GPS Internal Battery Problem

[yorty]

Hi, I have a Garmin GPS II plus which had a dead internal battery. I replaced it (I am a electronics technician by trade) but the GPS only turns on for about 2 seconds and then turns itself off again. I also replaced a friends internal battery in his GPS 12 but it doesn't turn on at all. I have new AA's in both. Is there something else I have to do? I've measured the voltage on both and there is power coming from the AA's and internal batteries to the motherboard. Any help would be great.

Thanks in advance

You will get better technical advice, but for now, have you read the ' instructions " ? In relation to changing battery and in particular if you have ' initialize " the unit.

Hope you solve the problem.

Thanks Phill, I can't find the instruction book at the moment but I have seen it recently so I can't be to far away. I reckon it'll probably say send it back to the manufacturer but you never know.

google yorty google.

You might be able to scratch up a manual on line.


how are the terminals on the internal battery.

if the battery was an AA......... are you sure it wasn't a 3V lithium not a 1.5V.

Any internal back up battery that lasts more than a few years will probly be lithium.........and not much electronics will run on 1.5V.

cheers
