Oil Temperature Gauge: Testing and Inspection
Check for a defective wire inside the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with the
system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop
with the system operational.
