Hi guys

 

The only way I was able to make both ammeter posts show hot was to wire it this way?? Ammeter shows a slight discharge when key on. I have cranked but not started it yet,too cold here. I guess my question is hot battery plus post is on the right,load is on the left as viewed from tractor front under the hood.  On the gauge viewed  from driver position,discharge side of ammeter is connected to the plus side of the start solenoid,charge side of the ammeter is connected to the ignition key switch  and the "B" terminal of the voltage regulator.  This is the opposite of what I would of expected.  Anyone with insight or a picture of their working tractor wire setup would be appreciated.  Thanks much!! I removed two wires the previous owner had installed that weren't in any pictures or supporting documents I had.

 

I found this page to be useful for installing ammeters in start/gen setups

The wire that runs from the ammeter to the turn key switch I don't believe that it's on mine but I'll check tonight.

Are the wires on the same posts though?  My documents say load post of ammeter goes to "B" terminal on voltage regulator ,and ignition switch, other post on ammeter goes to plus side of solenoid.  I have checked the wires from the gen "A" post...goes  to minus term of solenoid,and GND of voltage regulator.  "F" post on generator goes to "F" on voltage regulator..  Thanks much.  A picture would help..If its the original wiring bundle,it would not help as much since that is missing on mine..Thanks

I am going to have to study the pics awhile.  I notice you have a 3 prong ignition switch  vs my 2.  The positive and negative cables to the start button are swapped too.  What is the black plastic switch by the choke lever??Light switch??

Additionally the black wire from the Generator "A" post is very thick(almost like the red one).  I may need to get a new black wire too.

Why not find a Wiring diagram for your tractor or similar model??  I'm thinking Plus from batt also goes to plus on guage if marked. Some are not. Even if main wires backwards, the guage still works, just backwards??  If you have draw setting still, must be wrong somewhere.  Wiring diagram, follow one path at a time.

I have  been looking for a diagram for months. Unsuccessfully.  I have found some schematics that show wiring harnesses,but not detailed enough.. This troubleshooting paper said there should be a slight negative  draw when just ignition on.  It applies to a farmall cub with a delco -remy starter/generator.  I think it shoud be very similiar to the chief ,which also has a delco starter/gen.

This diagram is from a cadet 102. Similiar to my 66 chief,except I have a start button instead of a key.

Vintage,

 

Thanks for all your help and pictures.. I started and ran the tractor for 15 min this morning.  Ammeter had slight discharge just with the key, pushed start button till start and ammeter showed about 9-10 for about 15 seconds and then settled down to just positive.  I think it is working fine and charging.  I still would appreciate the diagram if you have it so I could add it to my downloaded manual.  Thanks again!
