How to Test for a Faulty Boat Starter

Are you finding it challenging to rev up your boat? For marine engines, the boat starter in Winter Garden, FL, can be a finicky device. Today, we will discuss what you can do to determine whether your starter requires replacement. Please note that these instructions are for a 12V operating system.

First, let us rule out the other possibilities that can cause an engine to refuse to start. Be sure you are following the manufacturer’s directions for starting your boat. Also, ensure the main fuse is still in good shape and be sure all electrical connections are clean and connected correctly.

With these issues are taken care of, it is time to get your multimeter. Follow these steps:

  1. Turn the dial of the multimeter to DC voltage. Place the red probe and the black probe on their respective posts (red is for positive, black for negative). If the reading is below 11.3, replace or recharge the battery.
  2. With the multimeter still on the DC setting, place the red probe on the engine starter’s positive terminal and the black probe on the engine ground.
  3. Turn your ignition switch to “Start” and read the voltage. If the reading is more significant than 9.5 volts, try to start the engine. If this test fails, then your boat starter requires replacement or rebuilding. If the reading is less than 9.5 volts, you have a voltage loss between the battery and starter. Address this issue and then attempt the test again.

With the right equipment, you can determine whether your boat starter in Winter Garden, FL, requires service. Visit us for a replacement today.
