ok well i originally had the battery light come on so we checked the alternator and it tested bad and changed the voltage regualtor, back to working.. occasionally.. then randomly that light and the brake pad light and the parking brake light wil flip on... now from start to finish the 3 lights will be on but at around 70-75mph the lights dim a fair bit... loose ground somewhere??.. when we checked th ebattery last it didnt seem to be charging.. but the car has started with very little problems (none that werent there to begin with.. damn you michigan coldish weather) sooo any ideas? the only thing i can think is a loose ground somewhere... not the battery btw.. oh and lately after the car is started ill put it into drive and the car will stall immediatly.. start it again give it a lil gas and its fine.. is that just due to cold weather?... any help would be great thankss
