A Complete Guideline On Bench Test Of A Lawn Mower Starter

Before replacing the starter, you must make sure that the current lawnmower starter is totally damaged. You can be sure of this by testing some parts and connections. 

Now, let’s have a look at what parts and connections you have to test before the bench test of the starter.

The mower battery needs to be checked before checking for any problems with the starter. This is because the power is supplied from the battery to the starter to turn on the mower.

If the battery is not charged properly, it will not be able to supply enough power to the starter. You know most of the lawnmowers use 12 volts batteries. And you can check the battery by using a multimeter.

If the battery shows 12 volts in the multimeter, the battery is in good condition. But when the battery shows less than 12 volts, it indicates the condition of the battery is slowly deteriorating. And the battery needs to be replaced as soon as possible.

  1. Check all electrical connections

If all the electrical connections in the lawnmower are not connected properly, then the mower will not turn on. When the connections are broken or loose, it will not be able to supply power to the starter.

  1. Inspect the solenoid

Starter solenoids play an important role in starting lawn mowers. When the key to the lawnmower is rotated in the keyhole, electricity from the battery is transported to the solenoid. The solenoid then supplies power to the starter motor to turn on the mower. 

If the solenoid is faulty, you can not start the lawnmower. And when you attempt to start the mower, it only sounds click but the lawnmower will not be turned on.
