Greetings EEVBees:
--I am trying to repair the pictured Garmin StreetPilot III for a friend of mine. It is quite a nice unit, and well worth repairing. It even functions as a speedometer.
--As you can see from the attached pictures. The ability of Duracell battery juice to eat through all manner of things is truly amazing. These cells have a durable ability to destroy things long after the charge is gone; hence the "Dura" in the name.
"Sir we could fix the X9D disintagrator if only we had a substance that can dissolve unobtanium." "Your in luck Sergeant Thorkild, we just happen to have a Duracell battery that has been kept in a stasis field, in order not to eat its way out of the osmium-iridium safety container"
--Have a look at the last picture, g7. I only see one trace going in to the obliterated area and one coming out. I propose using a conductive pen to reconnect these traces, and to repair all the other bad ones. Judging by another ring structure on the board, I do not think any traces connected to the one in the picture. This attempted repair will not be any fun, the traces are very very fine and close together.
--If the above does not work, I am not quite sure how to proceed. It seems very unlikely that I will ever find a picture of the PCB. I may buy another unit, working or not, if it is cheap, just so I can determine the correct routing.
--Any and all advice and information on this problem, would be appreciated.
--P.S. If any one can tell me how to get the pictures into the body of the text, rather than at the end, I would appreciate knowing. Thanks.
