Hello guys ! Im looking for any suggestions on how fix this major issue. I have a 2008 Acura TL. Recently I was getting the battery light on my dash. Spoke to someone about it and they suggested as the Car is on I disconnect the battery and see if its my Alternator. ( The bolts to hold the Alternator previously came off and the Belt slipped don't ask me how that happen im not even sure ) Unfortunately I did do that. Now I have no power, all my fuses burned and were replaced. Im getting the TMPS on my dash. The gauge to read my fuel stays in the position where I have fuel. And now it has no power what so ever, battery was changed and it seemed to drain over night. Not sure if my ECU (ECM) burned out. The mechanic tried putting the reader and could not communicate with the car. The key indicator was on my dash board and the car can't read the key. Any thing on how I can fix this issue.

Thanks.

In general, you should never disconnect the battery on the running car. Modern electronics aren't really a huge fan of the non-filtered output from the Alternator. The battery acts as a capacitor and smooths those pulses out. I know when my battery cable broke, my TL would not stay running on its own.

Chase down your battery drain issue first. There are plenty of threads on here that describe how to do that. My guess is your alternator is failed. But until you stabilize power, don't expect any of the electronics to behave at all.
