I think most folks, myself included, are confused about what you are trying to accomplish. Are you looking for continuity on the unit itself (GDU370 I assume) between the power and ground pins? If so that's a meaningless test. If you want to test the unit simply apply 12-14v and ground from a good battery to the appropriate power pins and see if it boots up!
