What would cause a motor not to get spark?

Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.

How do you test an Onan condenser?

How to Test a Condenser in a Small Engine

1. Remove the condenser from the engine.
2. Switch the volt ohmmeter to the ohms position.
3. Touch the red lead to the hot connector on the condenser.
4. Remove the leads and reverse the placement to the condenser.
5. Movement from the meter’s needle indicates the condenser is good.

What should I do if my Onan engine has no spark?

This is a typical ignition coil for an Onan engine. If you are getting no spark at the spark plugs, remove the plug wires and check for continuity. No continuity means a bad wire. Replace both of them. Verify the condenser is not grounded.

How can I test my Onan ignition system?

Connect a test light to chassis ground. Put the other end of the test light on the positive terminal of the coil. Turn the key on. If the test light is not lit, verify you have a good ground. If the light is still off, check for a bad connection between the coil and the key switch.

What do you need to know about an Onan generator?

Before any evaluation of the controls, regulator or generator can proceed, the Onan engine must have oil and fuel, be in running condition and the 12-volt battery charged. The electronic governor, 151-0752, on Models BGM and NHM, Spec B and later, must be functioning properly.

How to know if your engine has no spark?

First Confirm Your Engine Has No Spark. 1 Disable the fuel system by removing the fuel pump fuse or relay. 2 Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. 3 Finally, Have someone crank the engine and watch for spark.
