after I bought my 1987 Toyota Celica GTS from my brother, the headlight as well as the motor to make them pop up and down. Also, the tail lights now don't work I ask my brother about it and he said he caused an arc between the battery, battery holder, and the hood when taking out the battery before I bought it from him everything did work before then. So I have already checked the fuses and relays and replaced them as well as a new battery but nothing changed I don't know what to check for next if anyone has any ideas on what I should do.
