usrjcro11 Posted February 1, 2022 Share Posted February 1, 2022 Just bot a 1994 CH613 with a 350 to go with 1991 CH613 with a 300. Both of these trucks are used on farm. Question is can you ground some of the sensors like the differential to test the wires to gauge and also the gauge. How is proper way of testing any sensor without damaging anything. Not worried about oil or temp. Thanks in advance Quote Link to comment https://www.bigmacktrucks.com/topic/69134-sensor-wire-treating-and-gauge-testing/ Share on other sites More sharing options...
theakerstwo Posted February 1, 2022 Share Posted February 1, 2022 The rear end and trans sensors can be grounded at the sensor and gauge should read full.But for the engine sensors stay away from them as for as shorting them cause you can do damage to your pocket book.If you want to short circuit the rear end and trans gauge then use a test light and one of them will make the gauge read full. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/69134-sensor-wire-treating-and-gauge-testing/#findComment-488274 Share on other sites More sharing options...
Joey Mack Posted February 1, 2022 Share Posted February 1, 2022 so to test the sensors, if you have the chart with the ohms readings, you can test them with a DVOM.. another thing you can do is... pull the temp sensor out, get a friend to watch the gauge, and hold a lit bic lighter on the brass end and have youre friend tell you if the temp gauge rises....jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69134-sensor-wire-treating-and-gauge-testing/#findComment-488275 Share on other sites More sharing options...
usrjcro11 Posted February 2, 2022 Author Share Posted February 2, 2022 Thanks all. Will do rearend and trans sensors Big thanks to all Quote Link to comment https://www.bigmacktrucks.com/topic/69134-sensor-wire-treating-and-gauge-testing/#findComment-488306 Share on other sites More sharing options...
Joey Mack Posted February 2, 2022 Share Posted February 2, 2022 (edited) have some 1/2" pipe plugs handy if you do pull the sensors. you will need to 'hot swap' the plug into the sensor hole.. jojo Edited February 2, 2022 by Joey Mack Poor spelling Quote Link to comment https://www.bigmacktrucks.com/topic/69134-sensor-wire-treating-and-gauge-testing/#findComment-488308 Share on other sites More sharing options...
