Which is the third stroke of the ignition?
The third stroke is the ignition or combustion stroke (now we’re getting somewhere). At this point the spark plug fires and ignites the air-fuel mixture, causing the piston to be pushed back down to the bottom of the stroke. The final stroke is the exhaust stroke.
Where is the mark on the ignition timing?
With the light wired up per the instructions and the engine running, point the light at the main pulley that comes off the crankshaft. This pulley has a notch or mark on it. On an engine timed to zero degrees advance, also known as Top Dead Center, that mark will appear to flash with the light pointed at it.
Where is the timing mark on a crank pulley?
You can also shut off the engine in this way. On most crank pulleys, there is another mark. This is the mark you aim for, usually somewhere between 3-5 degrees before Top Dead Center. All you do is turn the distributor until that timing mark is flashing at the right spot every time.
What does static ignition on Moss motoring mean?
For most of our older British sports cars, however, “static” timing is specified. This simply means that the timing is set with the engine not running. Before considering checking or setting the ignition timing, it is imperative that the condition of the points and the point gap be checked and reset, if required.
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 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.
What happens if there is no spark in the ignition?
If there is a weak spark or no spark at all, then ignition is not going to happen. Check the spark plugs, ignition circuit, ignition switch, ignition module, and the crank position sensor.
What kind of ignition system do I Need?
If you buy the Mopar Performance electronic ignition system, it comes with extensive instructions, wiring diagrams, and other information. This is for a completely new electronic ignition system, replacing a current one (or a points system), on a Chrysler Corporation vehicle.
