hi my p38 dse voltage is 13.06 when engine is running. Was wondering what other p38s read as my voltage appears low didnt realise i had a problem until i had it plugged into faultmate.

13 volts with no load is ok what voltage have you got under load?
All lights on heated screens all electrical loads not wipers then raise to 2k and see what the voltage is should be 13.5-14 volts

The voltage you see on the Faultmate is not the same as the voltage seen at the battery terminals due to volt drop in the wiring. Put a mutlimeter across the battery, I would expect to see more than 14 volts with a fully charged battery and the engine idling.
