parallel battery wiring is hooking 2 batteries together in parallel series give you double the volts Clarification: Parallel battery wiring is where two or more batteries are hooked together in parallel (i.e. both/all positive battery terminals are wiredtogether, and both/all negative battery terminals are wired together. This results in a battery voltage which is the same as that of the individual batteries (typically 12V in most cars). The reason for doing this is to boost battery capacity- two identical batteries wired in parallel give twice the electical storage capacity of one battery. No increase in voltage is obtained with parallel wiring. Series wiring is where two or more batteries are hooked together in series (i.e. positive terminal of the first battery is hooked to the negative terminal of the second battery). The resulting voltage is the sum of the individual battery voltages - if two 12V batteries are hooked together, the resulting voltage will be 24V. No increase of storage capacity is obtained with series wiring.
A location to secure it, and proper wiring. You will need to wire it parallel, not serial.
Parallel
Car headlights are typically wired in parallel. This means that each headlight receives the full voltage from the battery independently of the other headlights, ensuring that if one headlight goes out, the other remains functional. Wiring headlights in series would result in a decrease in brightness due to voltage drop across each headlight.
Series is better, it can handle more flow to it.
Could be a few things, weak alternator, bad battery, bad wiring. If you have a subwoofer in your car with no battery cap that will certainly do it.
Replace the wiring that was burnt.
Sereies, with each cell about 2.2volts
The batteries should be wired in series. Electrically, it looks like this: Positive lead to car (+ -) ----- (+ -) -----(+ -) Negative lead to car Each set of parentheses represents a battery, the dotted lines are wires connecting the middle battery to the battery on each side. This will give you 36 volts at the positive and negative leads going to the car. The other option is wiring in parallel, which gives you 12V, but triples the load capacity.
I'm assuming you want dual batteries for increase amps /hour off road use.If you want to get 12 volts out of 2- 12 volt batteries you will be wiring them in parallel. Wiring batteries in "Parallel" increases there combined Amp/hour capacity, but their voltage stays the same. Battery 1 Positive, to Battery 2 Positive, and Battery 1 Negative to Battery 2 Negative is Parallel wiring, retaining the voltage rating of either one of the batteries. I suggest adding a "Battery Cut-Off Switch" in the circuit.Try doing it outside your vehicle and use a multimeter set to DC volts and test for 12-16 volts (higher readings would require it be on a charging system).If you do this wrong and do not test it first YOU MAY FRY your vehicles wiring system by overloading the 12 volt system by running 24 volts through it.
COmputer, loose battery, defective battery/volt amps or loose wiring harness/ wires grounding out somewhere
Take of your glasses Stevie Wonder look at battery terminals
A car's electronics turn off if the battery is defective or the wiring is damaged. This will prevent electronic components from receiving the power they need.
