Hi and welcome to FixYa,

The yellow wires could be interchange. It does not matter which yellow goes to which connector terminal as it is a 3 phase alternator. The voltage regulator has a built-in diode pack that would convert all 3 incoming ACV to a single charging DCV.

It would be normal for them to heat up especially when charging condition. However, on older machines, this is more caused by corroded, tarnished or loose contacts. It would be to your advantage to clean and tighten these connections/connectors.

Good luck and thank you for using FixYa.

Wiring rectifier correctly?


You are discussing a bridge rectifier, the + connector is directly opposite the negative connector, the remaining two connection points are the AC side of the rectifier + AC

My FR691v-as07-R toro timecutter's battery discharges while running. Replaced the Battery, voltage Reg and Diode, still discharges.


It sounds like a job for a volt/ohm meter.

I am not familiar with the model but the basic principles are fairly consistent.
Either there is something causing the battery to discharge at a greater rate than the generator can recharge it or more likely the generator simply isn't working or isn't working efficiently.

In order to charge a battery the generator must provide a higher voltage than the battery or current will not flow. Assuming a 12 volt system the voltage of a fully charged and healthy battery is 13.2 volts. The generator must provide a higher voltage and typically would be around 14.5 volts for solid-state or electronic systems and 15.5 volts for electro-mechanical systems.
Scale the voltages up or down for 6 volt or 18 volt or 24 volt systems...

Isolate the battery from any battery-supplied accessories and then with the engine running fairly fast check the voltage across the battery. If only the battery voltage is present it indicates a generator problem.

As well as providing a higher-than-battery voltage the generator and all the associated wiring and connectors must be able to provide the current flow. In the case of problems it is best to go back to basics and carry out a visual check of all the wiring and connections and check the continuity and insulation of the generator windings and wiring, rectifier diodes, brush gear if there is any fitted and earth connections if it is an earth return type system. It is a good idea to use a wiring diagram for reference.

If the generator is a permanent magnet type there have been rare occurrences where a generator has become inefficient due to a loss of magnetism. I repeat this is a rare occurrence and the fault probably lies elsewhere and a systematic approach and reference to a wiring diagram will usually isolate the fault.

Good luck!

Why wont my generator generate power?


You need to provide more details than that. I assume that the engine is running. If so and there is not power output which you will have to check for there are a multitude of possible reasons. You could start by a visual check of wiring and connections. I also assume it is a permanent magnet alternator type and not an excited filed type which is an entirely different state of affairs to test etc.Then find the voltage regulator which mayor may not be integral to the alternator depending on make etc. If it is a permanent magnet type of alternator it will surely be an external regulator, Check for AC voltage into it, DC Voltage out of it if it is a rectified to DC system or AC out if it is an AC system, check for a good ground from its case to the engine/frame ground. Identify the stator windings and do a static stator check on it. If the stator and regulator check out good in a permanent magnet type of alternator you probably have simple wiring issues.

Need wiring diagram to figure trickle charger out


Check the stator for AC output to the charge rectifier, if present stator ok, then check DC on DC side of rectifier if not present change the rectifier, ssuming all fuses have been tested

If I run the generator for several hours it will die do to low charge on battery


Check the battery voltage before you start it at the generator. IE 12V start the generator and measure again. It should be around 13.8V if it does not rise, go to the charge rectifier in the genset and make sure you have AC going onto it. (Assuming you have the gen battery charge option) If you don't have ACV you can suspect the B stator windings, if you do have AC. Check the rectifier DC output 13.8V if present check wiring and fuses, if not present change the rectifier, note where the wires go ! The battery is dying because the ignition system of the gen is pulling it down and it is not charging.

How can I make my 15.5 h.p.kohler charge again


Check the rectifier to make sure you have AC power on the AC terminal, if you do stator windings are good, if not stator is bad.
If you have AC then check the DC wires on the rectifier, if you do not have battery voltage, change rectifier, if you do suspect wiring / fuses

Generator is not converting over from 110 to 12 volts, why not?Need a wiring diagram for the convertor box also.


You did not mention your model number, however most generators do not have the 12v charging option. Those that do like yours generally use a seperate winding producing about 14volts ac which is passed thru a full wave bridge rectifier. This rectifier us usually mounted inside the panel usually against metal to absorb heat (gets hot while in use). Look for (about one inch square) rectifier and test with meter. Replacement can be of the Radio Shack variety. Good Luck

No ac power from generator


One sure thing is you better find a competent service guy.

It sounds like you have lost excitation to the field of the alternator. Without documentation I can't tell if this is a brushless type or brush type rotor.

In either case, the excitation needs to be restored. On a brushless type, either lack of residual magnetic flux to start the buildup of the field OR failure of the rotating diode(s) can be the problem.

In a brush version, investigate "flashing" the field on Google or trace out why there is no voltage to the field. Possible things for this are failed transformer, failed rectifier, blown protective fuse and or wiring.

It shouldn't matter. AC is not polarized; that's the job of the rectifier block.

Do not field out the field wire.
Is the alternator ight coming on?
If you rev engine, does charging system start working?
There is a resister wire that provides voltage to the field circuit. If the resister is bad, you will only get voltage to the field through the dash alt. light bulb when you push enough voltage through it.

I don''t have 1993, but here is 96:

Generator with Integral Rear Mount Regulator, Internal Fan Type With the key in the RUN position, voltage is applied through the charge indicator lamp I circuit to the voltage regulator. This turns the voltage regulator on, allowing current to flow from the battery sense A circuit to the generator field coil. When the engine (6007) is started, the generator (GEN) (10346) begins to generate alternating (AC) current which is converted to direct (DC) current by the rectifier internal to the generator. This current is then supplied to the vehicle's electrical system through the battery positive voltage (B+) terminal located on the rear of the generator. Once the generator begins generating current, a voltage signal is taken from the stator and fed back to the voltage regulator S circuit, turning off the charge indicator/lamp. With the system functioning normally, the generator output current is determined by the voltage at the A circuit. This voltage is compared to a set voltage internal to the voltage regulator, and the voltage regulator controls the generator field current to maintain proper generator output. The set voltage will vary with temperature and is typically higher in the winter than in the summer, allowing for better battery recharge. With the system functioning normally, the generator output current is determined by the voltage of the A circuit (battery sense voltage). The A circuit voltage is compared to a set voltage internal to the voltage regulator, which controls the generator field current to maintain proper output. The set voltage will vary with temperature and is typically higher in the winter than in the summer, allowing for better battery recharge in the winter and reducing the chance of overcharging the battery in the summer. A fuse link is included in the charging system wiring on all models. The fuse link is used to prevent damage to the wiring harness and generator if the wiring harness should become grounded, or if a booster battery with the wrong polarity is connected to the charging system.
