Low voltage of genset will affect the use of generator set, which is one of the common faults. This article will guide you to learn the factors that affect the voltage of generating set.

1. The unstable speed of the engine causes the unstable voltage of the generator set.
2. If the load on the generator set is too large, the voltage will be unstable.
3. The damage of the voltage regulator components of the generator causes the unit's voltage instability.
4. The poor circulation of the fuel pipe of the genset causes the unstable speed of the engine, which causes voltage instability.

While the below is not an eclipse, it is suggestive.

The only requirement needed for running your "E" or "F" series Engel Fridge - Freezer (The later Models) on a 240 volt generator is to ensure the generator you are using is A.V.R. Automatic Voltage Regulated. Please refer to your generators user manual. If it is an older generator with A.V.R., it doesn't hurt to add an in line spike protector or surge arrestor.

have the voltage regulator system checked
in the regulator the voltage controls the amperage allowed and it that unit is not working properly then there will be no current out put
that regulator could be part of the control board for the main ac out put and may have developed a fault in the section for 12 volts on the board
there is a limit on the charge rate for the battery and if it is exceed it may have damaged that circuit or possible blown a fuse in the amperage circuit

Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.
Visual Inspection Chart Mechanical Electrical

• Battery case, posts, hold-down clamp, cables and connections
• Generator drive (serpentine) belt for condition and tension to make sure there is no slip between the belt and the pulley. For additional information, refer to Section 303-05 .

1. Check the operation of the charging system warning indicator lamp (instrument cluster). Normal operation is as follows:
   • With the ignition switch OFF, the charging system warning indicator should be OFF.
   • With the ignition switch in RUN and the engine off, the charging system warning indicator light should be on.
   • With the engine running, the charging system warning indicator light should be off.

1. Verify the battery condition. Refer to Section 414-01 .

   Your whole problem is the alternator is not charging , a couple tests with a volt meter would tell you !

no,it is wired for 120 you can only run two legs to make 240.you need a different generator for that

you have a starter generator... you can go to most specialty 12 volt shops ( starter re-builder ) or online and find a good quality universal V.R. can't remember if thats a 6 or 12 volt system... google 12 volt external voltage regulator and you will get an idea what I am talking about. I've done this repair a number of times

The terminals you listed are correct.
T4 -T7 mated
T5 -T8 mated
T6 -T9 mated
10, 11, 12 combined connection

L1, L2, & L3 = output / line leads

However you should have 277 VAC line to ground and 480 VAC Line to line (Across any 2 phases)

So terminals 1, 2 or 3 to ground should be 277 VAC (L1 L2 or L3)
1-2 or 1-3 = 480 VAC
any combination of
1 , 2, or 3 to each other = 480 VAC

As a "generator man" with 19 solutions one being "You might have to sting it" you should know this and be able to use the diagram on the power head to get your desired voltages unless the wiring data plate is missing. I have had to dial in voltage regulators when switching between 240 and 480 to prevent automatic shut downs from over / under voltage.

Can you manually adjust the voltage on the generator without load?? If you have 120/240 60hz output on it and you are not overloading the unit (amperage), then it may be as simple as adjusting whats called your gain setting for your voltage regulator. Obviously you are seeing what happens when it is set too low. Trying raising that setting until it becomes unstable then back it off. Unstable meaning voltage starts jumping all over.

Double check your brush istallation. positive side toward rotor bearing, if you put 12 vdc directly into brush pack and check with a meter at the 120 vac outlet and have low or no voltage, you may have no resistance in your rotor slip rings, excitor & main windings also need a resistance check. 12.6-16.7 ohms (rotor) 2.26-2.80 ohms (excitation) .26-.32/.28-.35 main or power windings. Note: unit running when appling 12 volts to brush pack. 2-5 second only, ( This test tells you the rotor & stotor are ok )
