I have a 51 H that had a good battery last summer (all the connections still shiney- no corrosion) but over the winter has died. It won't even turn over the motor once. I have a "manual" trickle-charger. The 6V battery is still hooked up to the H. Do I just hook it up like a car ++ -- or not? I think I heard that there is another correct method to recharge an H battery without removing it from the tractor OTHER than how I mentioned. Also how long to leave the trickle charger on? Thank you.

If you are lucky enough to have the amp hour rating of the battery, like 75 amp hours or so and your charger charges 5 amps, it should charge fully in 15 hours. If charger is 7.5 amps then time is reduced to 10 hours. Just a nominal rule of thumb, may vary a lot. Hydrometer is even better, but you have to have removable covers.

IF the battery will hold a charge my next step is to figure out why it instantly floods when starting (sort of had a little to do with why the battery died- too many starting attempts). My guess is fuel shut off is not shuting off- why? because the bent metal screw "open" "close" doesn't seem to close? Or something as simple as an old float? Either way- need to get parts catalog and look inside the carb to see what it looks like- maybe it needs rebuilt?

It sure sounds like your needle valve/seat/float is misbehaving, all right. This is also pretty common after a vehicle sits for several months.

The gasoline leaves varnish or other deposits on the valve/seat, and leaks develop.

I run my Super C quite a bit and the only time I"ve had the carb go bad on it was while the tractor sat idle for several months while a better machinist than I re-sleeved and -pistoned the motor about seven years ago.

I bought a new carb. When it"s starts to go, I"ll have the original rebuilt. As I understand it, there"s no point in having it rebuilt now because hopefully the new carb will last several years, and by then the rebuild will have gone bad.

I"ve never seen a leaky float, but others certainly have. Even so, I think it"s more likely to be the valve/seat themselves, or maybe a STUCK float.

Henry - If the tractor runs OK once it starts, flooding while cranking comes from using too much choke.

Unless it's below about 60 deg, a properly adjusted H will generally start with no choke whatsover. Of if it does need choking just a quick pull and return of the choke rod while the engine is being cranked will get it going.

Now if the carburetor drips with the engine STOPPED that's a different story! Something's wrong with the float or float needle valve - time to go inside the carb for a look.

Incidentally the shutoff valve at the sediment bulb should be used only to shut off the fuel when putting the tractor away, or to remove/clean the sediment bulb. And even the shutoff does leak it will not cause flooding, etc of the carburetor.

I've tried the zero-little choke start (an old farmer told me that when I bought it and I've always considered myself conservative wih the choke when starting but thanks for the tip : ) Yeah, it starts to drip gas immediately from the carb when trying to start (with zero choke)- which is why I think that the fuel shut off is not shutting off and maybe it is already flooded before I even start it? There is no leak at the sediment bowl or line or anywhere else. Thanks for your tips though, I'm sort of a newbee with no mechanical ability.

OK Henry I agree - the carb's probably flooded before you even begin to start. That indeed indicates a slow leak at the carb float needle valve.

Would be worthwhile at this point to buy /install a carb rebuild kit. (Make sure the kit included a new float needle valve and seat).

Fortunately the H carb is pretty simple and easy to rebuild.

Thanks Bob M. Need the proper manual and I guess the parts catalog is very useful in its diagrams. My dad thought the H carb was similiar to a Model A... he has some experience with those.

You may need a new battery. Read on...

I just hook up the battery charger, red cable to positive and black cable to negative. Which terminal is grounded makes no difference; it is the polarity of the cables and battery terminals that dictate how they are connected.

As to how long to leave it charged; ideally you would leave it hooked up until the voltage differential between the charger's circuitry and the battery's terminals was gone and there was zero current flow.

Always remember the twelefth of Novem...wait, that's Guy Fawkes' Day. I'll try again.

Always remember, I=E/R (Ohm's Law). In this case, I represents current flow, E is the voltage differential, and R is the combined resistance of the cables and connections. I think the battery's internal resistance also plays a role, but I can't positively recall at this time.

So, if E=0, I must equal zero in a fully charged battery. If your charger has no built-in meter, you can connect a VOM ("AGAIN with the VOM! This 'Bohemian' guy and his VOMs...") as an ammeter and monitor the state of charge untill current flow drops to zero.

However, this is the ideal situation. In fact, I find the battery perfectly satisfactorily charge when the current flow has dropped to %20 or less of the maximum current the unit can supply (NOT the initial current in any given charging application).

In other words, with my 6 volt 6 amp charger, I consider the battery ready to go when the current flow reaches about 1.2 amps.

I note you are usinig a trickle charger. I am not familiar with these but believe 2 amps is a typical maximum charge rate. It will probably take SEVERAL DAYS to see the charge rate drop to .4 amps, but I will defer to anyone with more experience on that particular matter.

Finally, in my experience, batteries that were seemingly fine four or five months ago but that are mysteriously dead have a high failure rate. Some fail to take a charge; most will fail to hold one.

Check for voltage with a VOM ("AGAIN!"). You should have two or three volts. Less than that and the prognosis is grim. If you have absolutely zero volts, the battery may have a dead cell and not take a charge. A flickering meter means the battery has developed internal "noise," but I've only seen this once with an automotive/tractor battery.

At your convenience, please post back and let us know what you end up doing.

Double check first to make sure the battery is really dead flat - stick a voltmeter or a 6 volt test light across the battery posts. (Sometimes corrosion/open circuit will occur at a cable ground or starter switch connection during a long idle period which mimics a dead battery.)

Presuming you find the battery is truly "dead", first check the battery electrolyte level. If you find any cell way down, it indicates the battery froze, cracking the case and draining the cell. Time then for a new battery(!)

However if all 3 cells are OK, stick your trickle charger on it(charger + to battery +, and - to -) then plug it in.

If the battery is OK the trickle charger will bring it up sufficiently to start the engine after about 24 hours. However if it does NOT figure again on a new battery.

Do it just like a car. Use both clips to the battery to avoid the difference between pos or neg ground. pos to pos, neg to neg. Length of time depends on the charger. Use a meter to determine if the battery ok. some batteries that get that low will never recharge.

You can tell from the battery's electrolyte the
state of charge by measuring the electrolyte with a hydrometer. It should read around 1.250 and each cell reading should be close to one another.
I would do this after the battery has been charged. Hal
