Few electrical problems 2001 Conv v6:

The cluster panel when i try to start all needles go to max and because battery is being drained it will not start but will start if I jump. Running it can run fine and when idle the car shuts off.

It was drawing from battery yesterday, started taking fuses out to find what was causing the draw didn't notice a change on any of them. Decided to try start the car, all problems had disappeared and car started fine.

Main problem with it is acting up, try to start it kills the battery and cluster all needles shot to max and car will shut off while idle but when something resets car works fine until it wants to act up again. Can be 1 day or 5 minutes later.

Sorry, I don’t have an answer. There never is a silver bullet for electrical issues. Especially when there is aftermarket components involved. First, I would say to disconnect all aftermarket components to rule them out. If you still have a drain, I’d like to verify how you are physically testing for the battery drain (where you attached your meter leads, were the negative & positive battery terminals connected or not, what you had your meter set to, how long you waited after pulling each fuse before continuing to the next, what amount of amps you would consider excessive). I’m sure you did it correctly, I just want to make sure so we don’t go down the "rabbit whole”.
