1430 Ohms r2 end to end

[bizron]

Why?

3 RFCs - Kitchen, Downstairs and upstairs.

Downstairs r2 e2e = 1330 Ohms.
(1 leg of downstairs to 1 leg of kitchen = 650 Ohms And the other 480 Ohms.)

Kitchen r2 e2e =0.78 Ohms

Upstairs r2 e2e = 0.67 Ohms

I have ideas - kitchen rewire picked up something, somewhere in the refit. Old supplementary bonding acting as an electrode.
Any thoughts?
Cheers

Poor joints. Possible damp or oxidation.

Go round and remake all connections in the ring final.
