Common in electrical terms means shared: belonging to or shared by two or more circuits.

The hot wire is connected to the "common" terminal on this device because it is "common" to both the little light that illuminates the switch and the hot side of the switch. If you connect the hot wire to the opposite terminal the switch will not be illuminated until the switch is in the ON position.

Which fuse runs dash lights on 1990 ford tempo

I see from a diagram it is a 5 amp fuse, and it is designated #13. I don't recall the color of a 5 amp fuse, 10 amp fuses are red, and 15 amps are blue, the two most common fuses. It only says it is in the fuse panel, and this same fuse supplies the prndl illum. light, the radio illum., the ash tray light, along with the 4 instrument cluster lights, and a couple of other lights on switches. So if the fuse is blown, you won't have lighting on any of the above things.

If it is not the fuse, you may have a couple or more bulbs burnt out in the dash, it shows there are four illumination bulbs. You have to pull the cluster out to check them, the only difficult part of the job. The power for number 13 fuse comes right from the main light switch, then to the dash and the other illumination lights, they all splice off from the fuse wire out to them. And they almost all share a common ground, so if any of them work, the ground wiring is probably good for all.

Battery isolator wiring diagram

The positives are separated by the selector switch.
Therefore negatives (or negative earths) can be commoned and left connected to batteries.
As a circuit needs to complete a closed loop from battery positive through the selected switch contact through the load 'caravan' then back to negative, the unselected negatives don't do anything.
So, YES WE CAN. :)
Hope this helps.

Cyclone ca-594 amplifier

The protection system will come on if for example the speaker wires are touching, or there is an overload in the system. If you can't get it to clear, then suspect a power transitor has failed, causing a short circuit.

It sounds like a heating element has gone out, you have seriously hard water that has damaged the system or you have a burned circuit. Without doing something I would not recommend with that type of system your only real choice would be to send it back for repair. If it is brand new it should have a 1 year warranty.
