If you are running a 24 volt starter with two 12 volt batteries
Battery one negative to ground on the vehicle. positive to negative post on battery two and positive on two to the starter.

### Positive and negative points

Use a multimeter to test the contacts, the red probe on the multimeter is positive. When you place the red and black probes on the battery contacts and the meter reading is negative then the red probe is on the negative contact, if the reading is positive then the red probe is on the battery's positive terminal.

### I need a simple wiring diagram to turn on 40 red leds and 40 green leds on a 9volt battery

Two ways to do it..........

One is a Series circuit, the other is a Parallel circuit.

Of course you can also use a Series/Parallel circuit.

Each LED has a Positive ( + ) connection, and a Negative ( - ) connection.

A) Series circuit:

One side of Switch is connected to Positive ( + ) of the Battery.
The other side goes to the Positive ( + ) of the first LED light.

Then the LED's are connected together in a Series.

Negative of first LED light to Positive of second LED light.
Negative of second LED light to Positive of third LED light.
Negative of third LED light to Positive of Fourth LED light.

And so on, and so on, until you come to No.40 LED light.
It's Negative connects to the Battery.

ONE LED goes bad, and none of them will work.
Old Christmas light strings are set up this way.

B) Parallel Circuit:

Switch to Battery - Positive ( + )
Wire goes from Switch, to 1st LED light's Positive connection ( + )
Then wire from 1st LED positive, to 2nd LED Positive ( + )
Then wire from 2nd LED Positive to 3rd LED Positive.

And so on, and so on, until you reach the 40th LED.

Then wire comes from Negative ( - ) of Battery, to Negative of 1st LED.
Wire from 1st LED to Negative of 2nd LED.
Wire from 2nd LED to Negative of 3rd LED.
Wire from 3rd LED to Negative of 4th LED.

And so on, and so on, until you reach 40th LED.
Wire connects to Negative of 40th LED. Then a wire connects from 40th LED Negative, and goes to Negative of Battery.

Series Circuit;

http://en.wikipedia.org/wiki/File:Series_circuit.svg

Over to the Left side you see the Battery symbol. There is no switch in this circuit.

In the Battery symbol, the Longer line represents the Positive pole.
(Positive connection)

Resistors are represented by the squiggly lines. In place of them put your LED lights.

A Switch would go in-between the Battery, and first LED light; on the Positive side.
(ALWAYS put the Switch on the Positive side. Can explain in detail if you need)

[The Top line in the diagram, is the Positive 'wire' ]

Parallel Circuit:

In a Parallel circuit, if one LED light goes out, the rest stay on.

### In my Motorola t6320 Talkabout, some of the battery connectors have corroded and broken off. Can the be replaced?

The battery contacts are the part you are describing as missing or corrosion damaged. These parts are not available from Motorola for replacement in this radio. Your best solution is to replace the radio. Sorry.

Best regards.

### I want to put 4 batteries together 4x 12v 7AH. and how many volts and AH would that be.

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)

### I need to reattach two deep cycle batteries to my fleetwood rv. Do I attach to one battery ms then attach the extra leads to the other battery , or do I attach the positive lead to one battery and the...

It should be positive to positive, negative to negative - parallel, not serial.

The simple way to tell is by how many cables you have. If you've got one positive and one negative, and only one jumper, it's a 24 volt system and should be connected in serial. If you've got one positive and one negative and two jumpers, it's a 12 volt system, and should be connected parallel.

If in doubt, connect up in parallel and test things. If everything works, it's a 12 volt system and you're good to go. If everything doesn't work (lights are dim, inverter doesn't give AC, etc.), it's a 24 volt system and you need to change to serial.

Serial - positive to system connection on battery 1, negative on battery 1 to positive on battery 2, negative on battery 2 to system negative.

Parallel - positive on battery 1 connects to positive on battery 2 and the system positive, negative on battery 1 connects to negative on battery 2 and the system negative.

### This unit comes with a Four Conductor Cable to hook up power in. How are these four conductors hooked to power?

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.
