Question about Poulan 42-Inch Steel Deck 17.5 HP Briggs & Stratton I/C Engine With 6 Speed

1 Answer

Poulan Riding Mower won't crank, battery OK.

My Poulan HD145H42G 14.5 hp B&S 42 " won't fire. Battery seems ok. Not even a click when I turn switch. Seems like an open circuit on seat, blade or drive safety switch. Seat switch checks out ok. Still looking for the other 2 switches. Are they accessible without tearing the mower apart?

Could it be the solenoid? How do I check?

    I apparently had a bad/dirty connection because when I got in there to do the testing tried to get the solenoid out and retightened and it started right up. Worked 2 weeks and now it won't start again. But, this time it gives me some rapid clicks but the starter won't turn the flywheel. If I rotate the pully shaft by hand and then try to start, the starter energizes, engages the flywheel but only turns it a few degrees then starts clicking.
    If I turn the pully by hand and try the starter again it does the same thing. Voltmeter on the solenoid/starter wire to ground shows only about 1 Volt when the key is turned.

Forget the safety switches for now.The first thing I would check would be the fuse. It will be located on the battery side of the solenoid. Follow your positive battery cable to the solenoid. There will be a small red wire coming off of that post with an inline fuse. If the fuse is good, check your solenoid. There are two wires plugged into spade terminals at the bottom of the solenoid. Unplug the one that is insulated, the other one is a ground. Hook a test light from that wire to ground. When you turn the key to start (with the brake pedal held down), it should light. If it lights, your solenoid is bad. If not, then you can start looking at switches. Probably will be one of the two. Hope this helps. Dwain

    Now, that rapid clicking is usually a sign of a low battery or corroded terminals on the battery. From what you're saying, you're turning the engine past the compression stroke, then the starter will turn the engine till it hits the compression stroke again. Make sure your battery is up. Wiggling wires does sometimes fix It's happened to me more than once. Sometimes I'm not sure what I did, but things will start working again. It's usually corrosion on terminals and moving them sometimes regains connection, particularly on the ignition switch. You still could have a faulty solenoid. You should show the same volts on the live wire at the bottom of the solenoid (when unplugged) and ign. switch is turned to start, as you have on the battery.

Check the battery voltage with a multimeter. It is possibly low. If so, you can try to charge it. At your own risk, you can attempt to "jump" the mower battery with a car battery. I don't advise this as a common practice. They both are 12 volts, the difference is in the amount of CCA available (Cold Cranking Amps).

Replace the battery. Even though the battery may say it's good, it doesn't have enough of cranking amps. Go purchase a battery with 350 cranking amps. This will fix your problem. The battery power isn't enough to kick the starter completely up to turn the engine.

Even new batteries can be bad. All it take is one dead cell in it and it won't be enough to start the mower. The other thing to look at is the cranking amps of the battery. The cheapest wally world battery won't cut it for the larger motors.
