A simple method to make sure that the settings are not lost when the car battery is turned off Modern cars have one problem – when you disconnect the battery , for example, to replace it or perform various electrical works, all parameters are reset . The ECU memory is reset: throttle settings, automatic transmission settings, power window settings, tape recorder settings, and much more. Today I want to offer a fairly simple method that allows you to save the settings of the electrical system when you disconnect the battery. To implement this method, you will need wires , and a couple of hoses . Connect the wires To implement the conversion, you need to remove the negative terminal from the battery, switch the mode selector to " + " mode, disconnect the negative terminal, and then connect the wires, undo the polarity of the wires attached to the pallet. Then, after reconnecting the battery, you need to set the mode selector to " + " mode. By default, the system selects " + " when connecting the battery, and "- " when disconnecting it. The method is almost simple, and is even simpler – fuse To set the fuse , you will need wires , solder and tape . How to set the fuse There are a lot of ways to set a fuse, but the method that I will now describe is the simplest. It is desirable that the fuse be made in a metal canister , preferably glass. The size of the canister should be such that at least 2 meters (6-7 meters). arm. At the place of manufacturing the place of manufacture must be sealed with tape so that the device does not slip during installation . In this way, the fuse is able to work for years, and still be relevant. Of course, it is not connected directly to the battery, but since it is unlikely that you will be there for a long time, then connecting the device to the battery is a good idea. It is also possible to set the fuse in an old battery, but it is unlikely that you will be there for a long time, and since the terminals on the relay board are not soldered, then you will have to soldered them. Soldering of terminals on the relay board On a used car, you will have to connect the terminals of all elements of the power supply system, since there are quite a lot of electronics in the garage. It is best to use a multimeter in voltmeter mode, or a self-made device, as a relaying device. How to set the fuse For setting the fuse, you will need a screwdriver , the "anti-theft" type, with at least one extension, and a screwdriver with at least two blades . The hook with the "anti-theft" type is designed for the car mechanic
