side of the battery, then touch the pointed end to the big post of the solenoid which has the battery cable from the battery. It should light up the test light. If it doesn't then you have a bad battery cable or a bad battery. If it does light up go to #2.2) With the clipped end on the Neg battery post, touch the pointed end to the other big post on the solenoid that has the cable going to the starter. While holding the test light on this post try to crank over the engine. If the test light lights up the solenoid is fine. You either have a bad cable to the starter, a bad starter or a bad ground in your system. If it does not light up go to #3.3) With the clipped end on the Neg battery post touch the small post of the solenoid. While holding the test light on this post try to crank over the engine. If the test light lights up then the ignition wiring to the solenoid is fine. If the solenoid has only one small post and the test light lights up here and not on the big post to the start then you have a bad solenoid. If it does not light up then you have a wiring problem other than the solenoid. It could be an ignition switch or a safety switch. If your solenoid has two small posts then one of them is a grounding post and we need to make sure you are getting a ground to activate the solenoid. If this is the issues go to #44) Hook the clipped end of your test light to the "+" or POS side of your battery and touch the pointed end of the test light to the second post and see if it lights up. If it doesn't then you have a wiring or safety switch issue.


How do you trouble shoot John deere Lt 155 solenoid?

I have a JD LT 155 C. I have replaced the solenoid and the mower still want start. There is 12 volts between the battery and the solenoid. When I test the voltage between the solenoid and the starter, the reading is 5 to 6 volts. Why is there a drop in the voltage to the starter?
