Want this question answered?
the most likely cause is a flat battery and or dirty battery terminals check all electrical connections from battery to starter (hope this helps)
you have a dirty battery post
This depends what Earth Terminal you mean The one on the top of the battery, You may have a bad battery. Disconect it and come back in 24 hours and see if it is dead. Not dead means that there is a short in the electrical system and this terminal needs cleaning. If the battery is dead the battery is bad, replace it. If this is another terminal and gets hot and stays hot it means there is a large draw on the system and this terminal is dirty and requires cleaning. The hot terminal is allways the highest resistance in the system. Good Luck
no it doesn't Corrosion on the top of a car battery can allow electrical flow from one post to the other which will drain the battery.
The terminals should not get heated up. If one is getting heated up it probably has a dirty connection. Ventilate the area and let the battery cool down before working on it.
There are two related causes for any connection to melt. The resistance of the connection was high causing excess heat OR The Power draw was to high for the connection. In your case either the connection was dirty or there was short further down the wire.
That's usually a low battery or a dirty battery terminal. Check the terminal first, see if it's corroded or loose. Next, understand that the battery is simply an electrical storage device. The battery can be bad or the alternator can fail and the battery will not have enough stored electrical energy. Before just replacing a battery, always check the charging system to make sure it's working properly before assuming that a battery has failed.
Battery connection, dirty cables, starter/solenoid getting weak.
Turn on any light in the car, if the light gets very dim or goes out you have a bad (or discharged) battery. Its remotely possible that the terminal connections on the battery are corroded or dirty.
* Voltage Regulator * Defective Battery * Dirty Battery Post Connections * Alternator/Generator problems
Its likely either the battery connections (terminals) are dirty, or where they connect is...or the battery while showing a charge is bad when on a load. If it starts with a jump from another car...it's the battery.
The most likely cause is a dirty fuel filter that starves the engine.
