Fuel injectors, fuel filters, lift pumps, injection pumps, fuel lines and more. The ride becomes jerky trying to keep the speeds below 10MPH.Replace or upgrade your 2007.5-2012 6.7 Cummins fuel system parts. This is most noticeable while trying to navigate dirt roads at slow speeds. Off idle the motor jumps 500 RPMS with the slightest touch of the pedal. I have a 2019 Ram Cummins that surges with light throttle pressure. The ECM adjusts fueling to individual cylinders if the imbalance is within pre-defined limits.Ram Year. Shop Talk At engine idle speeds, the ECM measures the instantaneous acceleration of each cylinder as it fires to determine the cylinder's power. The ECM is located on the intake side of the engine between the intake air horn and the front of the engine. Really in a military truck I can understand using 24 v systems. If your gauges are electrical then you need 24 volts or change the gauges. Manual gauges like oil pressure and coolant temp that are manual only use 24v bulbs to light them up and you will need to switch the bulbs and I believe the bulb pigtails to 12 volts. ĭC voltage flows from negative to positive. What ground system does the Humvee use, I have been around 24 volt systems that are positive ground. allot of the gauges or some of the gauges the only difference is the 24v bulbs used to light up the gauge. If the Humvee has a 24volt system, then use a 24 volt alternator or change the 24 volt gauges to 12 volt gauges.
Not once did I fry a alternator or starter doing this. We used welders hooked/jump start the equipment. In the winter allot of the earth moving equipment wouldnt start just on their own batteries. Your starter can work with 12v or 24 volts or even move voltage. Back in the day allot of semi trucks with larger engines, cat 1693 Cummins K model and the Detroit 12v 71 had 24 volt systems because a 24 volts going to the starter, started the engine better or cranked the engine faster.
