Bill w/bus Posted October 1, 2020 Report Share Posted October 1, 2020 Found out the expensive way that engine and transmission sensors don't respond well to a VOM to check for continuity. Most VOM's operate on a 9VDC battery. Sensors, at least on Detroit engines and Allison transmissions, require 5 VDC. Found the very fine print in the transmission troubleshooting manual. After we found the cause for the DNS code, Do Not Shift, which was oil level sensor failure. Temperature sensor is on the same circuit and had failed open. So the resistance check probably wiped out the level sensor. Anyway I haven't had any leads to such a power supply. Any thoughts or leads would be appreciated.
