Oh it doesn't run continuously, I may have said that wrong.
Although it is supposed to be connected to accessory power, I have had it running always hot through the vacuum sensor. In theory this shouldn't be a problem as long as the system is holding vacuum, and it has. I replaced all the vacuum lines and check valves just as a matter of course.
The only issue I am having is the relay, that I have to knock on to make it work when it needs to.
This may be remedied when it has a solid mount and the vibrations could make it actuate as it should, but I am looking to just use a better relay that functions properly.
I did replace and upgrade chassis to engine, battery to chassis and battery to block. Under dash grounds will be next and I completely anticipate that remedying my remaining issues.
I'm not sure, what is it that you refer to as "core support"?
As always, I greatly appreciate your input and insight.
