Hi Art,
I got what you are saying about those that like kiss information.
As far as David Samuels a.k.a. Wagonmeister doing a kit that might it be a long ways out.
He could be running out of Volvos that he cares to refurbish.
His fixes, for said, thirty plus year old cars are probably fading as well.
I haven’t seen him on the BRICKBOARD in ages.
A voltage meter would read out how cold the engine is in the morning.
I like your term “Distant Early Warning.”
This type gauge would not just sit in the same ole place for what seems like an eternity.
It could give the owners more knowledge on how long they can still use a cell phone or multitasking with the kids. 😵💫
So no need for an outside temperature reading from a door hinge area or under a bumper.
Ford use to recommend warmups of 30 seconds to allow for oil delivery and piston skirt expansion.
On motorcycles I was taught to warm up an engine until you could feel some heat coming from a cylinder’s barrel fins with your fingers.
Boy, that was back in the late sixties! Definitely a KISS method.
A .34 reading volt would be a normal operating temperature zone.
More towards zero volts would be the red zone.
A ECU voltage meter could tell you how much more the crankcase heater needs to be on.
Luckily, I have never used one of those.
I don’t know if they have thermostats? Do they?
Do they even heat the coolant?
Jeez, I Never had to ponder this before.
Living back East in the snow belt and owning a car must be a bear?
I would bet the white coat LAB boys, in fuel management, had some accurate meters.
I used thermometers filled with Mercury.
I still have a pimento jar, about one-fourth full of Mercury.
I salvaged it from high current relays and switches.
Probably an ecological no-no today and rare to buy anymore.
I have a few Volvo trunk lights. I have one of those left plus other vials with wires hanging out for experimenting. Pack rat? I could be?
Hey Art … are we or am I stealing the thread a little?
Nice chat and Have a nice evening. 🤐
Phil
