You just connect them in Parallel. Two 12 volt batteries connected in parallel will output 12 volts. Two connected in Series will output 24 volts. Just connect the negative terminal on the first battery to the negative on the second battery. Then connect the positive terminal on first battery to the positive on the second battery. Connect the cables to the second battery, positive to positive and negative to negative. Click the link for a diagram.
I have the same problem with a '82 Poweram 150 - It was suggested to me that it could be the engine is improperly connected to the negative terminal on the battery. Take jumper cables and ground one side to the negative terminal, the other clipped to the engine near the distributor. Might do the trick.

Posts where cables go. They are also called the electrode or terminal. The positive terminal is referred to as the Cathode and the negative terminal is called the Anode.
Positive is connected to the positive terminal on the battery and negative is connected to a ground point on the engine away form the battery. Under the Hood, on the passengers side, is a positive terminal with a red plastic cover. Put your ground on a metal part of the engine. No need to pull up the back seat to hook to the battery.
To get 24v from two 12v batteries you just link between ones positive and the others negative then connect your motor to the spare terminals, but your 12v charging system will not charge them (and any 12v equipment connected to them will burn out!) without removing the link.
To charge the battery on a Volvo S60, you can use a battery charger by connecting the positive (red) clamp to the positive terminal of the battery and the negative (black) clamp to a grounding point or the negative terminal. Make sure the charger is set to the appropriate voltage and follow the manufacturer's instructions. Alternatively, you can jump-start the battery using jumper cables connected to a functioning vehicle, ensuring to connect the cables in the correct order. After charging, allow the vehicle to run for a while to help recharge the battery further.
To charge a dead car battery, you'll need a compatible battery charger or jumper cables and another vehicle with a working battery. If using a battery charger, connect the positive terminal of the charger to the dead battery’s positive terminal and the negative terminal to a grounded metal point on the car. If jump-starting, connect the positive terminals of both batteries first, followed by the negative terminal of the working battery to the dead battery's negative terminal. Allow the dead battery to charge for a sufficient time before attempting to start the vehicle.
There are typically two cables, one is usually red and the other black. The black cable attaches to the negative terminal on the battery and the red wire connects to the positive terminal on the battery. When removing the battery from the vehicle always remove the negative cable from the battery first. When installing the new battery always connect the negative cable to the battery last.
Use jumper cables to connect the positive battery terminal (red cap, + sign) of your Journey to the positive terminal of the car with the dead battery. Connect the negative terminal (black cap, - sign) of your battery to a solid metal non moving part of the car with the dead battery AWAY from the battery. When you make that final connection, there is frequently a spark- you do not want to make sparks near a battery- they give off hydrogen gas. After making connections, start your Journey, then start the car with the dead battery. Remove cables in the reverse order they were connected, do not let a positive and negative cable touch.
It would be essentially the same as connecting a battery in the car, except with longer cables. You would have to use jumper cables to extend the car battery cables. Be sure to follow ALL safety procedures. Do NOT let anyone or anything metal touch anything else except where you make the connections. Do not touch the metal connectors themselves. I assume there is no battery in the car. I will call the battery that is not in the car the "external battery". First connect the positive ("+", usually red) jumper cable to the positive car battery cable, & then the other end of that jumper cable to the positive external battery terminal. Then do the same with the negative ("-", usually black) car battery cable & jumper cable. The last thing you connect should be the far end of the negative jumper cable to the negative terminal of the external battery. When you are ready to disconnect the external battery from these cables, do so in reverse order, starting with disconnecting the negative ("-", usually black) jumper cable from the negative external battery terminal.
you hook the positive cable,(usually the red) to the positive battery terminal first then you hook the negative cable(usually black) to the negative terminal if you hook it the other way you can get sparks or arcing that can cause damage or a fire PS: if both cables are same color, the negative cable is the one bolted to the frame or the engine.the poitive is bolted to the solenoid or starter
To safely connect a car battery without causing damage or injury, follow these steps: Ensure the car is turned off and the key is removed from the ignition. Identify the positive () and negative (-) terminals on the battery. Connect the red positive cable to the positive terminal first, then the black negative cable to the negative terminal. Avoid touching the metal ends of the cables together or allowing them to touch any metal surfaces on the car. Once connected, start the car and let it run for a few minutes to ensure the battery is charging properly. Disconnect the cables in the reverse order: negative first, then positive. Store the cables properly to prevent any accidental sparking.
