Larry - I had an electrical problem when I first
bought my elco (used). After we "fixed" it, we
reconnected the batteries, only to melt down a number of
wires before we could get the fuses disconnected. They
were so hot to touch we burned our hands. I asked why
the fuses didn't blow and was told that they were
designed to function slowly. In this event, so slowly that
we melted a bunch of wires. I still do not know if
the fuses would have ever blown. Paul Preuss
