Default US Army Ordnance Battery Charger (12V Generator)

Found this little beauty at the scrap yard today (its amazing what people sell for scrap). Tag reads US Army Ordnance, Battery charger, portable gasoline engine driven, 12 volts 133 amps 2000 watts, continuos duty 2350 rpm,, operating weight 240 lbs, manfactred by Pioneer Gen-E-motor corp, Chicago Illinois, model BG20L, serial# 2458, date 6-30-51, looks like theres a little more, but I need glasses to read print that small.

Engine is Briggs & Stratton, engine model 23FBP, type 203567, serial#145416

The electrical panel has plugs labeled 6V & 12V, under cover is an amperage meter and a knob to decrease/increase amperage.

What would this have been used for? Charging batterys for tanks, radios, turret guns, radar sites, missles

I think your engine is from Sept, '52. Got this from the ASECC data pages, but they don't mention a 23F, so I went back to the original 23 and came up with this date.
Is that a fuel pump on the back side of the engine?
Great find!

Neat outfit! I like the Nelson muffler! With that muffler, you probably will hear more mechanical noise from the engine than exhaust noise from the muffler!

I have the parts book for the 23FBP. The "F" means Flange Mount, The "B" means Ball type main bearing. There may be only one between the engine and the generator or it may have ball bearing for both main bearings. The "P" means Fuel Pump.
Check www.then-now.com or call 781-335-1579. This company build fuel pump kits with modern material that can handle what we have that is called gasoline today. If you have running problem with the engine as you throttle it up, you will think you have a carb problem. It is NOT a carb. problem! It IS a problem with a bad magneto coil. Coil, P/N 290880 is NO Longer Available from Briggs. I have designed a coil conversion for this engine. The info was published in the Nov. 2005 issue of Gas Engine Magazine. I found out recently that the article is posted on GEM's website. Search the articles title " Cheap Fix ". You CAN NOT eliminate the engine points with one of the universal electronic ignition kit for small engine BECAUSE this engine has a ignition advance mechanism on the camshaft. If you try, when you go to start the engine, it WILL jerk the rope from your hand as it will fire early. I also found out recently that all Briggs engine before the Five and Six digit model number use a plug gap of .025 inch. NOT .030. This engine is .025 inch. Point gap is .020 inch. I collect these engine. I have a full set of the Numerical series that run. I do not have any generator but I have two that are Protable Fire service water pumps.

I forgot to mention I like the MILITARY GAL telling the men to keep the engine cool. The military used the same caricature on the care manual for the M-16's when they had the jamming problem on the weapon during it's first used in Southeast Asia.

Thanks Redd, great info to know. Not sure when I'll get around to fixing this one, there are already 2 engines I'm working on, and I have my big surfacing machine torn apart at the moment, so I'm full up on projects. This engine turns over very smoothly, theres just no compression, but I'd bet its just junk in the valves.

So no guesses on where this genny was used? I've seen lots of military generators, this is the first I've seen with an U.S. Army Ordnance tag, any suggestions on how to find its military application?

Exhaust valve is likely stuck.

Back in the 60's the M-75 armored personnel carriers had lotsa radios--big ole radios-with filaments in the tubes---drew lotsa watts--when you parked that thing, 1st order was to hookup the battery charger to keep from runnin the batteries down---that big old 6 cyl opposed air cooled Continental made too much noise & used too much fuel to keep runnin.

I have two of these one just like yours and one with a 2 cyl onan engine also have the funny looking cable to connect the charger to the batterys. On my unit the control knob next to the amp meter adjust the voltage. I hook it to a dead optima battery a turned the knob all the way up the voltage increased to 16 volts. I had to rebuild the engine on the onan powered one which was fun since no parts can be found. I had to make my own crank shaft bearings by turning them on a lathe out of a 5 inch dia. chunk of babbitt. My Briggs powered unit needs to be rebuilt also as it is stuck from setting out in the weather.

hi Joseph,
I/we have one of these same Battery Chargers (with a B&S engine) sitting in our garage (except it doesn't have the "Keep this Engine Cool" gal on it! It hasn't moved for some years and I have no idea if it works or not - belonged to my partner's dad. I need to free up some space - don't suppose you can suggest a way to find a good home for it and any idea how much I should ask? We are in Louisville, KY. thanks

Cinnamon I have no idea what a fair price would be as far as finding it a good home I would try the classifieds on this site.

I have one of these same chargers but it needs to go to free up garage space. Can anyone suggest a value or a good way to sell?

Ref parts list for this 23FBP generator that K D included in his discussions herein... does anyone have a copy of the parts list that I can download? I just purchased the same 12V generator for $27 at a nearby auction in Omaha... didn't realize it was a 12 V until after I raised my paddle (after I had the chance to look it over)... engine runs well, as it was maintained by the Corps of Engineers.. but what am I going to do with a 240 lb 12 V generator... convert it over to a 15 kw or so ac alternator possibly?... anyone have any ideas? My first post!

Nice, Dalmation - fix 'er up, put wheels on cart, and when your fork lift or crane battery goes dead, you can quickly charge it wherever it is - no need to drag back to electricity.

I still have it, and its still on the "to do" list, maybe this fall when I'm on vacation. I was thinking it would be a great battery charger for my off-grid cabin, another project on the to-do list
