A common issue of Kohler CV742 is the engine cranks but won’t start or the engine bogs down repeatedly. This could happen for several causes. However, in CV742, it is commonly due to the intermittent ignition coil. Don’t worry! You can diagnose and fix it easily.

- Make sure all connections are clean, tight, and free of corrosion.
2. Engine Will Not Crank
Then, if you are unlucky enough, your engine may not crank at all. Several causes may lie behind this issue. Such as discharged battery due to or faulty electric starter or solenoid.
If the battery is not charging correctly, it can become drained and fail to start the engine. Here’s how to check the charging system in a Kohler CV742.
Solution:
To fix a dead battery-
- Charge the battery: If the battery is not completely dead, you can try charging it with a battery charger.
- Jump-start the engine: If the battery is completely dead, you can jump-start the engine using jumper cables and another vehicle with a charged battery.
Connect the positive (+) and negative (-) cables to the respective battery terminals of both vehicles and start the engine of the other vehicle. Let it run for a few minutes and then try to start your engine.
- Replace the battery: If the battery is old or damaged, it may need to be replaced. Check the battery voltage with a voltmeter to determine if it is holding a charge. If the voltage is low or the battery is damaged, it should be replaced.
- Check the alternator: If the battery is not charging even after replacing it, the alternator may not be functioning correctly. Check the alternator output with a voltmeter and replace it if necessary.
