How do you tell if a coil is bad on an outboard?

How do you tell if a coil is bad on an outboard?

Bad Coil Symptoms in an Outboard Motor

1. Cracked Body. The coil on your outboard is a sealed unit.
2. Hard Starting. If the coil is weak or damaged it will produce less spark energy than it is designed to.
3. Engine Misfires.
4. No Spark at Spark Plug Gap.

How do you check for ignition coil problems?

Once the engine is cranked, you should look for blue sparks along the spark plug gap. If you can see blue sparks, this proves your ignition coil is working correctly. If you don’t see blue sparks or you see orange sparks, this is a sign that there’s a problem with your ignition coil.

How do you test a small ignition coil with a multimeter?

Testing Procedure Scratch the lead on the plate to ensure it’s in contact. Touch the meter’s black lead to the metal coil housing and watch the meter. If the meter’s display indicates a value of 2.5 to 5 K ohms, then the coil is good.

How do you test a 2 stroke coil?

Attach one end to the boot of the coil and the other end to the plug. Pull the starter rope or kick it off and see if you get any spark. If you don’t see any spark in the window of your tester, it means that the coil needs replacement.

How do you test a marine outboard coil?

How to Test a Marine Outboard Motor Coil

1. Disconnect the wires from the positive and negative terminals on the coil. These terminals are connected to the primary circuit.
2. Disconnect the spark plug lead from the coil tower.
3. Turn on the volt meter.
4. Test the primary circuit.
5. Test the secondary circuit.

How many ohms Should a coil read?

Most coils should read between 0.4 and 2 ohms. Zero resistance would indicate a shorted coil while a high resistance reading would indicate an open coil.

How many ohms should a 12 volt coil have?

The normal, acceptable range for a standard 12-volt car is 1.5 to 1.7 Ohms.

How many ohms should a ignition coil have?

Connect the positive lead to the positive terminal of the coil. Connect the negative lead to the negative terminal. A typical value would read 0.4 – 2 ohms.
