Ok, another dumb question! I went to Advanced auto parts and asked for a battery tester for 8V batteries. After they looked at me like an alien I said they are golf cart batteries. They never heard of 8V batteries. Now that I have established the fact that Advanced will not be a source of help for me where do I get one and what kind do I need? Thanks again in advance! My learning curve is pretty much a verticle line at this point.
