NO you cannot.
. Artical 240.40of the NEC2008 code states Disconnecting Means for fuses. Cartridge fuses in circuits of any voltage where accessible to other than qualified persons, and all fuses in circuits over 150 volts to ground, shall be provided iwth a disconnectiongs means on their supply side so that each circuit containing fuses can be independently disconnected from the source of power.The top is marked line. This is where you connect the incoming power source. Then the switch then the fuses then the outgoing or load connections. thats why there is enough space in the disconnect to allow the wires to loop in from the bottom of the disconnect to the top line side lugs.

Have a delcotron alternator ,what to know where no.1 terminal and no.2terminal wire goes it is on my 1946 cj2a jeep my amp hand does not show a charge had alternator checked out and is ok

  • Use a wrench to remove the negative and positive battery cables: They are clearly labeled "+" and "-." Always remove the negative cable first, as this isolates the power to the metal parts of your car. Tuck the cables away from the battery as you don't want them to accidentally touch a battery terminal when you're wiring your alternator.

  • 3

    Locate the alternator terminals. There are two: one marked "live," "pos" or "+" and the other marked "neg," "field" or "-."

  • 4

    Locate the two cables. The positive (red) cable goes to your battery via a wire loom or harness. The negative (black) cable attaches to a metal part of your car.

  • 5

    Check how the cables attach to the alternator terminals. Some connect using eyelets that hook over the terminal and tighten with a bolt; others connect by inserting the wire under the terminal and tightening a bolt.

  • 6

    Loosen the two bolts using a suitable-sized wrench or, if the cables connect using eyelets, remove the bolts.

  • 7

    Insert the exposed end of the negative (black) cable under the loosened bolt on the negative terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

  • 8

    Insert the exposed end of the positive (red) cable under the loosened bolt on the positive terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

    Replace the positive battery cable on the positive battery terminal using a wrench. Replace the negative battery cable on the negative battery terminal.

    I have a powerware 9120 and had to replace batteries, unfortunately I had a blonde moment and didnt take note of how the 3 batteries were connected, so my question is are they all connected together with...

    Batteries are connected in series on your PW9120-1000. Connect the battery farthest from the end that faces the front display of the UPS with the incoming red wire to the red terminal on that battery. Connect the short cable from the black terminal on on that battery to the red terminal on the next battery (these batteries will face each other, but one set of terminals will be at the top and the other set will be at the bottom). Connect the longer wire from the black terminal of the second battery to the red terminal of the last battery (which will face opposite the 2nd battery). The black terminal on the last battery will connect to the thick black wiring coming in from the rear of the battery case.

    Disconnect the battery. Connect the green wire to the Negative terminal.Put a 20a fuse inline on the black wire and connect to Negative terminal.Put a 20a fuse inline on the red wire and connect to Positive terminal.
    Put a 1a fuse on the yellow wire and connect to ignition switch - if you don't want to use the Ignition Sense feature, connect the yellow wire to Positive terminal.Re-connect the battery and test.

    It will be a hazard to some else who opens it someday thinking the hot wires are at the top. Best answer is to check you counties electrical code. My answer is no I wouldn't hook incoming wires to bottom lugs.

    What is the negative battery cable bolted to and do I have to remove the battery to replace the cable?

    The negative terminal on the battery is the one with the minus, usually the positive is red.
    Disconnect the negative cable from the battery for safety. Then follow the cable to where it attaches to either the engine block or the body. They unbolt it and replace it.
    You shouldn't have to remove the battery for this. Just don't mess with the positive terminal. You will have to reset the radio stations etc since battery is disconnected.
    If the connection at the negative side is corroded, just cut it and reconnect it with a new battery terminal. A parts store can hook you up with that.

    Dead battery on a 2006 Volkswagen Jetta. How do I jump the battery?

    under the hood, you will see a positive battery connection, and there should be a bare metal area on the engine you can use for ground. Clip the BLACK clip of one side of the jumper to the negative terminal of exposed metal on the jetta, then hook the other black clip to the negative terminal on the battery of the other car. Start the other car. Now, hook the RED clip on the jetta side of the cables to the postitve terminal on the jetta, then go and hook the other red clip to the positive terminal on the running car. Let the running vehicle run for about 3-5 minutes, and then with the cables STILL connected, start the Jetta.

    After this is done, remove the jumper cables, one clip at a time, while being careful to NOT let them (the clips) touch until they are disconnected from BOTH vehicles!

    Hope this is the info you needed!

    Battery issue.....

    look closely if there are wires hanging near the positive terminal of the battery.

    you could have miss reconnecting one wire that is connected to your starter or the main cable itself is corroded and is not making a contact. that main cable is the one hooked to the starter.
