I have an old CHRISTIE 6-12-24 volt battery charger that has had way too many various persons working on it. I am wondering does anyone have any information on it. As I said it is a Christie 6-12-24 V charger, Model #QRC. There is almost no information on these chargers on the internet, would be very nice if could find a schematic. Any help appreciated.
Thanks

Hell ETxJohn,

Yes there is! I Just put in the info on the search bar, it came right up,

Guido.

I don't know where you are looking, yes there are places that sell some new ones. Some places that are selling obsolete parts. Try finding one with the SERIAL number I posted. Furthermore try finding a Schematic that I posted that I needed.
I appreciate any constructive help. Thank you.

Hello ETxjohn

I typed the following in the search bing bar: cristi 6 12 24 volts charger schematic. Many came up and one
was 6 12 24 volts. Try it and see. I can try to paste the link maybe?

Hello Guido,
I have looked at nearly all those, no help. This is a very strange charger. The output goes thru basically a Ford 12v starter solenoid, which is controlled by a 3300uf 35v cap. This cap has been booger wired thru two 12v bulbs. Somehow this solenoid is for polarity protection. therein lies the problem with the charging. I can get this to charge by disconnecting all this but the voltage runs wild. A schematic would be very good. Sorry for this long post, but this thing is STRANGE. Thanks

Hello ETxJohn,

The capacitor must be receiving voltage to enable the solenoid tO CLOSE and open. The bulbs were put there
TO simulate capacitance or resistance built in the cap? I would think that maybe the capacitor is bad?
That is a strange setup. But it sounds like the capacitor is just a switch on or off either in the charging
circuit or a voltage tap. When voltage drop the cap bleeds of and the charging stops?

Hello Guido,
I spent several years of my life designing 7.2KV, 12.4KV and 34.5KV distribution lines in Houston TX. In fact I designed the first two 34.5KV distribution circuits that Houston Lighting & Power ever built. I have wired several houses and barns, but this is kicking my butt. Yes the 3300uf cap. was bad, and I hooked a 1200uf cap. in the circuit. This regulated the voltage, but too high, approx. 16.5 volts on the 12v setting. I know the correct cap. would probably help but I still can't figure out the solenoid, which I wired around. If you think it would help I could draw how this is wired
Thanks for all the help

Hello ETxJohn,

Yes it would. The stater solenoid switch got my curiosity. I am familiar with them. But there are some
variations. A manual automotive transmission would have a single center wire to activate the solenoid. Auto
transmission would have two. Different grounding thats all,

Guido.

Hello Guido,
I'll try to draw it up tomorrow
Thanks

Hello ETxJohn,

Start a new post that way it will be easy to find,

Guido.

Or just post in modern view. The thread will remain on page one as long as there is activity on it.
