I recently replaced the head on my Cub Cadet Original. Keep in mind the tractor was sitting for a while before then, with the battery still in it. I cranked the engine and it slowly turned the engine. I assumed that the battery was dead. After this, I foolishly charged the battery outside where it was cold. So it was hard for the battery to get a charge. This was in December of 2020. With all this snow we got up here on the east coast, I decided to put the cub and a few other projects away to protect them from the snow. Fast forward to now I charged the battery once again, this time inside where it is warm. I put the battery in the cub, pressed the starter button and nothing. Not a budge. I tested the battery with my multimeter and it had a full charge. I took off the belt and spun the pulley on the generator with my hand and it spun just fine. Anyone else have this problem and know the solution?
