Narrative:

Again during preflight; I do my preflight duties per the aom; which states that I (as captain) am required to test the master light test. As it says; 'some lights will not test but will be checked during systems test'. Problem is that the lights that do not test are illuminating from a electrical short or burned out mechanical issue inside the fire panel. Knowing my system knowledge; I know per frm systems that all fire lights and associated fire master warning lights do not illuminate and the fire 'T' handles do not illuminate. Using our rrm (ramp resource management) model for safety building block known as 'knowledge and skills'; I know that this is wrong and that a faulty electrical short has occurred.after all flows and checks are done then I am required to call the before start originating checklist. Per your own procedures the checklist asked lights test; my response is 'checked'. If I am calling 'checked'; what does it mean if I ignore what I know is wrong; (electrical short). Lies. I will continue to ground aircraft and refuse to fly an aircraft that has or the potential to create an electrical fire issue. I find it an issue that I have brought this problem up before and mtc along with other personnel seem to not take notice of this problem. People seem to think that I am creating this issue and should just ignore it. I in my own consensus cannot accept this.I find it an issue that pilots do not know. Should be added into manual so pilots have it black and white. Pilots say it's not in manual so it's good to go. (Sad statement). I find most pilots have no idea what is right or wrong on the light test.
