MM, Jim,
Thanks for the information on the contact cleaner, I was able to get a can at our local ACE hardware. I also got a G.U.M. bridge brush at Walgreens Drugs (used to clean under/between teeth and dental bridges), it fits nicely into the female Deans connector. I think when I soldered the Deans connector to the battery some of the flux got on the other side of the plug and caused the charging problem. All clean now.
UPDATE: I tried a few tests and found that just cleaning with the contact cleaner didn't get things totally clean. I needed to use an Xacto keyhole blade to scrap and clean off the contact surface, also found a YouTube video on loosening very tight deans plugs. It helped to allow smoother connection after the scrapping and reclean with the contact cleaner. I then did several connection tests in my watt meter and the ESC in the ship, all was fine each time.
Thanks, DennisT
