Hello EVERYONE, (NISSAN Y61 TD6) I have a sudden electrical failure, the tachometer does not work, preheating light off, air conditioning (only air conditioning, air conditioning does not work) and the Czech engine light (d usual it stays on since I changed the pump to a mechanical pump) but now it is off. I checked the fuses and relays all working. Do you have any suggestions where this multiple failure could come from. Thanks in advance. FRIENDLY
(sorry for my English)
