Need to know how to wire koler command voltage regulator

I am unfamiliar with the model but ignition wiring is almost universal and on a negative earth system a supply from the ignition switch is connected to the positive (+) terminal of the coil, that in earlier times was marked Batt.
The other coil terminal is connected to the contact breaker or ignition amplifier or cdi as applicable...

The link below should provide a downloadable manual.

Wiring diagram can be downloaded from equipment manufacturer , ie, mower , or tractor builder . Also check Kohler small engines online ...

Without a model number for the machine itself, you are screwed. By looking at your pictures you might as well take out all the wiring and start over from scratch if you want to keep this machine.

check for muck in the carby bowl tending to block the main jet.

Duplicated previous question HERE.

If no damaged wiring is found, it's most likely an internal fault in the ECM (Engine control module, computer, PCM, ECU, whatever you want to call it, it goes by many names)
The Voltage Regulator is built into the ECM on virtually every Chrysler product (including Jeeps) after 1987 or so. And it is prone to failure. If it does fail, you either have to replace the ECM or install an External Chrysler Voltage Regulator, which requires some wiring harness modifications and a few parts that can be purchased at your favorite auto parts store.
To do the External conversion, you'll need :
1 Chrysler Voltage Regulator (virtually any Dodge/Plymouth from 1970 - 1986. It's best to order one for a 70's 4x4 Truck with a 318 engine though, to avoid any possible mix ups)
1 Chrysler Voltage Regulator Pigtail (this is the plug that connects to the regulator)
Roughly 10 feet of 14 gauge wire, possibly less, depending on where you want to mount the regulator.
Most, if not all Regulators now include a wiring diagram in the box, for this purpose, just follow the diagram and match up the field wires on the alternator with the ones in the diagram. On a '93 Jeep one field wire should be Blue, the other should be Green.

the voltage regulator is prbably at fault here. with a voltmeter, test battery before and after you turn the engine on. before should read +/- 12.9 volts and while running, should read between 14 and 16 volts. the voltage regulator is in the alternator.

On ALL gasoline models there is no separate voltage regulator. The regulator circuitry is contained in the engine controller. If this circuitry is found faulty, the entire engine controller computer must be replaced as a unit.

REMOVAL & INSTALLATION
(see Figure 1)

This procedure covers diesel models only.




Fig. 1: Pull on the connector body, not the wiring when removing the electronic voltage regulator

1. Disconnect the negative battery cable.
2. Release the spring clips and pull off the regulator wiring plug.
3. See if your bolts are rusty or hard to remove, if so use lubricant and allow to sit for a few minutes before removing.
4. Remove the regulator.

To install:

1. Install the regulator and secure using the hold-down bolts.
2. Hook the spring clips to the wiring plug. Make sure the clips are fully engaged.
3. Connect the negative battery cable.

Hope this helped. (remember comment and rated).

Removal

1. Disconnect battery ground cable (14301) .

1. Remove snow/ice shield.

1. Remove engine air cleaner intake tube (9A624) .

1. Disconnect the generator voltage regulator wiring (14305) to the voltage regulator.

1. Remove wiring connector bracket.

1. Loosen the drive belt tensioner (6B209) and remove the drive belt .

1. Remove the bolts holding the voltage regulator to the generator bracket (10A313) .

1. Remove the voltage regulator from the generator bracket .

Installation

1. Position the voltage regulator on the generator bracket .

1. Install the bolts and tighten to 40-55 Nm (30-40 ft-lb).

1. Install the drive belt over the generator pulley .

1. Adjust the drive belt tensioner as outlined in Section 03-05 .

1. Connect generator voltage regulator wiring to the voltage regulator. Tighten generator Battery Positive Voltage (B+) wire attaching nut to 9-12 Nm (6.5-9 ft-lb).

1. Install wiring connector bracket.

1. Install engine air cleaner intake tube .

1. Install snow/ice shield. NOTE: When the battery is disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more for powertrain control module to relearn the strategy.
   

1. Connect battery ground cable .
