Thumbs up wont start after i flushed the coolant system and replaced the thermostat

i flushed the coolant system and replaced the thermostat and it ran fine for a day or two then one morning it wouldnt start. i jumped it itstarted fine it worked all day wouldnt start again next morning. after lookin at it it figured its either the battery or the negative ground cable. the battery has 12volts but when i try to start it it drops to 9 or 10 volts... any suggestions? ima replace the ground clean the terminals if it still has the same issue replace battery i would appreciate any other thoughts b4 i start spending monies.

Does the engine cranks?? If it doesn't crank, then the problem is probably the starter motor.

It started when you jump it so I would say its the battery. When battery goes down to 9 and below its time to replace.

I concur. The battery is probably dead.

If you jumped the vehicle and started the starter was bypassed and compression and battery power is what started the vehicle. Therefore I would check the wire between the solenoid and starter body for breakage also check the main battery wire on starter for being burnt. If battery is also a suspect have it checked.
