Falcon NVRAM problem

Post by gazak28 » Sun Dec 10, 2017 7:12 pm

Hi all,
I am on here to get some advice.
I recently installed an Exxos NVRAM into one of my Falcons and am having some troubles. I am lucky enough to be involved in a small Atari club and Paul one of the members was able to check my soldering, and tested every solder joint with a multi meter. Checking them against Exxos diagrams.
Every time I go through the process of reseting the NVRAM it all seems to go well.
When I switch the machine of to see if the time holds it will not start. I have to take the battery out, unplug the power supply and wait for about 5 minutes. Switch it on without the battery it works. Put the battery in and it is like Ground Hog Day all over again. The battery has been tested too.
Please if someone has had similar problems I would like to hear. I am waiting on some capacitors to try the trick that Exxos has suggested, but just in case that does not solve it, I am open to any ideas.
