Rob About the only way your 27 could be 24 volt is if the PO was an electrical engineer with a way bad idea! Too much stuff to change over as they were 12v stock. You would have to get into a pretty big "yacht" to run into a 24 volt system.
Probably every one knows this but maybe not so, here it is Given 2, 12v batteries, say 12 volt at 500 amp (for the sake of simple math) If they are wired in parallel you get 12 volts with 1000 amps If they are wired in series you get 24 volts with 500 amps.

It would be highly unlikely that anyone would have converted a c-27 to 24 volts. You can be sure by looking at the back of any device you have on board. It will state the operating Voltage. In fact, the light bulb you are intending to replace .. most probably has the op voltage stamped on it. To check with a voltmeter, simply go to your power panel and measure across any circuit breaker (Positive side) and the common (ground, Negative). With some care not to short circuit, you can measure at any similar point. Such as the Bulb Socket it's self..
