hi i installed my boost controller today and the only thing that is working are the lights behind the buttons. i got it used so i hooked it up to the battery first to make sure it would power on. everything worked when i did that so i decided to wire it up, now the screen isnt working. i called apex and they said i probably shorted the screen out. would it matter if i hooked it to the battery? its 12 volts no matter if its the battery or wired in. also wouldnt it fry it right when i hooked it up if it was to many volts, it worked just fine until disconected from the battery. any suggestions would be great.

 

you sure you hooked the right wires to the battery when you were doing the test..and also are the right ones connected now?

 

yea i hooked the red to positive and the green and black to negative. now when i try to hook straight to the battery again the screen still wont come on, just the lights for the buttons.

 

My suggestion is you follow the instructions to the letter.
