Hi stuck on electrics again!!http://www.rollaclub.com/wiki/index.php?title=Tech:Engine/A_Series/Alternator_Wiring_Diagram

 

So looking at this can i connect the sence wire back to the main battery charge wire ?

 

The 12v swich from a ignition source,and the charge light from the original alt wiring (originally bosch alt ).

 

This is correct or not?Also wire guage how big or is bigger better?

 

Medicine man ,GJM or one of wiring guru s.

 

Thanks inadvance Rob

Yes. You can just connect the sense terminal to the battery + terminal on the alt. By connecting the sence terminal to the actual battery though, the alternator can maintain the battery at the regulator set point (overcoming any losses between alternator and battery).
