that is the main fuse. That's the one that gets corroded and eats up the connector because of a bad connection. Michvalk, the one you referred to is the charge fuse that is between the alternator and the battery. It's a 55A that fits underneath the screws as you mentioned. It's there to protect the battery etc from the alternator if it overcharges.
Yep your right! Sorry if I led him in the wrong direction
