Good day,
I have some sort of electrical problem with my 85 740 (and who hasn't?).
The other day I noticed that all the indicators did not come on when I turned the key. The car did start however.
All that comes on is the up-shift indicator, the oil pressure warning light and the seat belt indicator.
Drove the car that day.
Next battery was dead. Still there is an issue with indicators. I assume battery is not getting charged.
Charged battery cleaned battery terminals and small ground to chassis and car started. Disconnect the small ground wire and the car will not run.
Indicators are still not right.
Battery and alternator are both fairly new. Failure of either of these would not affect the indicators once the battery was charged.
I can hear what I believe to be a relay clicking under the center console (seat belts?).
Seems like I have lost ground somewhere.
Before I start tearing the dash board (facia) apart?
Where are the grounds in this car? Where does the instrument cluster get ground? Where does the electrical panel (relays and fuses) get ground?
Is there another chassis/body ground?
What would cause the battery to die (or more probably not get charged)?
On cold days, indicators take a while to come on. Car will not start until indicators come on (I suspect that is normal). Changed fuel filter and delay seemed less.
TIA
