And looks like staring voltage at all positions mentioned above starting voltage drops to 9.7v...
 
What battery is on there?
Some massive black thing. Oldham so guess its something cheep.

Battery is fecked. I think the MF31-1000 fits good battery in my experience and good price, delivered next working day from Battery Megastore.
 
Yeah alternator il do that this evening.
Stole battery out the wifes car for now since its laid up.
750cca 95ah.
 
Need to do some looking with a voltmeter tomorrow.
Only charging at 13.5
Heated seats and screens on and blowers. 12.1
Plan check the engine to chassis earth strap
Alternator output
Then join at starter and at jump start point then battery terminals.
Even if it is alternator dying a 330d one iv sat in workshop is the same

Bit low. Seem to recall a strap on the L322 that rubs through, maybe near the driver's wheel arch? @holidaychicken would know.
 
Did something about the headlining. Bear in mind this has been unused and outside since 2006ish..20200415_173545.jpg 20200415_194729.jpg 20200420_221750.jpg
Magnolia emulsion! If it doesnt last then its only a 5 min job to take it out to cover it with fabric but this cost me nothing :D
 
Alternator done. Easy job. Monitored the voltage on the obc on way home. Sits around 13.8v with everything on.
The plug was diffrent on the bm alternator. so chopped a plug off a donor engine and made a double ended connector adapter basically.
So the original lr plug is there.
Wifes car battery fitted fired up better then before.
All works didn't cost a penny (for now) win win.

Result. Might find an issue with calcium batteries with that set-point.

13.8 volts is no use on a modern Lead/Calcium battery, it will not fully charge the battery. 14.2 is the absolute minimum and on your car it should be 14.7/14.8 volts. You need to get a new regulator with a 14.7 volt set point.
