Jod Bronson: Another way is to Hook a Battery or 12V Car Charger at BOOST 50AMPS directly with a Car Jumper Cable to the FRAME (NEGATIVE CLAMP) and the POSITIVE CLAMP directly to the STARTER POSITIVE to see if it will Spin :))). Also, I just bought a NEW Solenoid for $7.85 including Shipping (2016 Price). Save time and Money, just JUNK it... LOL. Good TESTING Video tho :)))
A Bernard: Great Video. Had a 99 John Deere LT 155 with a non-crank situation. Checked the battery first, key switch, (another video) then the solenoid and got 12 volts exactly as noted. Once this was good followed another video of yours regarding testing the safety switches. The brake safety switch tested good but had dirty connections.That is all it was. Thanks!
Jim Burns, Jr.: Great video... professional n clean... thank you very much
Get Right: I just wanted to thank you for this video! I cleaned up the ground connection on my 3 pole solenoid and my mower started the first time!!
Patrick Lilley: too much info...
malligator: Do you think that you could learn to properly pronounce the English language? It is not s sill-in-oid. It is a SOLinoid. Drives me nuts!
Finn Campeau: I replaced the siloanoid a while ago now it works but it only works some times so I looked to see if there was a lose wire there was not so I sprayed it with where cleaner it still has the same problem
Marcia Schilreff: Im kinda in the same situation as Robin Wrobel that posted a year ago. New starter, new solenoid, new battery, checked the safety switches...replace the blade switch and still nothing. Im thinking a ground for the solenoid, but not sure if the 4th post should be grounded specifically to something.
Edgar Trejo: I've checked all the cables and the fuse blew out
healthed: Have a craftsman riding mower, won't start. Makes a clicking noise or whining noise when trying to start. Tested solenoid, 12 volts coming into solenoid from battery and none going out to starter. Put new solenoid on and same thing, no start and 12 volts coming in and none going out. Will a bad ignition switch cause this problem? If not, what could be the problem? Please help, trying to fix this to save money.
Kienfee: Performed all the checks and I found my problem to be a defective blade safety switch that would not allow the engine to start. Thanks for the Help!
Bob Allen: Excellent video! Many thanks.................
Hexus Dominus: So basically here is the bottomline: For a 4 post Solenoid lets say Post 1 and Post 2 are the ones he is putting the batteries to test. These are the two posts that a black/purple wire clips on and off. You can pull those out easily on the mower. Next is Post 3 which goes to starter. Post 4 is directly connected to Positive of MOWER battery.
Test: Connect Post 3 with Post 4 directly - with a screwdriver or wire and see if starter cranks. If it does then both battery and starter is good. Lets assume starter and battery is good.
Case 1. With Key in ON position if you have 12 V across Post 1 and 2 (test with Multimeter) and starter wont start then you have a bad solenoid. As this guy in the video correctly explains you should have continuity between Post 3 and 4 when there is 12 V between Post 1 and 2. With a working solenoid this would mean a 12 V between Post 1 and 2 with key on ON - this would connect Post 3 with Post 4. Post 4 is live battery from mower and with continuity Post 3 would connect to 4 and would become live and start the starter. So with a bad solenoid you would have 12 V with Key ON and no continuity between Post 3 and 4.
Case 2. With Key in ON position if you DO NOT have 12 V across Post 1 and 2 this means Solenoid is not getting the power to close the switch or provide continuity between Post 3 and 4. This does not say anything about the solenoid. Could be good or bad. But tells you that you have problems elsewhere with 1. Loose connections. 2. Bad wires. 3. Bad Seat switch 4. Bad RIO switch. 5. Bad Brake/Clutch Switch 6. Bad IGNITION/KEY switch 7. Bad Blade Engagement Switch. Fix all those until you get 12V across the top posts of the Solenoid or Post 1 and Post 2.
Janine Montgomery: I have a Honda Harmony 2013 riding mower, unsure what year. Th battery is charged, hit the key, and it'll take 2 or 3 attempts to turn over. Once turned over, it turns slow for 2-3 seconds then started gear kicks down. Eventually it might start. Can anyone tell me what to check? thank you.
Mitchel List: how come my yard machine doesn't work without a jump start
Charles Martin: great job explaining this
billy ashley: i have a Poulan Pro Lawn Mower I have a 4 Pole starter solenoid are you supposed to have power on the black wires on the solenoid if not does that mean I have a short on the solenoid thanks Billy
Bob O: Which wire do you test on a 4-pole solenoid? thx
