E300 hello i have four batteries two are connected i would like to know how i connect other two like + to + or + to negative or do i use a separate switch,and if i can recharge them two at a time,Do i use two switches or just the one when recharging batteries

Hi, you would connect the positive side of one battery to the negative side of the next battery. Then connect the positive side of that battery to the negative side of the next battery. Do that two more times until all four batteries are connected-positive of one battery to negative of next battery. The last battery will have 48 volts as compared to the negative terminal of the first battery. I can make a picture if you need it.

The positives are separated by the selector switch.
Therefore negatives (or negative earths) can be commoned and left connected to batteries.
As a circuit needs to complete a closed loop from battery positive through the selected switch contact through the load 'caravan' then back to negative, the unselected negatives don't do anything.
So, YES WE CAN. :)
Hope this helps.
Clive.

You haven't given me much information, Wendy, such as why you want to test them, or if they are in the scooter. I'll presume that they are not connected, and that you think there may be a fault in the scooter. To test them you will need a multimeter, and if you own ones of these you would know how to test the batteries. They are too expensive to buy for a one-off job, and I won't confuse you by telling you hoe to set up a test lamp.......Hook up the batteries to the scooter and see if it works....Don't forget that the red wire goes to the POSITIVE ( or Plus ) terminal, and the black wire goes to the NEGATIVE ( or Minus) terminal. If you are still having trouble, take the battery to a battery supplier and ask him to check it for you. Please don't forget to rate this answer.

It depends on how you connect the batteries. If you connect the negative of battery one to the positive of battery 2, the negative of battery 2 to the positive of battery 3 the negative of battery 3 to the positive of battery 4 then the positive of battery 1 and the negative of battery 4 will give you 48v 7AH. (This is known as connecting in series.)

If you connect the four positives together. Connect the 4 negatives together it will give you 12v 28 AH. (This is known as parallel connection.)

If you connect the negative of battery 1 to the positive of battery 2. Connect the negative of battery 3 to the positive of battery 4. Connect the positive of battery 1 to the positive of battery 3 and the negative of battery 2 to the negative of battery 4. You'll get 24v 14AH from the connection of the positive of battery 1 and battery 3, and the negative of battery 2 to battery 4. (This is known as series parallel connection)

Wiper Motor

Removal & Installation

1. Disconnect the negative battery cable.
2. Disconnect the wiper motor electrical connector.
3. Remove the four mounting bolts securing the motor to the firewall.
4. Using a suitable prybar, carefully separate the wiper motor from the wiper linkage and remove the motor.

To install:

1. Attach the wiper motor ball joint to the wiper linkage.
2. Position the motor on the firewall and secure the motor with the four mounting bolts. Tighten the mounting bolts to 75 ft. lbs. (102 Nm).
3. Connect the electrical connector.
4. Connect the negative battery cable.

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.

Check this procedure for models without A/C...

1984 AND LATER

1. Disconnect the negative battery cable, heater blower resistor wires and blower wires. Disconnect the heater core ground strap at the dash panel.
2. Drain the cooling system and then disconnect both heater hoses at the heater.
3. Remove the seven screws attaching the heater/blower case to the plenum and remove the heater/blower base.
4. Remove the four screws from the heater core shroud, and then remove the shroud and core assembly.
5. Separate the core from the shroud by removing the three screws and core mounting clamps and then separating the two.
   

To install:

1. Using sealer as necessary to prevent leaks at all joints and flanges.
2. Position the assembly onto the dash and tighten the retaining screws.
3. Reconnect the heater hoses, electrical connectors and negative battery cable. Refill the engine with coolant, start the vehicle and check for coolant leaks.

And this procedure for all Buick models with A/C...
1977 AND LATER

1. Disconnect the negative battery cable and drain the cooling system.
2. Disconnect the heater hoses.
3. Remove the retaining bracket and the ground strap. Disconnect the module rubber seal and module screen.
4. Remove the right windshield wiper arm.
5. Remove the diaphragm connections, the hi/blower relay, the thermal switch mounting screws, and all the electrical connections from the module top.
6. Remove the module top cover and remove the core.

To install:

1. Apply a strip of caulk-type sealer when installing the module top.
2. Install the core and module top cover.
3. Install the diaphragm connections, the hi/blower relay, the thermal switch mounting screws, and all the electrical connections to the module top.
4. Install the right windshield wiper arm.
5. Install the retaining bracket and the ground strap. Connect the module rubber seal and module screen.
6. Connect the heater hoses.
7. Connect the negative battery cable and refill the cooling system.
8. Start the engine and check for coolant and vacuum leaks.

Hope helps (remember rated this).

bi-wiring requires the removal of the copper jumpers between the hi and low speaker terminals. you can use two wire pairs twisted together at amp out connections and the four separate ends at each speaker, but the quality of sound will not be as good as buying quality bi-wire cables. But a pair of quality single set of wires at each speaker would be fine, but put jumpers back on and attach to the top terminals, they are designed that way. bi-wiring does allow the crossover to put out a little better sound. Hooking up four sets of wires to the a and b speaker terminals sounds bad. i have had alot of trouble with my rti10's and learned the hard way that it is best to pay more for wires with quality terminations.

if it is 24v. then you need to connect 2 battery in parallel. since the battery is only 12v.
if one battery is shoing red and the other is sohwing green, that means you are using 12v only, not the 24v.
connetion as follow:
positve of battery 1 to the motor, the negative of battery 1 to postive of battery 2. the negative of battery 2 to the motor.
