The Green Farmer is driven very infrequently, and the current starter is pushing 25yrs and never missed a beat given a strong battery. I replaced the battery with a new one and all I get is a single click when I turn the key. Jumping with an additional running engine makes no difference and jumping from battery cable direct to the motor connection still gets nothing. Even a few loving taps with a hammer got no results. Is it just a simple dead starter? Given the above, what else could it be?

It’s a bone stock L250 with no accessories at all. Any other checks I can do before trying a replacement ?
