Ammeter on 8N

[wallywoodcutter]

The ammeter on my recently purchased 8n doesn't move. When checking the wiring I couldn't find where the wires were connected to the gauge, only a loop where the wire passes through. Can anyone shed some light on how this works? I don't know if it is OEM as the bezel is chrome, but the OEM oil pressure gauge is black.

Looks exactly like the one that was on my 8N when I got it. It also didn't move but I'm guessing that was because of the rust inside.

It's an oem induction type ammeter. Non-working ones are pretty common.

Keep in mind that the ammeter could be working fine and you have a problem in the charging circuit.

Induction amp meter - original. Run a magnet around the face. If the needle moves it may be OK or can be repaired. If the needle doesn't move
when a magnet is near, replace it.

You guys are brilliant! I ran a magnet around the face and the needle stayed in the same position. New ammeter is on the way. Thank you for your help!

Just beware, the new one will have two terminals, not the induction loop.

Yes, I am aware of the two terminal type. I bought a 1949 8N three months ago that was supposedly "restored". The generator was bad so I converted it to 12 volts and rewired the entire tractor. It has several other problems, so when I came across another '49 that was in the same family since new, I bought it. My "restored" looks better than the newer one, but the newer has better hydraulics and better mechanical. I knew nothing about 8N's when I bought the first one, but boy I learned fast! The old man I bought it from found a sucker, but I am not unhappy because It has kept me busy the past several months. And....now I am an 8N fan at 78 years old.

I have been following this thread! I am rewiring a '49 front mount 6 volt system. My new ammeter has the two posts. I have a connection for one post! But what goes on the other??? I bought a wiring harness from Steiner. When I took out the old one it was not hooked up at all - no wires going to the old one. I do have the large wire (Yellow) that connects to the Solenoid terminal. What would go to the other ammeter terminal??? Thanks for any advice!

Pitch the amp meter and put a voltmeter in that hole. : ) life will be good...

I am sure a amp meter lubber with haft a brain will come along and confuse the other haft of his brain trying to WOOOOO us.

A 12V system has no need for a Dinky amp meter NONE!
