Ran fine then wouldn't start. I jumped it and it was fine for an hour then next day turn key and just a clicking noise and drains battery. We replaced battery fired right up. Then next day nothing but clicking when turning key. Now it wont even take a jump.
Any help thanks in advance.

Hi,

This sounds like you have what is called a parasitic draw. This means something is staying on when it is supposed to be off and it drains the battery. It would need to be something with a large load in order to drain a new battery overnight.

Here is a guide that will walk you through the basic items:

If this does not find the issue then we will need to do what is called an ignition off draw test. If you are not familiar with this, here is a video that explains how to do this test:
