Hello folks! Am new to this forum and have been dying for a Whites for years (just posted this to the White's forum as well). In a fit of insanity I purchased an old White's Ted Williams 'treasure locator' off ebay (until I can afford an XLT, which will be quite a while!). It was listed as "like new in working condition". As luck would have it, it will not work. Before I am forced to return it, I hope someone can advise me. Problem- there are two battery packs, a white and a black. Black is nine-volt holding 6 AAs, and it registers on the battery intensity meter. White pack is 12 volt with 8 AAs. White battery pack does not register on intensity meter at all- one of its battery connectors is pretty corroded with rust. When the woman shipped it to me, she had the black wire connected to the white pack and vice versa. With it connected that way, each battery pack registers on intensity meter, but both only barely. While it was on, I managed to acquire a small beep over a quarter on my floor. Question- (probably dumb one, too)- is it possible to replace the white pack with a twelve volt battery instead? Is this crazy? Is it possible to remove the rust off the one contact piece? Should I just return it and start saving up with vigor?? I need help! Thank you very much for your time. Erin
