You have to remember ohms law Voltage = amp * resistance. Using some basic algebra you can rewrite the equation as amps = voltage / resistance. Since a short circuit has relatively 0 ohms of resistance, this increases both the amps and resistance which uses more battery capacity,power, and creates more heat.
If no accessories have been added that are draining the battery it is probably the voltage regulator . The voltage regulator will short out creating an open circuit , and the battery will drain back through it .
short circuit , or the battey needs replacing it may not hold a charge
Might be a defective voltage regulator (not opening circuit on shut-down) Or a bad stator. (if the battery doesn't charge at all.) Or an electrical short.
Yes, it can get the battery wet and short circuit it.
I would imagine that there is a short circuit or a Parasitic drain on air con circuit. Often air con is ran automatically and wiring would be linked to ignition circuit. SDS
the current in the drain circuit of a field effect transistor.
A car battery in any car would drain due to a short in the electrical system.
Absolutely. If a diode shorts to ground it can drain a battery in a very short time.
The most likely culprit for a pulsing short circuit and battery drain in a 1993 Geo Metro is the ignition switch or the wiring associated with it. These components can develop wear or poor connections over time, leading to intermittent short circuits. Additionally, check the alternator and its associated wiring, as a failing alternator can also contribute to erratic electrical behavior and battery drain. Lastly, inspect any aftermarket electrical components, as they may not be properly integrated and could create parasitic draws.
Overcharging (bad voltage regulator) or a short circuit inside the battery.
A short will not drain the battery it will blow a fuse. It may be the battery has a dead cell, or some light is on draining the battery. It can also be a stuck relay.
For a battery to "Drain" you MUST have a short somewhere or the "Glovebox" or "Trunk" light is staying on etc. etc. Battery's don't just "Drain" on there own ;-) TommyTrouble
