Use an ohm-meter across the terminals. If it is good, it will show no or minimal resistance. If it's blown, it will show open.
When you had it plugged into shore power, did you have your 12v shutoff turned on? Some coaches have to be turned on to charge. Your chassis batteries don't necessarily charge when on shore power. Not all coaches have a charger for them, but a Trik-L-Start is an easy addition to keep the chassis batteries charged.
