BIG SNIP


Or the story an instrument man told me: he was trying to troubleshoot
a large panel with loads of connections in spring terminals. Looking
at wire markers, everything looked in order. As soon as he removed a
wire, though, he found that none of them had been stripped.

I'd have made sure that guy was gone for good.

Hey Peter,

As I said.......

Jeeezzzzuuusss.!!!!!!!

We had a lot of units that used maybe 100 to 150 AC relays on the
panel and wires all with AMP manufactured solderless connectors
crimped on from the factory, mostly fork type. Most are sorta "pilot
duty" and don't carry much current. After 10 or 15 years, the wires
break JUUUUSSSSTTT inside the crimp end of the AMPs, but the stranded
wires have become brittle and stay right in place, so we get
intermittent faults. Bitch to find!!

Never had the same trouble with T&B connectors.

Brian.
