FYI I finally got round to repairing my blown silver resistor.
In the end, I used a pair of 0.25ohm 100W resistors in series.

Why not 2 X 1ohm in parallel ?

Because if one blew open circuit, it would leave one resistor left in circuit, which may seriously overheat and possibly catch fire. But with two resistors in series, if one blows open circuit, then the other resistor is safe.

I also down-rated the fuse FL4 from 80amp to 50amp.

We will see what happens.

So far it's survived one rain storm.
