this happened a couple of months ago but the wires are melted from t he starter and under the battery tray i think i put the battery in backwards and i dont know if there burned under the front to go to the headlights because theres that black plastic coating. also should i get a new alternator and any other parts the wires were connected to thank you
If the battery went in backwards that means car wasn't running I doubt any damage to alt but you can remove it and have it tested at most auto parts stores. The only other thing maybe is voltage regular as wires run from alt to volt/reg. Other circuits wouldn't be live unless car was running.
