I have no idea what my problem could be. I have gone through 4 batteries in about 1.5 years now. I just took the alternator out and had it tested at the shop and it was fine. It wasn't even bouncing around the load came right up immediately on the machine.

I have taken one of the batteries and given it a full charge again and come back about 4-5 days later and dead again.

Any ideas? TIA

 

check for a battery drain. ie a fuse or light could be drawing current while the care is off and causing the battery to die.
Get a test light and hook it up between the negative terminal and the connector and start to pull fuses
I. f and when the test light stops illuminating then you have found where the problem is. Then all you have to do is trace it down to the exact spot.
