The battery will loose charge even if it has no loads connected. This happens due to the nature of the chemistry of lead acid type batteries. A fully charged battery will fully discharge in a few months. The older it is the faster it happens. Significant damage happens to a battery that is discharged while a charged battery has much less damage. The ...

are you running an amplifies for the subs? if yes are you using a capacitor in line with the power to the amp and have you check the voltage to the amps signal on wire? As the deck also receives power from a direct source of the battery to retain memory. the deck could be damaged (possibly also directly affected by moisture) and unless you are ...

I would try using a multimeter that can measure DC current to see which circuits are drawing power with the ignition off. The radio should draw some, and the alarm (if your car has one) and whatever circuit handles the remote door locks, but other than that there shouldn't be anything drawing any power. Make sure there aren't any lights or anything that aren'...

There is a product called BG Frig Fresh. It's made to eliminate mold and mildew from an AC. There is a drain under the car, spray in from there, or go backwards and tap a hole in the box under the dash. Then spray into the hole (where the heater core and evap hose meet).

In the most simple terms flushing means you are actively washing the old fluid out using some sort of other liquid (such as a detergent or solvent) rather than passively draining which is just allowing as much as you can to flow out of the system unaided. Does flushing require a special machine? In engine oil terms a flush is done by adding a special ...

From our discussion in the comments, it would appear to me that you possibly have a bad connection of one of the wires on the battery positive post. The starter is getting power, but maybe one of the other wires that gives power to the ignition or fuel pump is not connecting every time. I think adding the jump connectors you are making the connection work. ...

You have the recommended interval from your mechanic and the recommended interval from the oil manufacturer. But you are missing the number that you should start with - the one from vehicle manufacturer. If your vehicle came with a user manual, it's generally in the preventive maintenance section in that manual; if you don't have the manual, look online for ...

A cheap hack is to disconnect the battery every time you stop and leave the car, and reconnect it when you want to start the car and drive. Assuming the car keeps the battery charged while it's running, it's an easy solution. If you want an easier way to disconnect the battery, you can get a switch.

A normal multimeter can measure max 10-20A, and this also for short time only. This current is easily exceeded when the motor is running, or when it's not running and heavy consumers such as headlight or rear window heater are running. This can destroy your multimeter! When staring the motor, it can draw several 100A from the battery, this will definitely ...

Yes it will stop the camera draining the battery, but that defeats the "convenience" of having it on - why not locate a fuse which comes on with the accessory position of the key..

Have the charging system load tested and make sure the battery is fully charged 12.5v or better. I'd avoid disconnecting parts or pulling fuses until you can identify the source of the draw. There are too many computers and circuits that stay active when you turn off the ignition. If you have a multimeter voltage drop test the fuses by placing the leads ...
