Re: Battery drain
Check your door switch and or circuit , also look at your light switch . Make sure the battery is good , have it load tested . For checking parasitic loads , remove the ground cable and reinstall it looking for a spark when reconnecting it , this indicates a draw on the battery . Disconnect components , like the starter and the altenator individually . With each component disconnected , reconnect the ground cable looking for a spark . If the spark disappears you have found your draw or parasitic load on the battery. This can also be done using a amp clamp on the positive and or the ground cable actually seeing how much amperage is being drawn with the load being applied . When the amperage load drops you usually find the component or circuit causing the parasitic load on the battery . Good luck
