PERFORMANCE ORDER
1. Connect the voltmeter between the plug 30 (A) of the plug of the relay of management of a warming up and the case. The measuring device has to show tension of the rechargeable battery (about 12 V).
2. Otherwise check the red wire going from a connecting block (X12/3) to the relay of management of a warming up for break.
3. Turn the ignition key on a warming up and connect the voltmeter on a counter 1 (plugs 15) of the 6-shtyrkovy plug and the case. Preset value: tension of the rechargeable battery (about 12 V). If tension is absent, then check for break it is black / a red wire from a safety lock 23 (the unprotected party) to the plug, a counter 1.
4. Connect the voltmeter to a counter 1 (+, the plug 15) and a counter 4 (–, the plug 31). Preset value: tension of the rechargeable battery (about 12 V). Otherwise check for break a brown wire from a counter 4 on the case.
