12 volt cut out

Does anyone have a 12 volt mechanical cut out for a early Delco Remy 12 volt generator. Have electronic cut out and having problems with it.

Any 12 volt regulator will work. Just use the two terminals only. One marked batt and other marked gen. Ninety nine times out of a hundred, the cutout relay is fine on a replaced regulator, it is the voltage and current units that are bad.

Another option is to take what you have apart and solder in a single bridge diode out of an alternator. Band facing the battery. Jim

This is a new electronic cut out got it last year, 2 terminal. It's on one of the mds. Keeps over charging battery.

Over charging is not the fault of the cut-out. Generator field is grounded somewhere.

How should the cutour be hooked up. Wiring harness is for a 3 terminal cutout and cutout is 2 terminal. Haven't been able to find Alot of info.

The cutout might be just fine (as noted) the regulation of the charging rate is cone with a field resistor to ground often found under the three terminal cutout. The second way is to use a Charge selector knob (often on the light switch that selects between low charge for continuous operation in daylight, or high charge (grounded field) for recharging if stopped and started often, or winter use for a half hour. The light switch also keeps it on High charge to keep up with the light draw.
The charge rate is often set for these methods using a third brush on the generator. This brush picks up voltage from the gen's commutator, and is adjustable by moving the brush physically closer to, or farther from the fixed brush on that side of the commutator. If yours is set for a grounded field, using the third brush adjustment to get about 13.8 volts (if the battery is charged setting the current to about 2 to 3 amps charge lights off)
A real voltage regulator with 3 terminals will regulate the charging rate automatically from makeup fast charge to maintain charge when running for a while. If the full regulator is used, the third brush should be set as close to max as possible. Jim

Bob M or Janicholson can correct me if Im wrong, but here are my thoughts:

The "Cutout Relay" 2 terminal BAT and GEN is for the older 3 brush generators and was used instead of the later 3 terminal full fledged BAT ARM FLD (maybe LOAD also) Voltage Regulators. HOWEVER since that 2 terminal cutout (if/did IHC make one???) didn't have a FLD terminal, the gennys FLD connected instead to the LHDB light switch which supplied a ground for the gennys Field and regulated for manual LOW or HIGH charge rate.

ALSO for older tractors without lights and no need for LHDB light switches to regulate charge rate, they made a Cutout Relay with the normal 2 terminals BAT and GEN PLUS it had a FLD terminal to connect to gennys FLD post. HOWEVER it did not self regulate charge rate like LOW HIGH manual switch or a Voltage Regulator, it was just a fixed resistor to ground.

If the wiring harness is for the older cutout relay which had the fixed FLD terminal but you now have a VR or a LHDB light switch, don't wire anything to the cutouts F (ignore it) but connect the gennys FLD post instead to the gen/fld terminal on a LHDB light switch. If you had a VR (BAT ARM FLD) the gennys FLD post wires to FLD on a VR.

I agree with Teddy, if its overcharging its because the gennys FLD must be somehow always dead grounded and never can be set for LOW charge (like from a LHDB light switch) which has some resistance (maybe 2 to 4 ohms) to ground
