Just replace the battery but the gauges radio an AC is not working fuses are all working

Recommend having qualified personnel perform *hands-on* TESTING to determine exactly what has failed .. IF this happened immediately following battery replacement - suspect missed blown fuses or failed circuits.. Many times battery polarity gets reversed during battery replacement.. There is no protocol for repair.
