Dear Mr.Watson, I wonder if you are able to let me know what proporation of American cars and English Cars are now using electrical systems with the battery positive earthed instead of the negative. I am not anxious to adopt the earthing of the positive until I have satisfied myself that there is really something to be gained from it. Yours sincerely, | ||
