what do you guys use?
what have you figured out that has made it more useful?
i watched a vid last night of a guy who kept his hooked up to a powered on radio ,, it went dim but over the course of many minutes of time, the side mounted volt and ammeter would react to things happening in the set and the volts would drop and current would spike, and the bulb would quickly let out moments of glow. to me this is something you would never be able to easily detect without a dim bulb tester.
i am considering making one,, a guy on youtube also uses 4 bulbs in parallel (2 40w & 2 60w) on the line hot side with a side amp and volt meter.
this got me to thinking about doing this....
line power to one side of a Pot,,, then the wiper out to the bulb, then the other side of the bulb to the hot leg input to the radio,, then the N leg back around unbroken.
i also found it interesting that one vid shows how you can use a dim bulb tester to verify your radio is not AC wired backwards. this is something we could all do visually but........... still a nice quick visual aid.
so what do you guys do,, what do you have,,, what have you added on to make this even better?
as a side note,, in telecommunications we still use this concept when dealing with the addition of a new battery string.
example, we have a 2000A dc plant floating at -54vdc. tied to the - & + buss work could be several 2180AH batt strings (about 7901 pounds each) all charged up and proteted by 1200A breaker disconnects on each battery stack. to add another battery string, a portable charger is used like something along the lines of a 4kw unit. this new battery is wired to the overhead dc buss and back to the new battery stack 1200A disconnect but the disconnect is OFF. when the precharger gets my new string close to the -53vdc mark,, put one wire of the lamp on the hot leg of the existing battery bus and the other lamp wire on my new battery string hot bus. if the lamp comes on,, eventually it will go out and its safe now to flip on the new battery string 1200A disconnect.
