If there is a load on the system, the voltage will drop. Suppose you ran the radio for a while before you start the car and the battery is down a little, the voltage will read 12.8 Volts and then creep up to 13.8 V. The max charging voltage can reach 15.2 volts.

A good test is to start the car, let it run for a moment, disconnect the battery cable. If the engine dies, you have a changing problem. If it keeps running, reconnect the battery and take a voltage reading. It should read a little over 14 V.

As far as the RTS, you will most likely have to disassemble the steering colume and replace the switch. If it is a standard GM colume, it is not that bad.

If you need details, just ask.

Hope this helps.
