Check fully charged battery

Set the ammeter (with a limit of measurement of 0-5 mA and 0-5 A) highest limit of measurement. Turn on the ammeter between the terminals of the battery and the cable weight. Connect the positive lead of the ammeter to the positive pole of the battery, negative cable ammeter - to the negative battery terminal.

Turn off all electrical consumers, close all doors and the trunk, turn off the ceiling illumination of a motor compartment.

Switch the measuring range of the ammeter to decrease until, until there any evidence (permissible value range of 1-3 mA). Taking out one after the other fuses from the fuse block, remove or tamper with any electrical circuit in series. If the opening of one of the chains readings will drop to 0, then the chain should look for the source of the fault. Troubleshooting: corroded or dirty contacts of electric sockets, frayed wires, the internal circuit in the electrical components.

If protected fuse circuit fault is detected, disconnect the wires from the fuse unprotected devices: the generator, starter, ignition system components.

If you disable one of the unprotected circuits ammeter will drop to 0, repair or replace the appropriate item. When leakage current in the starter or ignition system, always check (in accordance with the scheme) the ignition switch and starter.
