Upon reinstalling the 12 volt battery and rechecking the draw I found that the 6AL box and delay box with throttlestop and launch control solenoids was pulling over 4 amps. I had wired these so they were on whenever the main power switch was on. Those have now been put on a circuit that is only on when the ignition switch is on. Works well with the 12 volt system. Will have to reinstall the 16 volt battery and recheck and try at the track.
