Great stuff from all.
Kind of like this one for simplicity's sake.
Don,t know which one of the 3, I would get.
The EG01- 2 has 2 temp. leads that could be so easily hooked up. 1 strapped to the oil filter
with a stainless hose clamp. and one bolted to the elbow
of the heat exchange. Mount the unit down in the galley
Mount the buzzer any where. Maybe 2 buzzers, 1 up top and 1 down below.
Going to research
wether you get 2 diff. temp. readouts from the 2 diff. leads.
