In order to test a lawn mower starter with jumper cables, there are a few steps that need to be followed carefully. Here is a step-by-step guide to help you test the starter of your lawn mower using jumper cables:

Step 1: Preparation

Firstly, make sure that the lawn mower is turned off and that it is in a safe and secure location. You will also need to have a pair of jumper cables on hand, as well as a 12-volt battery or a power source that is capable of producing a similar voltage.

Step 2: Locate the starter

Next, locate the starter on your lawn mower. Normally, it can be found near the engine or underneath the engine cover. Once you have located the starter, disconnect the battery using the appropriate tools to prevent any accidents or damage.

Step 3: Connect the jumper cables

Now, connect one end of the red (+) jumper cable to the positive terminal of the battery and the other end to the positive terminal on the starter motor. Then, connect the black (-) jumper cable to the negative terminal of the battery and the other end to a metal surface on the engine, away from the starter motor.

Step 4: Turn on the power source

Switch on the power source, either the 12-volt battery or a source with similar voltage. This will allow the starter to receive the current it needs to turn on.

Step 5: Observe the starter motor

Watch the starter motor carefully to see if it engages and turns over the engine. If you hear a clicking noise or see the motor turn sluggishly, it could be an indication that there is a problem with the starter or that the battery is low or weak.

Step 6: Disconnect the jumper cables

Once you have finished testing the starter, switch off the power source and disconnect the jumper cables, starting with the black (-) cable first, then the red (+) cable. Always take care when disconnecting electrical components to prevent sparks or injuries.


Testing your lawn mower starter with jumper cables is a fairly easy and straightforward process, but always remember to take care when working with electrical components. If you are unsure about your ability to test the starter, it is best to seek professional advice or assistance. Finally, if you find that the starter is not working correctly, it may be time to replace it or seek the help of a professional mechanic.
