Hi,I have 1998 370 ac. when winterizing this year took negatives off batteries and aft cabin lights stayed on. any ideas as to why?everything else went off

Welcome to the forum.

Cabin lights remain on because they still have power.

Assuming they are DC lights, then there is either an additional battery w/ the negative cable intact, or the AC/DC battery charger has incoming AC power, still providing output DC power.

Thanks so much for your reply. there was no a c power and we couldn't find any extra batteries. I have two port batteries ,2 starboard batteries and 1 genny battery. the lights went out when the positives were disconnected
