Davtron M803

My Davtron clock/OAT/Voltmeter is having problems with the clock section. This is the original installed in a 2001 T182T.

Does anyone know whether, as installed, Cessna hooked up the "keep alive" pin directly to the battery or whether a AA battery is used on the back of the clock? I can't see the back of the clock looking up under instrument panel and before I take the seat out to crawl up there further, I am trying to determine if it uses a back up battery or if the clock section is Tango Uniform.

Any thoughts are helpful

    Cw..my 877 davtron has a backup AA battery on the back of it.. do the Google thing and download the ops manual if you can't find it in the paperwork for the aircraft. Cessna's normally have a fuse on the firewall for clock power. Carl
