the metal mount bracket is the ground
The roll of drain wire in the cable is to complete the circuit from the shield to the ground. This allows all the excess electrical noise to be routed to the ground.
The 1993 BMW 325 radio wiring colors are red, brown, green, yellow, and white. The red wire is the positive wire. The brown wire is the ground wire. The green and yellow wires are the speaker wires. The white wire is the auxiliary wire.
The red wire is the positive wire. The black wire is the ground wire. The green and yellow wires are the speaker wires. The white wire is the auxiliary wire.
A bad ground wire is the most common cause of turn signals and brake lights not working. The ground wire connection might be corroded.
It means a wire in the ground.
Routing protocols are used by routers (RIP, EIGRP, OSPF) Routed protocols are the actual protocols on the wire (TCP/IP)
That Thermostat is LOW voltage. IT does not have a ground wire. There is no need for a ground. it only opperates on 24 volts. there may be a green wire but it does not mean it is a ground
If there is no ground wire connect the ground wire to the neutral wire.
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
check your ground wire to the gauge
