I did a test run with the D3, only power installed and no remote turn on wire hooked up, so my amps were off, and I drove from my house to Sears (about a 15 minute drive) with the unit on the whole way. When I came back from Sears (10 minutes in the store), I put the key in and put it in the on position to prime the fuel pump. I knew immediately what happened... pump started to fill, normal ding, lights dim a little and DAMNIT! Battery is dead. Click, click. I unhook the harness to the D3 and still click, click. I pop the trunk (its a bmw, battery is in the trunk) and get ready to have to jump
