hey guys i got a reply back from them and heere is what they said to do to fix this!
Try doing this test:
Connect output clamps to battery posts.
Press and hold CHARGE RATE button.
While still holding the button, plug in AC power cord.
Once AC power cord is plugged into outlet release the CHARGE RATE button.
This will set the processor into a Manual 2 amp mode. Leave this mode go for
About 1 hour, after that time unplug AC power cord and then re-plug AC power
Cord for the processor to reset. Now any selection you choose should see the
Battery and begin charging the battery the rest of the way.
