scubadave Posted October 7, 2019 Report Share Posted October 7, 2019 (edited) 99 Volvo VNL610 with Cummins N14. Drove about 150 miles this morning and all of a sudden the alarm sounds, no red triangle and no red lights on the air pressure gauges. Pressure reading on both gauges about 105 psi. Alarm sounded for a couple minutes then stopped, air pressure increase towards the end of the alarm. Again about 15 minutes later the alarm came on again but lasted for less than 5 seconds, this time pressure reading about 115. Thus happened a total of about 5 times then nothing further. Drove an additional 30 miles until stopping and everything OK. Any idea what may be causing this?

rpsinc Posted October 7, 2019 Report Share Posted October 7, 2019 Might it correspond with the pressure relief valve? Quote Marcel Link to comment Share on other sites More sharing options...

chief916 Posted October 8, 2019 Report Share Posted October 8, 2019 My rig did the same thing 2 weeks ago. It's a 1997 Volvo WIA 64. Had my mechanic check it out....he changed out my pressure relief valve. Left the next day from Snow Hill NC.......im now in Fresno CA. Everything works fine. The pressure relief valve was 300 bucks and 91 bucks for install. Quote Link to comment Share on other sites More sharing options...

Darryl&Rita Posted October 9, 2019 Report Share Posted October 9, 2019 Please explain the governor comments. The gauges were showing above 100 psi, and the alarm shouldn't come on until the system pressure falls to roughly 60 psi. This sounds more like a pressure switch/sensor or wiring issue than a governor issue.

scubadave Posted October 13, 2019 Author Report Share Posted October 13, 2019 After about 1300 miles after a new governor the alarm sounded twice for about 2 seconds. Today the compressor would cycle about every 9 minutes, much better than the 2 minutes before the governor change. Since the mechanic mentioned a filter in the air dryer, is their such a thing and if so, where might it be located on a 99 VNL610?

Jack Mayer Posted October 14, 2019 Report Share Posted October 14, 2019 I would doubt that the desiccant cartridge would be the culprit. But if you have not changed it you should.

Dave You've got a leak somewhere, if your compressor is cycling that fast. The vent on the dryer may be an issue, but there's a leak somewhere. And, you've still got an issue wwith the alarm.

scubadave Posted October 14, 2019 Author Report Share Posted October 14, 2019 Where might I find the sensor for the alarm on the truck and any Idea it may look like?

Darryl&Rita Posted October 14, 2019 Report Share Posted October 14, 2019 Scroll down on the Heavy Hauler Resource Guide to find the wiring diagrams specific to your truck. Some of them are integrated to the gauges, others have dedicated switches under the dash. There will be more than one sensor, one for the primary tank, and one for the secondary. They both trigger the same alarm, so you need to check both systems.

podwerkz Posted October 22, 2019 Report Share Posted October 22, 2019 Does that alarm sound just like your door-ajar warning? If so, you may have a fault in one of the door switches. Quote Nothing to see here. Link to comment Share on other sites More sharing options...
