What is the voltage output for an alternator belonging to a Mercury Sable 93 suppose to be?
i would think it should put out from 12 to 15 volts.you will need to check output also with lights on an if it drops in voltage you probably have a bad alternator,most auto parts stores can test the system for you.
Why would a tube light be flickering?
Most likely it is coming to the end of its life (you can see this if the ends are darkened) or it could be the "starter" that need replacing.
Is thermostat not working the reason for fuses blowing?
What follows is a very general answer.
If the questioner could add some more details to explain what kind of appliance or equipment is being asked about, then it is possible that a much more helpful answer could be given.
An electrical thermostat's element operates a switch. If either the element or the switch get worn out or damaged, then the switch may either stay open all the time or it may stay closed all the time.
If the switch stays open all the time there will be no current supplied to the appliance and it will stay cold. If the switch stays closed all the time the appliance will overheat because the current does not get turned off when the normal operating temperature has been reached.
If an appliance has been allowed to overheat then the insulation on internal wiring, or other internal parts, may have become damaged in such a way that a short circuit could be caused. Such damage would make a protective fuse blow every time the fuse is repaired or replaced.
If this is what is happening, the appliance itself will have to be repaired or replaced.
