If i sit with my car off, the battery gauge will sit a 10 or 11, but then all of the sudden(no particular time period) it drops below 8. I recently disconnected the smog pump and the ac./ I tape up all the unused connectors, but no luck. Is it a short maybe? I had to replace my floor mounted dimmer switch (as described in the tech article). Could this be shorting out on the floor pan? The lights still work fine. Any suggestions would be greatly appreciated.

it could be the battery, have it load tested.
