no air Kenworth

[jlcprec]

I can't build air pressure. I replaced the governor, still nothing. Air is coming out the bottom of the air drier, I know the compressor is working. Now what?

you ought to rebuild the purge valve or replace the air dryer

looks like the purge valve is leaking

How do you know the compressor is good?

I figure if air is coming out the dryer the compressor is pumping air
just my thoughts
