16.4. Check of an electric chain of charging

PERFORMANCE ORDER
1. Include ignition.
2. After inclusion of ignition at the working engine the control lamp of charging of the rechargeable battery has to burn.
3. Disconnect the socket from the resistor of preliminary excitement of the generator.
Connect an ohmmeter to contacts 1 and 3 sockets from components. (+) an ohmmeter connect the positive probe to contact 3, and the negative probe (–) – to contact 1.

Prevention

If it is wrong to connect an ohmmeter, it will not show value of resistance



Result


PERFORMANCE ORDER
1. If there is a conductivity shown by an ohmmeter, so an electric chain as it should be. If conductivity is absent, so the electric chain is faulty.
2. If conductivity is absent only on a step 3, check and restore an electric chain of a control lamp. If conductivity is absent only on a step 2, check the resistor of preliminary excitement of the generator.

Prevention

If conductivity is absent only on one of steps 2 and 3, so the system works normally, however, for more reliable work of system it is necessary to carry out an inspection of an electric chain.
