It can carry voltage, but NOT CurrentHi so i have confirmed the first point they earth goes to starter i think is fine checked the voltage down there and its matching the reading from the battery. Which is 12.46 so really wondering if its the starter motor failing.

I had a poor connection on my starter, ok cold, went dead when warm
