Decided to give the old Marquette a look today. I'm constantly amazed at the simplicity of the design and quality of the components that went into these old machines. There is no comparison with today's machines!! Modern technology may be able to provide more functions at a lower cost, BUT just looking at these 50 year old components says a lot about how American manufacturers felt about lasting quality. These thing were expensive, so they built them to last!! -- Amazing ---

It's a bit beat up, but very salvageable!!





Look at that massive transformer!!!!!



Hooked it up to a battery and it started chargin'



Time to strip this charger and take inventory!











Cables and silicon rectifiers are MASSIVE -- this is truely "old school"



Working slowly form the top, I strip the components with the wiring harness attached -- makes it easier to clean and inventory the parts





The fan motor was the first item to get removed, cleaned, and lubed.



The oil hole was filled with some 30W non detergent and the motor spun like new. The motor and fan were cleaned and are ready to be reinstalled.





The transformer was next -- This thing is heavy.









Some new wires will be required -- there is rodent damage, but that's not a "show stopper"



Everything is removed from the carriage --



The carriage is cleaned, sanded and prepped for paint





Cables and clamps will get cleaned and refitted with new connectors. the wheels will get media blasted and painted gold.





First task is to strip the ammeter and clean/paint the rusted housing -- Before and After









The bezel plates were trashed and corroded. They're aluminum, so they are pitted and oxidized. The plates came out OK with a good dose of lacquer thinner --
They cleaned up well enough to make the project respectable again.





Last thing for today -- the carriage was prepped and received it's first two coats of paint. That will get sanded with 220 grit tomorrow and one more coat of paint will be layed on wet.





That's it for today -- time for an adult beverage  :Peace:

Good night guys!!

OK, let's finish this thing up!! I'm sick of looking at it!!  :lollol:-- Not really, but I did bust hump to get it done today. It was a challenge since it's damp and rainy outside; which makes paint almost impossible to cure -- but I managed.

First thing today was the front cover. After sanding I masked the decals off with tape and proceeded to cut the lettering and outlines with a razor blade











I then turned it over and shot the red basecoat. I also shot he final red coat on the carriage (after it was sanded with 220 grit)





While I was in a masking mood, I decided to sand and mask the control cover -- the masking was for the instruction decal on the inside





This is the gold color I finally settled on -- not perfect, but when it dries it's pretty darn close





The front cover "red" basecoat had dried enough by now so I shot the the gold half-tone on the front -- looks really good, this paint covers and dries fast.



While all the paint was drying, I switched back to reassembly -- I cleaned the switches and wires with WD-40 and replaced two wires that had been chewed on by some critter.

I put down clean towels and started to get all the guts back in the carriage



Good pics and some simple schematics and notes help make this job go quite quicky





Cords and cables were cleaned with my "patented" lacquer thinner wipe down, and then cleaned again with WD-40. This makes them shine like new!!
The clamps were also given a good wire wheel treatment and the look like new. Tough stuff these old clamps.









The bezel and switches were reinstalled in reverse order of removal (I write down the sequence of removal on a note pad)



The 110v electrical connection for the fan and the accessories were made next



The charging cables were reconnected to the rectifiers in proper order -- and the charger was pretty much done with the electrical hookups



Next came the wheels. I found that a quick way to paint wheels is to cover them entirely with packaging tape (it's easier to trim and cut with a razor) and then just cut out the center hub for spraying.
This sure beats trying to mask the rim first. It only takes 2 minutes to mask a wheel this way.









Pretty much done -- except for the handle; which was shot in gold as well





OK!! Here's the finished product!!!

BEFORE!!!





AFTER!!!













Believe me guys -- this will be no "shop queen" -- it'll get used "like I stole it". So take a good look. In three months it'll be somewhat scratched up and quite dirty like most of my tools   :lollol:

I'm beat -- these two day resto marathons are gettin' a little tiring :toothy9:  Time for an adult beverage!  :party:

Did you load test the charger before you tore into it?

I've come across a few chargers that the transformer was not delivering sufficient voltage after many years of hard charging.  The guys in the lifttruck shops tell me it is a common situation.  I listened to an EE explain how it is a function of magnetic saturation of the core over time, and after an hour of his droning decided it is just easier to load test and decide to scrap of rebuild.

Fortunately the ones that come up short are still fine for electro-cleaning and rust removal.

beautiful job ! I have a model 32-106 that's almost identical. I am also going to restore it. I am looking for an amp gauge. also the fan quit working. any idea of how to check it ? I don't know what volt it is. I'm very challenged when it comes to battery chargers.

That model is most lilely early to mid 1960's -- but I'm not 100% certain since not a lot of information exists on these units.

