Hi I tried to search but didnt see this one so hopefully I'm not going over something some one else read ask. I have a 89 Cummins and getrag Tranny I've installed into a Humvee. The gauges in the Humvee are 24volt. The engine is 12 volt set up. I'm running a 12 volt system completely. But I want to keep the gauges as they look nicer. So I thought of getting one of those 12 to 24v converters but questions: can I run the 24v through the sensors (oil and temp) and if they ground through the engine block is that gonna mess everything up (grounding 24v info 12v system)? Thank you! Or is there a way to convert the 24volt gauges to 12 v internally?
