An electrical short, or some other battery draing issue. on 1993 Lincoln Mark VIII

93 Mk 8 won;t hold a charge. Some say radio problem. Already removed air-ride system. We like it, but not real reliable these days. Any ideas? 83000 mi. Has new battery and alternator. Always garaged, clean and dry. Thanks for any help.

seek diag for battery drain and have battery tested
Done that already. Battery teated "good". Air ride replaced with more traditional suspension conversion kit, designed for mk 8.
