Anyone else having problems with corrosion in their main fuse holder? We had 16 pounds last week, but almost had to quit because we lost all power about 9pm. The fuse itself was demolished. Cracked plastic and corroded metal had to be removed with pliers. Inserted new fuse, but connection was intermittent. I cleaned the fuse holder when I got home and adjusted the contacts for a tighter fit. So far it works, but where is this problem coming from? The batteries show no sign of leaking and I leave the rear compartment lid open when in the garage, so I don't think battery acid is the culprit. This is the second time I've had this problem this year.
