Is it ok to just identify the 12v+ lead and common lead, put a connector on these and hook up the charger?? The converting info states to take the cover off and create new terminals but my power supply is locked up tight. Also is there a way to measure how much wattage these leads can put out?

I used the tutorial that schoey posted (the 2nd link), and had no problems doing it. Should only take ~20 minutes to convert it. What kind of ps do you have? If it one with the push-button power button, then you need to find the power good wire and solder it to a +5 volts line.

If you have an older ps with a big red switch then you shouldn't have to do what I just described.

You will probably need 3 to 4 wires of each +12v and common. I think this is to make sure that it is providing enough amps or watts. You might want to make sure that you are getting the full 12 volts across the terminals, if not, then follow the instructions on that site for putting a load on the +5volt line.

Your power supply should say how many watts it can put out. Or you can just do the math. Power=Current*Volts

For instance, my ps says 200watts, and has the stats: +12v at 8 amps and +5v at 23 amps.

So thats 12*8=96 and 5*23=115. 115+96=211 watts (close enough)

I have a new type supply(don't know the name at this time). I did get it to work correctly and it runs when plugged in. I also identified the 12+, 5+ lines, and common lines. The case looks pretty difficult to get into so I was trying to use the external wires. Can I group several external wires rate at 12v+ and several common wires and accomplish the same thing?

Ok. Thats not much usefull info. Where can we get these and they just hook up to the charger like a battery right? Otherwise, I'm gonna do the Power Supply mod (or is that what your talking about?) because I can get boatloads for free (own a computer company).

Here in San Jose, Santa Clara, there is so much surplus that they leave it out at the front of the store, all kinds of stuff for $1 like at Halted Specialties ,

There's gotta be surplus places near you too or check out BF enterprises in the electronic surplus
search on Google

I picked up 2 ATX power supply 250w for $1 each working on one weekend.

Read the threads on using the PC pwr supply .

There is also a bunch of surplus switching power supplies that can adjusted . I got a bunch of QUALIDYNE units at HACKETT ELECTRONICS in San Jose 408 283 9000 , ask for Mark or Stan .

I use it with the GWS peaker. Has a 12v 15 amp output and also a 12v 7 amp output.
All you have to do is wire up an AC pwr cord to it and hook up the charger to the screw terminals or srew in some banana plug studs so you can use small alligator clips on the studs. You have to change the battery clips on the GWS to small alligator clips

Just follow the directions in the sites listed and you will have a working power supply for your charger. But do follow the directions as closely as possible, otherwise its not safe. Collecting all the 12v and common together in seperate bundles and cutting off the wires not needed, not only lets you draw the needed current, but also makes things neat. You dont want a bunch of loose wires all over shorting, getting tripped over ect...
