yeah it should have ran with the battery off though

 

ok after readin ur post, i have da same problem, but its just my odometer. it flickers wen i have my headights on. is it da same problem

 

my battery is only a few months old also, should i just go buy a new one?

 

my issue was anything that had power..... iv also had a bit of dimming with all the lights but not like this, at night it was like the headlights were turning on and off, but after the batter the only thing i notice is the dome light dimming a bit....
if it gets worse try a battery with higher running power.... stock is like 520v and the one i just got is 575v (or amps whatever it is) seems to be alot better!

 

cool, but i just bought this damn battery lol
