How does a diode work on a 12V battery?
A diode test function meter will light up the LED when correctly applied. When it is lit, the black test lead will be attached to the cathode, and the red test lead will be attached to the anode. When you are sure which lead goes to which, it is time to solder the wires to the 12v battery.

Why are the 12 volt lights working on shore power?
With the 12 volt lights working when on shore power means the charger is working. Look for a large fuse between the batteries and the charger 12 volt output feed to the positive coach battery terminal (s). With a meter you should read a voltage at the positive terminals. They will read very low if no charging voltage is present.
What makes a 12 volt light bulb work?
If you have power to the socket, you’ll get a reading of 12 volts or more; if you don’t, it’s time to move down the circuit toward the battery. There may be different components between the battery and the light bulb itself, including items like switches, fuses, buss bars, and circuit breaker panels.
What’s the run time of a 30 watt light?
(Amp Hour Rating of Battery / Total Amps = Total Run Time). For example, a 30-watt COB draws about 2.5 amps., so a 8 amp hr. battery would run the light for about 3.2 hrs. (8/2.5= 3.2) For those of you who need a smaller battery that will fit in a back pack, the compact batteries listed below will provide good light for a limited amount of time.

How many Watts Does a battery Christmas light use?
Batteries store such a tiny amount of electricity that they’re usually rated in milliamp-hours instead of amp-hours (mAh). 1800mAh is the same as 1.8Ah. A typical 50-bulb strand of (non-LED) Christmas lights uses 25 watts. So each bulb uses about half a watt. (Remember that, we’ll use it later.)
