- To disconnect a weight cable from the battery.

|
- To establish on the ampermeter (with limits of measurement 0 - 5 мА and 0 - 5 And) the highest limit of measurement. To turn on the ampermeter between a minus pole of the battery and a cable of weight.

An inspection can be carried out by means of the indicator. If the indicator lamp between a cable of weight and a minus pole of the battery does not light up, it is necessary to use the ampermeter anyway. |
- To switch off everything consumers of the electric power, to close doors.
- To switch limits of measurement of the ampermeter until indications appear (1-3 мА it is admissible).
- Taking out one after another safety locks, to disconnect various current contours. If at disconnection of one of contours of the indication fall to 0, here it is necessary to look for a malfunction source. Possible mistakes: the corroded and polluted contacts, the ground wires, internal short circuit in units.
- If in the contours of malfunction protected by safety locks it is not revealed, it is necessary to disconnect wires of the units unprotected by safety locks: generator, starter, system of ignition.
- If at shutdown of one of the unprotected contours of the indication fall to 0, to repair or replace the corresponding element. At loss of current in a starter or system of ignition always to check the switch of ignition and starter according to the scheme.
- To connect a weight cable to the battery.
- If are available, to determine time on hours and to set a protective code of the radio receiver.
