i have 7.5kw dynmo and 2hp motor the motor attach
with home electicity and dynmo show 225 watt but not working dynmo to motor i dont no tell me plz
to the frame of car
a bad ground wire can ruin an alternator by not completing the circuit
There is no ground wire.... it grounds through where it touches the engine
Refer to your service and user manual on how to change an alternator ground wire on a 1994 Mitsubishi 3000 GT.
Yes, if it shorts to ground internally.
On a dodge alternator the two small wires go to the voltage regulator . It doesn't matter which wire goes where, but the red or blue wire needs 12 volts when the key is on. The green wire goes directly to the regulator from the alternator. The large wire goes to the battery and it is important that you don't undersize this wire. The other wire is a ground wire and can be grounded to the block or not used as the case is grounded by the bolts that hold it on.
That particular wire is usually 10 gauge.

To wire a one-wire alternator on a diesel farm tractor, first ensure the engine is off and the battery is disconnected for safety. Connect the single output terminal of the alternator to the positive terminal of the battery. Ground the alternator’s housing to the tractor’s frame or engine block, as it typically relies on a good ground connection to function properly. Finally, reconnect the battery and start the engine to verify that the alternator is charging correctly.
I assume the wire in question is the smaller blue wire. Yes it travels inside the car to the central electrics (fuse block) then to the instrument cluster. The cluster feed the battery light power and finds a ground through said wire at the alternator. when the alt starts charging, there is power on that wire from the altwhich doesn't let the bulb get ground and the light is out.
Is the alternator a known good one? You could have a bad rectifier in your alternator causing a short to ground when it is installed.
Wiring a one-wire alternator is straightforward: connect the alternator's output terminal directly to the positive battery terminal. The alternator is designed to self-excite, meaning it doesn't require a separate ignition or voltage sensing wire. Ensure the ground is solid, and you may need to connect a wire from the alternator case to the vehicle's chassis for proper grounding. Always check the alternator's specifications and ensure the battery is compatible.
