I've actually heard a bad thermostat can cause the evaporator core to malfunction.I've also heard of some a/c compressors will shut off if the engine temp gets to high which could be a thermostat issue.
No, the thermostat has no effect on the battery or on the A/C. A thermostat either works correctly or it will stick open or stick closed. Sticking open will cause the engine to never reach full operating temperature, and as such your heater will not work properly. A thermostat stuck closed will cause the engine to overheat.
Positive to positive, negative to negative if you are asking about installing one battery in a vehicle.
The battery cable that is grounded, is connected to the body of the vehicle. Sometimes it is the negative cable & sometimes it is the positive. You need to check which cable is connected to the body of the vehicle.
In a negative ground system, hook the vehicle ground (frame) to the negative of the first battery, positive of that battery to negative of second battery and the positive of the second battery back to vehicle positive. ( starter or starter solenoid) If you are hooking 2 12 volt batteries in series you will have 24 volts.
Depends on the vehicle, but normally it bolts to the engine. The negative is the ground cable.
Dead short in the battery. Battery can explode and damage can be done to the electronics in the vehicle.
First off you must have the same type batteries. Connect the positive post of the first battery to the positive post of the second battery. Then connect the negative post of the first battery to the negative post of the second battery. Now connect the positive post of the first battery to the positive connection on the vehicle. Then connect the negative post of the first battery to the negative cable of the vehicle. Click the link for a diagram.
Take the # 1 battery and connect the positive cable to the vehicle. Then connect the negative cable on # 1 battery to the positive post on battery # 2. Finally connect the negative post on battery # 2 to ground on the vehicle. You will have 12 volts but only the amperage of #1 battery.
Something on the vehicle is on pulling power.
Disconnect the negative cable.
Remove negative first.
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.
the main negetive battery lead should run straight to the engine block
The difference between these two battery codes is the arrangement of the terminal posts. When the battery is installed correctly in a vehicle, as you're looking at it from the front of the vehicle, a 27 will have the negative post on the left side and the positive post on the right. A 27F battery has opposite post positions...positive terminal on the left and negative on the right.
The vehicle battery is located below the trunk floor. Jump-start positive and negative posts are located under the hood on the driver's side of the vehicle
No, that cable is connected to ground, so it cannot short out.
Ground it to the vehicle frame or engine.
Nothing unless you connect the negative cable to the positive post. When you do that you will destroy the battery and it may possible explode. You may also damage the electronics in the vehicle.
If thermostat does not open - Vehicle will overheat in a short time - no heat If thermostat does no close - vehicle will not get to normal operating temperature - no heat
You can take it down to a shop and get it tested, but if you can not afford that, you can take the negative battery cable off of the battery while the vehicle is running. If the vehicle dies, you may have a bad alternator.
Negative terminal is grounded to the vehicle. Because the system is a negative ground system. Electricity will not flow unless it has a path to ground.
The term, 'negative ground' or 'negative earth' refers to the system of chassis-grounding, or chassis-earthing, used in vehicles. With this system, the negative terminal of the battery is directly connected to the metal parts of a vehicle, while the positive terminal is connected to the various electrical devices (lamps, etc.) using insulated conductors. The vehicle's metal parts ('chassis') then act as the return conductor to the battery.
The red battery cable is the positive one. The positive cable supplies the voltage to the starter and the main power center, then distributes it to the rest of the vehicle. The negative (black) cables supply the ground to the entire vehicle, which is what makes the circuit complete and allows the electricity to work.
Battery connectors are what connect batteries to devices so the device can get power from the battery. Electricity is the flow of electrons, and a battery has to have a way for the electrons to leave (negative wire) and return (positive wire). Thus the terminals on the battery are what do this, and battery connectors in a device or vehicle are what carries the electricity to the device or vehicle so it can be used. For instance, they electrically connect the battery to a laptop to power the computer.
Because there may be a spark when you connect a jumper cable negative clamp to the battery post which can cause an explosion. Batteries emit hydrogen gas which is very volitive. Always connect the negative clamp to the engine or another ground point on the vehicle.
