The problem with the dash lights staying on is more than a switch or simple circuit problem. In the beginning the problem was intermittent. This however, has become daily occurance. I have to disconnect the battery at night to prevent discharge. The manuals are unclear as to the problem and mechanics appear to be using trail and error. The problem could be connected to residual voltage in the fuel pump circuit. At this point the problem is not fixed. Trouble points to lighting module.
