macattack Posted August 30, 2014 Share Posted August 30, 2014 sounds like a solenoid or circuit breaker clicking.seems to happen when i stop the truck and shift from gear to neutral. the truck has an auto trans.when the clicking happens it does not seem to hurt anything. everything still works and no visible signs of trouble. tha sound is coming from under the dash near the circuit breakers and solenoid.thanks Quote Link to comment https://www.bigmacktrucks.com/topic/36878-clicking-sound-under-dash-solenoid-or-breakers/ Share on other sites More sharing options...
Pawel Posted August 30, 2014 Share Posted August 30, 2014 Hello!If it's a circuit breaker, wouldn't you have to reset it manually in order for it to click again? I say it's some relay, would be interesting to know what it does. Good luck with your truck and have a nice dayPaweł Quote Link to comment https://www.bigmacktrucks.com/topic/36878-clicking-sound-under-dash-solenoid-or-breakers/#findComment-257801 Share on other sites More sharing options...
macattack Posted August 30, 2014 Author Share Posted August 30, 2014 hi.not too sure.its on a mr688s truck and the sound seems to be coming from the center near the front close to where the power inverter connections are.took a peak noticed 3 circuit breakers and a large solenoid. the breakers seemed fine and none were tripped. gonna check the connections at the solenoid.thanks Quote Link to comment https://www.bigmacktrucks.com/topic/36878-clicking-sound-under-dash-solenoid-or-breakers/#findComment-257806 Share on other sites More sharing options...
41chevy Posted August 31, 2014 Share Posted August 31, 2014 The automotive circuit breakers are automatic, they have a bi metal strip that causes them to open under the heat generated under a high draw and reset when they cool down. A short or overload will sometimes cause an endless cycle. They do wear down with age. Most all are available by amperage rating in an auto parts store . More than likely the solenoid is just doing it's thing.

turckster Posted September 17, 2014 Share Posted September 17, 2014 More than likely its a relay clicking on/off. If it were a breaker then you would loose an electrical circuit of some sort, possibly get a fault. For a MR it is normal for "clicking" noises coming from under the center section.
