How to Test Outboard Condensers

The condenser on an outboard motor is an electrical device that is part of the ignition system that stores a high voltage charge, similar to the way a capacitor does. Each end of the condenser is a contact that releases the charge which in turn, sends fire to the spark plug. If the condenser is out it can cause the outboard to stop running. The condenser is tested with an analog volt meter.

Instructions

    • 1

      Unclasp the latches and remove the engine cover and set aside.

    • 2

      Remove the outboard coil retaining screws, near the plugs, with a Phillips screwdriver.

    • 3

      Remove the retaining screw for the condenser and pull the condenser out.

    • 4

      Set the multimeter to the Ohms position and place the positive meter lead to the positive terminal of the condenser and the negative meter lead to the negative condenser lead. The meter needle should jump to the right.

    • 5

      Reverse the leads with the different condenser terminals. The meter should jump to the right again. If the meter does not register a reading in either direction it means the condenser is bad and needs to be replaced.
