Charging Problem 230 farmall

Restoring a 230 Farmall. It has a generator, 12 volt negative ground regulator. Had new wiring run on tractor with new gauages. Ran diagram as was shown in the 230 operators manual. Should the wiring for the 12 volt be any different than the 16 volt. Does not show charging. Polarized generator but still no charging. Any help would be most appreciated. Thanks Diana
 
Did you 'flash' the regulator? Every thing else would be the same, also you are now probably running a negative ground, not a positive one like the original 6v had.

Hi Andrew. Yes he said it was on a negative ground. Not familiar with "flash" the regulator. What would that consist of. I know he polarized the generator. Thanks
 
Diana, This is a quote from Bob M, he knows far more about electrical then I

"...With all the wiring and the battery connected, and with the motor shut down, take a short piece of wire and use it to jumper the BAT and GEN terminals at the cutout or regulator. Only leave the jumper in place for a moment - soon as you see a spark the generator's been polarized..."

Hope this helps

Andrew
 
"Flash the regulator" is a cutesy-wootsey term used by folks that don't realize that they are actually polarizing the GENERATOR. (Even though they may be making the momentary connection at the regulator.)

Siece this is an "A" circuit system, verify he momentarily jumpered the "BATT" and "ARM" terminals. ("ARM" is labeled "GEN" on some regulators.)
 
He has already done this. It is still not charging. Should any of the wires be any different. I noticed that on top of the generator the F and A terminal are in opposite locations as shown in the wiring diagram in the operators manual. The F terminal is to the front on the generator and the A terminal is on the back. Would this make any difference. The wire was hooked up on the terminal the directions called for.
 
F regulator to F on generator
A or G on regulator to A on generator
BAT on regulator to ammeter
L on regulator (if used) to light and ignition switches

To test generator/ regulator:

If you have a volt meter, check battery voltage with engine off. Start engine and bettery voltage should increase at least 10%. if not

With engine running, ground F on generator. If charge increases suspect defective regulator section in the regulator or associated wiring/grounds.

If still no increase, leave F grounded and jumper A on generator to BAT on regulator. If charge increases suspect cut out side of regulator. If still no increase in charge suspect generator/wiring/loose belt.



Charging circuit will wire the same on 6 or 12 volt.

Ignition circuit with 12 volt will require an additional resistor in the wire between switch and coil or a "12 volt No External Resistor Required" coil
 
The F terminal is smaller than the A terminal.
To test output:
With the tractor running at 2/3 throttle, and every thing connected as the diagram indicates, watch the amp gauge and use a jumper (piece of solid copper wire with insulation removed 1/2" on each end) to ground the F terminal to a good ground (shiny metal) this will not hurt anything. If it charges, it may need to either have the VR grounded better than it is, or a new regulator. Jim
 
what you need is to follow the super-duper U L approved charging system checker out-er directions by our very own young and handsome John T, the electron wizard. just click on the link and follow the instructions start to finish.

Has the regulator been changed to 12-volts? If it has & the generator to regulator wires are correct, ground the regulator frame to battery negative post with a jumper wire. With another jumper wire, connect it between the battery positive post & the BAT terminal on the regulator. This will by-pass any wiring problems. If possible, use an ammeter in your jumper wire to read current flow. If this test doesn't show any results, the regulator could be suspect.
 
Thanks Guys for all your responses. Found the charging problem. The generator was turning counter clock wise and my tractor runs clock wise. Got another generator and the tractor is now charging. Thanks Again. Diana