The fan is energized by the unit's on/off switch and draws standard 110v current. Just unhook it and run a temporary power cord to it. I use an old PC power cord and cut the end off. I soldered on some insulated alligator clips the hot, neutral and ground leads so that I can energize and test my 110v components (careful though, you don't want to touch those leads when you plug into an outlet -- even though they are insulated, you can still shock yourself).

Hi there. I realize that this a few months old but if you are still looking for the wiring diagram.....I just finished rebuilding my BC 322N Redi Fast charger and could draw one for you.

Goodfellow, thanks for posting this. your pics have helped me a lot. I got a 321s model a while back and am now getting around to looking at it. someone took out the silicon diodes and the piece that they were attached to out before I got hold of it. Does your diodes have any info on them? Thanks in advance for any info!!! :thankyou:

I opened up the charger to see if ther were any identifiable markings on those diodes. Unfortunately, due to age, there is nothing left that I can find to suggest what values are involved. That said, I would think that a modern bridge rectifier that could handle 50 or 60 amps would be good enough for one of these old chargers.

Thanks for the ree-ply goodfellow. I have a line on the rectifier diodes of the same design. So all I have to do is to fab up the bus bar and insulators/mount. Here's a couple of pics of mine. Guess I am  going to have to fix mine up too!! Maybe a build thread?

OK. Got my Diode situation squared away. Put in a 30V 500A , I believe they call it a Schottky. It has a buss bar output and 2 threaded inputs. Bolted everything together and I have power!!I had to re arrange some wires, but it appears everything (except the little green light) is working. Guess I will have to do a build thread of sorts. Only thing I won't be able to do is a full repaint. The front is stenciled an I have no way, and I don't think I have the patience to mask and trim it. Only problem (maybe) is the rectifier on the solenoid. I think it might be bad. Will do some more testing. Next post, build thread!! :cartangrys:

Looks like there's another one on ebay. This is only the third Redi-Fast charger of this type that I have seen on ebay in 10 years. They were popular in the day, but they were also beat to hell in professional shops.

Since they cost so much new, they were rarely purchased by home hobbyists --

http://www.ebay.com/itm/Vintage-Marquette-Redi-Fast-Battery-Charger-/270812977104?pt=LH_DefaultDomain_0&hash=item3f0db617d0

It's seems in reasonable shape, and could be a candidate for a good restoration if someone was interested

Hello everyone. My name is Jason.  I have a vintage Marquette Ready Fast 6v/12v charger that is identical to the one the OP restored.  It was my dads. I was going to get rid of it, as I don't use it, nor do I know how to restore it.  Is it worth anything?  I'd rather see someone buy it than to throw it to the curb for scrap. It worked last time I used it. But that was about 3 years ago. Attached are some pictures.  Thanks for any info you can provide!

-Jason

Welcome Jason --

Why get rid of it? If it's still working just clean it up a bit; a little sandpaper and spray paint here and there and you have a great machine that most folks would envy. Modern chargers have nothing on these old "battleships". They were meant to last, and with a little effort on your part, this charger can be a great conversation piece in any garage.

If your bent on selling it, then just clean it up with some soap and water, and hit the heavy stains with Simple Green. You could get up to $100 for it if the right person comes along.

Hey! Thanks for the welcome!  For the heck of it, I plugged the charger in and tested it on a marine battery. The ammeter dosent seem to be functioning... unless it's a bad battery perhaps?  I do get a readin on my new charger that I have....

I wouldn't have a clue how to fix it... any ideas?

Chances are that the only problem you have are some bad wires. I know mine did. If you're handy with a continuity tester or an Ohm-meter then you can chase those problems down pretty quick. The biggest issue I had with mine was rodent damage on the wires, and corrosion of terminals.

Sorry -- no schematics are available for machines that are this old. Marquette isn't in business anymore, and those machines went off the market in the late 60's --early 70's.

I too have a Marquette charger. The timer doesn't work on mind. Anyone have a picture of the inside of the timer or know of a compatible timer device that can be used?  I have not yet opened mine up to see if it is a simple matter of power to the motor inside the timer's clock, so a picture of what it should look like would help.

I see a mention of uploading a wiring diagram but I don't see it.  Not sure if I need to do something more to see it?

This post inspires me to have mine repainted, and make it dirty afterward.

I'm open to suggestions for what to do to make up a green bulb cover for after I make the bulb work again.  Really I have no problem using it as is, with less than perfect wires and no timer.

This thread is very old -- I'm sorry, but no one ever found a wiring diagram for this unit. Info is very hard to come by because they were phased out so many decades ago. As far as the timer is concerned, they are very simple units and you will most likely find that a simple spring is broken, or it lack lubrication. I many cases the fix is quite simple.

Take it apart and have a look --
