Lucas built both internal and external grounded alternators that run on a M30.
If you wire the ground wrong it will not produce any output.

I don't know that issue, but you can use a multimeter to confirm continuity. Just read both ends based on the color code

This question is mainly for those who have a C320 with a Perkins M30 engine,
although I'll take help from anyone.

 

I am replacing my OEM Lucas A127 alternator with an 80-amp Lucas alternator
from Parts4Engines.com. The wiring connections are the same on both
alternators, but I am not getting any output from the replacement.  One
possible issue is the ground wire attached to the "B-" connection on the
alternator.  The wiring diagram in the Perkins Workshop Manual shows a fuse
in that line somewhere, but I can't find the fuse because the wire
disappears into a wiring harness bundle.  

 

Does anyone know whether the harness really does have a fuse, and if so
where it is located?  Bonus points if you can also tell me where I would
find a replacement if the fuse is blown.

 

Thanks in advance for any help.
