You are testing an energized solenoid in a series circuit using a voltmeter and identify the following circuit conditions:
Voltage measured from solenoid positive terminal to chassis ground: 12.6 V-DC
Voltage measured from solenoid negative terminal to chassis ground: 4.0 V-DC
Voltage dropped across solenoid positive to negative terminals: 8.5 volts
Where is the problem in the circuit likely to be found?

Question

The problem is likely on the negative side of the load because there is a voltage of 4.0 V-DC measured from the solenoid's negative terminal to chassis ground, indicating a voltage drop or resistance in the negative circuit path, which should ideally be close to 0 V if the circuit was functioning properly.
