Melting fuses

Posted by Paul (QC) on December 02, 2002 at 16:17:52 from (207.253.209.246):

A few weeks ago I was using my loader with its lights for the
first time and at one point they went out. Found the 20a fuse
and it was all melted, half the connector with it. The fusible
link part of the fuse was like new.

Replaced the fuse and a couple of days ago, with the lights on
in daylight to see if all was well, the 30a main fuse goes.
It was all melted too, so much so that half a tab remained in the
hole when I extracted the fuse. Again, the useful part of the
fuse was untouched.

These are the automotive colour-coded plastic fuses with
a couple of spade connectors sticking out the bottom.

The light circuit looks pretty sound though the switch is a
replacement, and the problem I thought at first.

The only reason I can come up with to explain things is that,
from the machine having sat outside, there was corrosion in
the connector between the two parts to the point where the
heat generated by the resistance was enough to melt fuse and
holder (and the link part of the fuse wouldn't be involved).
Is this possible ?

If you've had a machine sit outside a while you might want
to replace your fuses.
