....which suggests to me that they're far from fine for the job
considering where they are! :D
We've had three switches (I think) fail and one connector so the next
switch will have wires soldered in to it.
I'll probably seal the joint with sleeves and heatshrink. and put a
connector somewhere along the wire.
Or I might look at using something like a Kenlow fan switch, anyone
tried that with the standard fan?
Meanwhile, I'm glad I wired in an overide switch last year- no relay,
just very thick wires and a meaty switch- less to go wrong!
Steve, I've had a fair bit of bother with relays, it's all down to
poor connections in the fusebox-
had to relocate the headlight relay because the contacts had got hot
and melted the plastic!
I've got a fresh fusebox, now I just need the tool for removing the
contacts....and a lot of patience!
