Poulan Pro Mower Won’t Start & Has No Crank (SOLVED)

In order to turn over the engine of an electric start mower, power must be supplied to the starter motor. In the event that the engine won’t turn over, check first to see if anything is blocking the starter from receiving the power it requires.

A weak battery, loose wiring and components, a blown fuse, a defective ignition switch, a faulty safety switch, a faulty starter solenoid, or a malfunctioning starter motor are all reasons why your Poulan Pro lawn mower won’t turn over or crank.

Take the black negative cable out of the battery before attempting any electrical repairs. Prevent harm by using safety equipment. The operator’s manual for your Poulan Pro contains important safety information.

Before diagnosing, repairing, or operating, be sure you’ve read and understood all of the safety recommendations in the equipment’s operator’s manual.

In the event that you lack the necessary expertise, experience, or physical ability to properly complete the repair, it is recommended that you seek the assistance of a professional.

Why Does Your Poulan Pro Mower Not Start?

Your Poulan Pro’s Battery Is Dead or Faulty

It is impossible to start the engine with a poor battery or one that will not hold a charge.

If you want your battery to last as long as possible, charge it as little as possible. This is crucial information to have before stowing the lawnmower and batteries.

In cold conditions, a battery that has not been fully charged can freeze and become damaged. Follow the instructions below to check your battery:

To charge your 12-volt battery, you should use a battery charger. Please safeguard your eyes and skin from potential electrical shock by donning protective clothing before proceeding. To charge the battery on your lawn mower, do the following:

  • Get at the terminals and batteries. Sometimes, a screwdriver is required to access the battery. Never take the battery out of its housing.
  • The positive cable should be plugged in first when connecting the charging cables. It’s the plus-sign cable, sometimes known as the red one. Put the plug into the battery’s positive terminal.
  • Put the negative end of the cable into the battery’s negative port. Alternatively, this is the negative-sign cable, which is black.
  • To avoid electrocution, avoid touching anything that isn’t covered in rubber.
  • Input the desired voltage and current into the charger. Lawn mower batteries typically have a voltage of 12 volts. More current speeds up the battery’s charging process. Power consumption should ideally begin at 2 amps and rise to no more than 10 amps. Ideally, the charge should be applied gradually.

There needs to be a new battery installed if the old one can’t keep a charge. Every automobile shop, hardware store, or lawn mower dealership should carry replacement batteries.

Make sure to bring in your worn out batteries. Without your previous battery, most stores will have to charge you a core fee.

Worn Out Poulan Pro or Loose Connections

The vibration of the Poulan Pro mower could cause the wiring and electrical components to come loose. Go over the connections and make sure everything is in good shape.

Determine if there is any rust or corrosion on the parts because of water. Removing corrosion is necessary to ensure the system’s smooth operation.

To begin cleaning the parts, disconnect the battery wires. A wire brush and baking soda solution can then be used to scrub away the rust (2 cups water to 3 heaping tablespoons of baking soda).

If you can’t get the terminals clean, or if other parts are corroded beyond repair, you should replace them.

Your Poulan Pro Lawn Mower Has a Blown Fuse

To prevent damage to your Poulan Pro from electrical surges or shorts, a fuse has been placed.

There could be a blown fuse in your mower, so check it out. If you’re not sure if the fuse has blown, you can test it by touching one probe from a multimeter to each of the prongs.

Having a resistance value close to 0 indicates a good fuse. A blown fuse is indicated by a resistance value of infinity.

When replacing a blown fuse, use a fuse with the same amperage rating. If your Poulan Pro keeps blowing fuses, you should take it to a repair shop or Poulan Pro dealer to determine the cause.

Your Poulan Pro Mower’s Ignition Switch Is Broken

If you insert the key and turn it but nothing happens, the problem may lie with the ignition key switch. You will be unable to get your Poulan Pro to turn over and start.

If the ignition switch is suspect, try testing its continuity using a multimeter. Find the prongs labeled B for the battery and S for the starter solenoid to accomplish this.

Place the key in the lock and turn it until you reach the “start” position. With the multimeter’s resistance setting engaged, connect one probe to the B prong and the other to the S prong.

Good resistance readings for the key switch to the ignition should hover around 0 ohms. If the resistance reading on your car’s ignition key switch is infinity, you need to replace it.

A Faulty Poulan Pro Safety Switch

To ensure your safety, a technology to detect the presence of a human operator has been built into your Poulan Pro. Failure to start can be caused by a faulty safety switch, such as the brake switch or seat switch.

Use a multimeter to make sure your switch works. To troubleshoot, you can also temporarily disable the safety switch to see if the switch is faulty.

Never cut grass without first flipping the mower’s safety switch.

Bypassing a safety switch on a lawn mower is dangerous. One should always have a safety switch handy since you never know when you might need it to prevent a catastrophic accident.

Your Poulan Pro Lawnmower’s Starting Solenoid Is Broken

Your Poulan Pro mower’s engine relies on the starter solenoid, an electromagnetic switch that, when activated, sends a signal to the starter motor to begin cranking the engine.

When the spring weakens or the copper plate corrodes, the starter solenoid can fail. The solenoid might fail for a variety of reasons, including a weak starter, a dead battery, or an improper ground.

The battery needs to be completely charged before the starter solenoid can be tested. Proceed with the methods to identify a faulty starter solenoid to further test the solenoid.

Poulan Pro Lawn Mower Starter Motor Issues

When you’ve determined that the Poulan Pro’s inability to start is not due to a lack of power from the battery, cables, cabling, ground, or starter solenoid, you can move on to the starter. It is possible to remove the starter and put it through its paces.

Before you go out and buy an expensive new starter for your Poulan Pro lawnmower, I suggest getting your starter tested at your local repair shop that specializes in starter and alternator repairs.
