I just replaced the battery throttle body on my 08 dodge caliber , now the battery light keeps coming on..what's the problem, alternator?

Hello, the battery light indicates a charging system issue. Either you have a cabling issue, an alternator issue, or a wiring issue. Hands on testing and evaluation is needed. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
