My progressive electronce 2003 Pulser wont keep a charge. In years past we would send them to Progressive but this has been 5-6 years since we sent something and in that time frame unless Im mistaken GreenLee bought them out. I did take the locator apart and the battery has some corrosion on it and this must likely is the cause. For good measures I would like to send it in and get it all checked out. Any help is apperciated.
