Ammeter gauge

[Karnack8N]

I?m looking to replace the ammeter gauge on my 6 volts tractor not should what?s the correct reading it?s around 20 on the negative side

Karnack,It sounds like your generator is not charging your battery.You need to Check the voltage at the battery with it running with a volt meter.It should reed 6.9-7.5 volts if it is charging.

you sure the wires are not backwards ?

hat is funny! Dentist says that the tooth you complain about hurting has a cavity and you decide that you need to replace the dentist?? Go figure! :roll:

AMMETER doesn't have polarity necessarily, not an active device, are not set 6V or 12V as they read AMPS not VOLTS. Gauge reads NEG to POS for charging. N's used a 30/30 Induction (LOOP) style ammeter. If gauge is reading backwards, the wires are crossed so simply reverse the screw terminals and feed the loop thru the other way. If gauge has no reading at all, before you go and buy a new one, try a different gauge if possible, but I agree with Den that chances are your generator and wiring are all mucked up. Is the generator properly set for belt tension? There are tensioner devices on the 9N and 2N and a bar device on the 8N for belt tension. Without tension the generator will just slip and will not charge. Check the belt tension first. If tension is set properly, the next step is to verify generator is motoring. Procedure is in the I&T FO4 manual for that. Option #2 is to remove the generator, ammeter, cutout or Voltage Regulator and take to your trusty starter/alternator shop who knows Ford Tractors to be tested. Always do a true root cause problem solving procedure for any problem before going and tossing money into parts you may or may not need.

Thanks for the information , it does have the loop ammeter will try redirecting it and clean it up

 

[Karnack8N]

I?m not sure was able to find a wire digram will check it up
Thanks

 

[Karnack8N]

Thanks good to know

Do you know what is going to happen if your system is discharging and you reverse the routing of the loop? The ammeter will show a charge. So how will you know if that is right or wrong?

Get a $10 volt meter and do a little basic diagnosis of the charging system and forget messing with the meter. Check battery voltage with the tractor off and then again after starting. The two values will tell you if the system is charging or discharging.

I have one question. It measures amperage right? So why is it not called an ampmeter?

Why is an altitude meter called an altimeter and not altitudemeter? Because it is. That a good enough answer?

When I worked in a small aircraft job shop, my boss (owner) having all kinds of salvaged equipment including a whole H86, had an altimeter in his car. He called it his uppety gauge.

About the ammeter, one simple little P is missing. That is just plain stupid or laziness. I can just picture the guys who designed that ammeter. One guy says "what are we gonna call it" another says "an ampmeter", another genius says "no, that's too long, lets take out the P". Thus ammeter.

Dam lazy a$$ German engineers. Herr Drexler was even stupider and lazier than you imagine. The instrument measures current flow in "amperes" so he actually left out four (or should that be five???) letters.

Or we could simply say that someone other than Caryc had naming rights! :lol:

It is the same as many other things. Like starting every sentence with the word "so". Fifteen years ago nobody did it, now I am the only one who doesn't.

Ammeter should be 20/20

 

[Caryc]

If one wants to really get technical about it, I guess it's not even a gauge. It's a meter. It even tells you that in its name.

How technical do you want to get?

gauge
/j/

noun
1.
an instrument or device for measuring the magnitude, amount, or contents of something, typically with a visual display of such information.

I really have no idea what measures "ams"??????????????????

You'd have liked an older neighbor of mine who pronounced it something like "amateur gaj"! :shock:

Keep digging. You are making the hole deeper than it needed to be.
