It all started when one morning i came out to drive somewhere and my battery died. No doors were open or anything was left on when i left the car. Jumped started the car and then drove fine on first start up. Then when i started the car later everytime that i would accelerate past like 1500 rpm all the dash lights would come on. The brake light, abs, the triangle with exclamation, airbag light, seatbelt light, engine light and also my speedometer woud bounce up and down from 0 to whatever speed im going. Also all the electronics in the car would stop working. Im talking radio,a/c, windows, blinkers, window wipers, sunroof, etc the list goes on.

So i suspected my battery was going out so i had it tested and the results were a bad battery. So i got a new battery, but of course this still did not fix the problem. What else could cause my dashlights and electronics to go on when i accelerate and go off when i deccelerate?

Your alternator could be bad. My e36 did the exact same thing when my alternator went.

I could test it but the alternator does recharge the battery if i drive.

It could be that it's not putting out enough charge to keep up with the draw on the battery. Who replaced your battery? Was it reprogrammed to the car?

After you program it, if that doesn't help, I'd check all the wire coming/going from the battery. Make sure they aren't frayed or anything. If all seems good, get a multimeter and check the voltage at the battery, should be putting out a little over 12 V when off, and around 13-14.5 volts when the car is running.
