I changed out the micro switches and the solenoid. I still have about s six second delay before the cart kicks in and actually starts. You can hear a whirring sound during the delay. Any suggestions?

For your particular model, being a Club Car with the Kawasaki engine, it’s often the case that the belt does not have enough tension. Even if the belt looks tight, it might not be under the right amount of tension to engage the starter quickly. When the belt is too loose, it can slip on the pulley, causing a delay before the engine actually starts turning over. This slipping is likely causing the whirring sound you hear during the delay. The sound comes from the starter spinning but not being able to effectively turn the engine because the belt isn't gripping the pulleys firmly enough. This delay means that even though the starter is trying to engage, the engine isn't receiving enough torque to start immediately, which explains the six second lag you're experiencing.
To address this, you should first check the tension of the starter belt. A properly tensioned belt should have just a small amount of give, around 1/2 inch of deflection when you press down on it in the middle of its longest run. If the belt deflects more than this, it’s too loose and needs to be tightened. Here is a similar thread that goes into greater detail.
If you've replaced the belt and confirmed its tight, we can move on to other potential culprits like the battery. Even if the battery seems to have a charge, if it's not delivering enough power consistently, it can cause delays in starting. Batteries can degrade over time, losing their ability to hold a charge, which can lead to performance issues like the one you're describing.
Another possibility is dirty or loose starter connections. The connections between the battery, solenoid, and starter need to be clean and tight. Corrosion or loose connections can impede the flow of electricity, causing delays and making it harder for the starter to engage promptly. It's a good idea to check all your terminals and connections to make sure they are clean and secure.
You might also be dealing with bad starter/generator brushes. The brushes inside the starter/generator wear down over time and can cause a delay in the starting process if they are not making good contact. If the brushes are worn out, they might not be delivering the necessary current to start the motor immediately, which could also explain the whirring sound you hear during the delay.
