Today I have run continuity test on all wireing within the harness all was ok.
I have power to the lamp at the rear of the OBC, and even with the holder lamps broken, I replaced them by soldering in almost the same size lamps. BMW are asking Ԛ£20 just for that small thing.
My question is "can I test the OBC on its own" away from the car or have I got a duff'en
thanks chris.
