Battery died turbo timer stopped working

[missionx96x]

Its as simple as that. My car has been sitting for about a week and all of a sudden I go outside to start the car and its dead but the turbo timer is lit up blue but theres no digital words or numbers. I jump the car everything starts right up but the turbo timer is still lit up blue but doesnt work. Its a greddy full auto TT. Does anyone know what may have caused this?

2 weeeks ago, my alternator died/ I was drivng and car stalled/ and during this period all the gauges started reading eratically and wrong, incl. TT/Greddy/, but after that I changed it and everything went back to normal.

Mess around with the grounding. The little wire that goes from your battery to the fire wall and make sure its tight.
