The weather was just above freezing so I was able to haul some stock piled clay. Truck started good and the switch I installed for the solenoid valve on the hoist works perfect. The problems I had today were the daytime running lights got dim and eventually went completely out. It was getting dark so was easy to notice. I was also losing air faster than normal. I think the air problem could be cold weather related. The air dryer is a a finned type that I believe is supposed automatically purge itself. The one needle on the air gauge would drop a lot faster than the other one so I think something is maybe sticking. After running for awhile both needles come up to just under 120 PSI so I don't think it's a major issue. It was more of problem trying to drive and put the brakes on to get the sticky clay to dump. Then I had to wait for the pressure to build back up. Also the buzzer was half as loud as normal and didn't shut off until 70 PSI. Is this something to worry about? I don't use the truck much in winter and it's just on my own property. The truck is a 1994 L9000 with a Cummins M11.
