Hi all,
I've got a current leak of 6.55 mA measured at the battery. Already found out there's only 0.03 mA draw left after unplugging the clock/turn fuse. The service manual says a maximum of 1.2 mA is permitted.
This circuit is responsible for the clock (in the dashboard) and the turn signals / hazard lights.
Using this nc700/nc750 service manual I've performed the following three diagnostic tests. And found out that by disconnecting the dashboard cable the current draw drops to 0.03 to 0.04 mA.
All three tests passed.However, at the back-up voltage line test something unexpected happend: the left signal lights turned on. When enabling the hazard lights also the other side lights turns on. In both lights are solid, not blinking. The service manual doesn't mention these lights may come on.
Update: found out these lights were on due to the 12V line making inadvertently contact inside the 16 pin connector.
I noticed meanwhile the battery Voltage was dropping rapidly with all four indicator lights on. When I started the diagnosis it was at 12.8 V and by the end it was at 10.8 V.
Any clue what this could be and how to further diagnose and fix this issue?
This issue causes the battery to drain out over time.
