Grounding problem? (going with tester in engine room)

ferruccilorenzo <ferruccilorenzo@...>

With the 24V alternator disconnected from the electrical system, I tested the resistance with a tester between the black cable from the battery service (normally connected to the alternator) and the metal frame of the motor. The electrician told me that the resistance would have to be nothing, but in my case it is several Ohm. In your experience, this mean anything to you? There may be a problem of grounding in your opinion?

Thank you and I wish you fairwinds!
