If you are talking about disconnecting a battery in a vehicle, yes.
You have to disconnect the ground wire from the block. You have to disconnect the positive wire from the starter and the alternator and the powerline going to the fuse box. and connect the new ground then the positive
Answer for USA, Canada and countries running a 60 Hertz supply service.Underground or using triplex, a new ground has to be established at the new distribution's sub panel. It must be in the form of a ground plate or ground rods with the ground wire being connected to the neutral point in the sub panel.
You don't want to remove the ground wire because it protects the two wires inside from RF frequencies, but in case you have a ground loop problem, you might want to disconnect the ground using a ground lift.
No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the power wire is plugged in..
Disconnect negative (- black)(ground) first. Reconnect last too.
Establish which terminal is connected to ground and disconnect the wire from the terminal. Disconnect the terminal on the other battery that is connected to the load. Finally disconnect the loop between the batteries.
Black wire to gold screw terminal, white wire to silver screw terminal, ground wire to ground terminal. I am sorry, I can't even begin to answer this question. I don't what you are trying to do and I am positive you don't either. Call a pro, please...pkazsr
disconnect the negative (black) first then positive (red).
Disconnect the plug to your fan. Hook a jumper wire to ground the negative wire and a hot wire to the positive wire. If the fan doesn't work, then you can buy one on Ebay or other sources.
on cooling fans disconnect wire at fans,runwire from fan side to positive on battery!!run another wire to ground. if they are ok they will run!!if not it can be bad fans or a bad fan sensor!!check for bad fuse!!first
Get your new sparkplug wire kit from the parts store then disconnect the battery ground cable. Pull the coil wire off of the center connection. If you have a coil pack disconnect one wire from the coil and disconnect the other end from the spark plug. Find the new wire that matches the one you pulled and put it in place. Do one wire at a time so you don't mix up the timing. Did you check your rotor and cap? Did you check your spark plugs? Did you test your coil?
# Disconnect negative battery cable (8mm) # Follow first wire and disconnect at alternator bracket (15mm) # Follow second wire and disconnect at radiator support (13mm) # Installation is reverse of removal
