    Battery Maintainers

    Despite what George thinks, there is no AC. Use a good meter and there will be no AC. I put a scope on my BatteryMinder a few days ago and there was nothing but pulsed DC and only a few volts over the battery voltage. No high voltage, no AC. This agrees with the BatteryMinder web site. Just low...

    Shocking a battery

    Mark, I agree the average meter, analog or digital, is not going to read a short pulse like what I would expect on a desulfinator so I have trouble George's meter is giving the information He thinks it is. My Fluke has a blocking capacitor which is why it reads zero when measuring DC on...

    Shocking a battery

    You missed the point of my post. The error on the HF meter and my Triplet and Speco meters is absolutely due to 1/2 wave rectification. The Triplett and Simpson both use 2 diodes arranged as two legs of a Wheatstone bridge, the other legs are calibration resistors. I assume that arrangment is to...

    Shocking a battery

    None of the theories I have read nor any of the circuits I have seen use AC voltage/current for desulfination. They all use pulse DC. I put one of my desulfinators on a scope when I first got it years ago to see what the output looked like. It was DC with a short higher voltage pulse although I...

    How long does a Tank Of Argone Gas last?

    A common flow rate is 20 cf/hr so a 125 cf tank would last a maximum of 6.25 hours. Leakage, set up time, flow meter errors, etc will reduce that ideal time. Argon if welding aluminum, C25 mix for mild steel.

    farmall coil

    Not all names or terms make sense in strict reading. Hot water heater vs water heater, both are commonly used and both are correct and both are easily understood as to the meaning although some will swear that "hot water heater" is not technically correct and therefore should not be used. The...

    more discussion on Earthmaster models

    Earthmaster wheel weights: Part number rear 54751, front 54721, which are cast into the weights. The weights came standard with the C and D models so they would have been Earthmaster weights. This post was edited by electro on 12/30/2021 at 05:07 pm.

    more discussion on Earthmaster models

    The 9 x 24 tire will not help you tell between a C and a D. The CA tractors had 9 x 24 tires either as standard or as an option. The NC tractors had 9 x 24 tires standard. The wide axles were only on the D series of tractors. The 9 x 24 tire eliminates the DH and the DXH so you have a model D...

    Earthmaster color

    The colors changed depending on where it was made. The California tractors were red with galvanized wheels and chrome lights. The hood decals were small and white. The NC tractors varied from red with yellow grills and seat or red with yellow grills, seat, fenders, and wheels. The lights...

    John Deere H Restoration Book

    I ordered one a few years ago and had it printed and bound since I prefer a hard copy. Try this link for the ordering info: https://forums.yesterdaystractors.com/viewtopic.php?t=1453589

    Differences between Earthmaster C andD

    The wheels will adjust to 64 inches max on a C and 84 inches on a D.

    Alternator on a cub

    You may have a one wire alternator. Pull the plug and look. Are the two spade terminals connected with a jumper that is part of the spade terminals similar to what you would see on a household duplex outlet? You could also take the back off the alternator and post a photo of the regulator. A one...

    Electric motor wiring

    Until the OP gets back with more information it is all just guessing. I believe this motor was part of a whole dedicated setup and the label reflects two parts of the needed setup information. Under the section labeled "115 volt connection" is the information needed to wire the far end of the...

    Electric motor wiring

    Not so fast in thanking me. The wiring terminal numbers I posted is correct, however, I do not think the terminal numbers correspond to the wire colors I posted. I do not believe the terminal numbers on that motor are standard. Normally there would be 1,4 as the run windings and 5,8 as the...

    Electric motor wiring

    1 and 4 are the ends of one winding. 2,3 are the ends of the other winding.
