Light Of Battery Stay On When The Car Is Off In 2007 Gmc

Hi, I want to power a table fan (50 watts) using a battery. In India the input power to appliances (fan in this case) is 220 volts / 50 Hz. so can i power the fan with TWO 6 volts 4.5 AH sealed lead acid battery??

Can u please tell me how to do the power calculations? i want my fan to run for abt 4 hours. how many batteries do i need?



(im planing to charge the battery using solar panel but thats another question)
      

Lookin to go camping electric free. I want to buy a couple car batteries just so we can hook up a couple of low watt bulbs. I already have a case for the battery so it will be portable. What kind of cables/wiring would I need to hook a light socket to the batteries? I'm guessing I would need an inverter too, am I correct? Would I also need some kind of controller so the battery wouldnt drain too low?
      

Hi.  This is not exactly home-improvement-related, but I'm hoping some of the electrical gurus out there can answer my question.  I am building an underwater fishing light.  It will basically be a sealed green acrylic tube with LED bulbs in it, powered by a 12V DC battery.  It will be submerged between 2-5 feet.  I imagine it will be used approximately between 2-6 hours at a time, so the cable will not be submerged in water or a wet area permanently. 



Obviously I am doing this to save $$ (they are expensive otherwise), and I find myself wondering why I can't buy an inexpensive extension cord (lamp-cord-style) and use it for the power from battery to light.  I started looking at garden lighting wire, but that stuff is very expensive.



Would auto electrical wire (with shrink tubing) be sufficient (though I'm not sure I can find shrink tubing with enough length)?  Speaker wire?  LOL. 



Any suggestions would be appreciated!



Edit: One thing I forgot to mention is that I don't want the power cord to be heavy at all.  Nice and light is the key!
      

I have a 120vdc treadmill motor that has a motor controller board and a transformer to operate it. My question is is there any way to rigg it up to a 12v deep cycle battery. I was thinking all i would need is some sort of step up transformer 9-1 if they make it or 10-1. I would aslo like to have speed control which i assume would work through lowering the voltage. It runs fine off the 12v batter just not near the rpms i need. I know it will drain the deep cycle very fast but im not worried about that.
      

I have a battery operated 12v emergency light located in my basement. It has two lamps on it. I would like to remove one of them and place it upstairs in my dining room to cover that and the living room. I have some old 14/3 SO cable lying around and wondered if you guys thought if it would be acceptable to use this. Also, can I run this in the wall cavity as long as my terminations are inside the box where I mount the light? Is there any part of the code that covers this or any violation of the code?



Thanks,

Rick
      

Going through a crazy heat wave here in SoCal, and one of my tenants called to tell me that the electricity isn't on in some of his rooms. He turned on his portable AC unit that he has been using all summer and something may have happened.



Downstairs:The dining room light switch, downstairs light switch do not work. All outlets around them do work though, which is odd cause I would have thought they'd be on the same circuit.



Upstairs: The side bathroom light switch does not work, but outlets all work. In the master bedroom (where the AC unit is located), the master bathroom light switch does not work, nor does the master bedroom light switch. All of the outlets do not work either. I used my outlet tester and it gave me the hot/ground reversed lights. I think this means that the white/black wires are reversed on the outlets (has not changed recently).



I went over, checked all of the breakers. Switched them to off, then back on, did not fix the issue. All breakers stay in the on position without tripping, so no shorts?



Checked all GFCI's, hit test, then reset, did not solve the problem.



We unplugged everything from all outlets, and retried, but it didn't work.



I checked continuity between the main power lines, and the output of the circuit breakers, and all were fine. I did NOT check the voltages though, and will do so in the morning when I stop by again.



Is there anything else I should check?
      

I was given a table saw from about 1960 - actually a very good machine - it would cost a fortune nowadays, but a friend who felt he owed me one gave it to me before he moved to Florida. It has a 1 HP motor that has always worked fine and has worked fine for me in tests, but the cord is an old 2-wire version, and I want to replace it with a new cord.



The manual says to use a 10 gauge wire (the cord is about 6' long). I want to replace it with a 3-wire, grounded cord. Do I simply run the neutral wire on the new cord where the old white wire was, the black wire to where the old black wire was, and connect the ground to the chassis?



The switch is a single throw, double pole switch, by the way.



Here's a link to the manual, if that helps anyone: http://vintagemachinery.org/pubs/detail.aspx?id=2007
      

Hello everyone,I have a question about a forklift battery charger i bought. Ok,its an exide forklift battery charger 36 volts. It weighs a ton so i am having to run a 25 foot extension cord to it. My question is,my 220 wall outlet has three holes so i went to lowes and made a 220 extension cord. Now i get to the ac cable coming out of the charger that hooks to the extension cord(plug was cut off),there are 4 wires coming out of the cable green,white,red, and black......the guy at lowes said i could buy a 3 prong plug for it to plug into the female end of the extension cord because one of the 4 wires is probably neutral and i wouldnt have to hook up but the green,white and either the red or black.....is he right? Inside the charger the red,white and black all go to big fuses and green to ground. Also above the fuses it says "factory set to 480 volts ac". I guess my question is,will this charger only work using a 4 prong wall outlet(mine only has 3) and with 4 prong plug hooked to cable coming out of the charger itself or is the guy at lowes right in saying that only the red OR black wire has to be used? Sorry if this is confusing but ive searched and searched online for 3 days and havent found anything. Thanks in advance for any help-Kevin
      

As far as I know every splice needs to be accessible. Is there a way to splice a 6/3 cable in the ceiling without having it in a box? I want to run the cable to the garage for an electric vehicle charger but the piece I had turned out short. I have an extra piece but the splice would be in the kitchen ceiling.

What I've seen in other countries is something like a cast resin shell/box in which the wires are spliced and then resin is poured in the shell/box to completely fill it.



Do you know of something that can be done in this case which can stay unaccessible in the closed and finished ceiling?
      

In a previous thread (Wire suitable for underwater usage), I enquired about what cord types would be suitable for underwater usage because I was building a submersible fishing light to attract baitfish.  Well, the light is done, and the bulb "farthest away" from the battery is by far the brightest in the chain (I hesitate to say chain since they are wired in parallel). 



Attached image "photo 1" is a picture of the light I made.  Notice the bulb all the way to the left is far brighter than the rest.



All bulbs used are the same spec, and look like this:



To wire the bulbs, I cut the flange off with a Dremel tool so that they would fit in the tube.  Two pair of them have their terminals soldered together (neg to neg, pos to pos...that's the "gap" you see in the lighting), and the first bulb in line is upside down, with it's terminals facing the incoming wiring.  The first bulb receives the wiring from the main line, then hookup wire is used to jump from those terminals to the next set, etc. 



There IS one anomaly with the final/far left bulb.  When I was cutting off the flange, I accidentally cut too far on that piece, basically severing the terminals from the bulb.  So, when wiring it into the circuit, I had to improvise and soldered the hookup wire directly into the solder points located on the bulb itself (instead of the underside).  Hopefully you can see what I'm talking about in attached "photo 2."



I have no idea why this anomaly would make the bulb brighter though.  Can anyone think of any other reason the bulb would be brighter?  Unfortunately, I cannot do any readings on the individual bulbs because I did not notice this until everything was soldered into place and the lamp sealed/waterproofed).
