[UK-CONTEST] A3S Traps

[Colin Chidgey]

Its easy to check an A3S trap.
Just read across it with an ohmmeter.
I should be almost a short circuit.
The usual problem is corrosion under the plastic boots.
The trap wire (tinned copper) screwed to the Aluminium
with a stainless steel self tapper ! this creates a sort of battery!
scrape all the white corrosion off, re-do the connection and they all 
work again.
