A54 service alternator stoped working #ZOOM

Hi guys, 
the issue resolved.
It was 10amp fuse on the positive poll of the alternator.

thanks to everybody.


 

It could be a lot of things. 

If the alternator comes on (Self-Excites) when you quickly raise the RPM to about 1500, it is the Excite circuit and possibly the relay or its connections. This relay activates when the 12-volt ignition circuit is ON. The 12-volt ignition closes a switch inside the relay that sends 24-volts to excite the alternator. This is a very common relay used in many things including autos. Most of the time failures are loose or corroded wiring.

The schematic below was posted here some time ago by Arno Luijten.
