Hi Mark,
Thanks for this. I’ll need a little help for this one so will try when a friend is available and hold on ordering other parts in case this is the trouble area.
Things may look different down there as Dennis upgraded some wires but the original fridge relay I think is still there. I’ll take a look to familiarize myself with the wires.
I really need an audio multi meeter and a tech lesson!
