Just had a new air compressor put on a year ago when Peterbilt did a new long block
it will charge up to 120 and slowly drop to just above the 100 mark
it won’t go back up again until I get below that 100 mark which is where I assume is where the auto fill is set at to kick back on and run it back up to 120’s
so
It basically runs at like 103…
My auto air tire light on my trailer will randomly kick on. As I again assume they are dropping down to this same 193 mark and then when I drop…
