SOURCE: Suzuki SE4000SED generator with no output

There was a day and time when generators were simple. There were no capacitors, regulators to control/adjust power to magnet or ground fault outlets. Winding getting hot indicates short, however could be bad capacitors. Rectifiers and capacitors must be removed from circuit to test properly. Here is a simple test that I use to find fault area. I use a small power supply (16v AC 1 amp like doorbell transformer) into the 110v outlet of generator. This should energize the armature magnet and actually produce voltage at commutator with brushes pulled off. You can slowly pull the starter rope to move the armature into a different positon the voltage will vary. If the ac windings are shorted there will be very little or no magnet. There is a seperate 110 v circuit at the 220v outlet to test (there are two 110v windings that make up the 220v outlet, one is also used for the 110v outlet). There is another winding that products voltage for the regulator that powers the magnet thru the brushes but I think that circuit is porbably working because of the heat in the windings. You might even have 110v power at the 220v outlet. As our parents told us over and over, be careful when working with electricity. Enjoy

Ok I'm going to try this from memory...last time used it was a few years back when wiring up a big boat. Large (B+) wire goes from battery to large terminal on alternator back. Facing the rear of the alternator, top spade connector on alt goes to a switch (there was supposed to be a resistor in that wire, but I never used one) switch connects to (+) on battery. Terminal on right goes to the (B+) terminal on alternator. Alt case is ground.
I can't find my old chiltons electrical book but that is how I remember it.

HAVE 110 WHEN PLUGGED IN OR ON GEN BUT HAVE LOST 12V WHEN UNPLUGGED OR GEN OFF.


Do you have 12v when plugged in or on generator? If you do, then it's likely 1) a fuse or breaker for the converter, or 2) the converter is dead. Is your battery good? Try using taking the battery out and using to crank your car or truck. If that works, look at the fuse or breaker for your converter or your converter may be dead. If the batter doesn't work, do the opposite and put your car/truck battery in your RV and see if your 12v works -- if it doesn't, then check your converter fuse/breaker or it may be dead; if it does, then your battery is terminally (pun) dead.

How do I connect a warning/ignition light to my alternator?


Hi Glen
All depends what you mean by warning lamp.
Early Alternators used to have a terminal connected to the "Star" winding inside. A 12v lamp connected between here and ground will light up when a charge is available.
But.... the simplest method is to buy LED charge lamp which checked for voltages above 12v (12.5 to 14v} and lights up showing a charge. I can buy a simple device like this from my local Jaycar Electronics store. You should be able to get a similar device depending on where you are

Good Luck

How do I replace a generator with an alternator?


here is a short video, where the guy replaced a 6v generator with a 12v alternator, if you click on more under video there are instructions listed.
if you are going from 12v to 12v it will be easier.
if you are going from 6v to 12v there are other modifications that need to be done, so as not to fry to light bulbs, ect...

also keep in mind that some of your older cars have a positive ground ( I've run into this on some of the fords), if this is the case , the vehicle will have to be converted to negative ground.

How to test the electrical system of the generator for free


Ez test to determine if stator wiring is ok. This test works on generators that have two sets of 115v plugs and 220v plug. Use a 12v, 1amp ac power supply ( smaller ac power supply should work ok ). With generator not running, apply 12v to one of the 115v outlet plugs. Now verify 12v output voltage with meter at another 115v outlet on generator. Also verify that there is about twice the voltage at the 220 v outlet plug (should be about 20v - 24v) . If the adjoining 115 v outlet plug has no output or very little voltage or if the 220 volt plug has no output, most likely stator is damaged or breaker is off. If the stator is shorted voltage reading will be very low and power supply will heat up. If stator is open, there will be no voltage at second 115v plug or 220 v plug. If voltage is ok at the other outlet plugs as per test above then most likely problem is with voltage regulator, or brushes not making contact or armature winding open or just needs to be energized. Unplug the 12v power supply after test to prevent it from overheating. Most generators have two 115v windings that together power the 220v plug. When you energize one of the windings with the 12v power supply, the second 115v winding will be energized also and give you a voltage reading about equal to 12v. You will not damage the generator with this small voltage being input thru the plug. Good luck

Intermittent charging


Generally that indication implies generator failure. Generator failure can come in multiple forms. A faulty ground will cause the generator not to charge and potentially burn it up. A severed phase wind (remember, your alternator is really a three-phase generator with a six pulse front end rectifier set) will cause the light to intermittently come on along with weak charging output. A voltage regulator failure will cause zero field current in the rotor. A brush failure will also cause a generator failure light to come on and stay on. A rectifier failure (any of the six) will cause the generator not to charge properly and turn on the MIL and generator failure indicator (looks like a battery). The condition of the battery can also cause generator failure, if the battery is defective (buckled plates, weak electrolyte, low water, etc.) it will place a very high load on the generator continuously, causing it to 'full field' the rotor which can cause the rotor to overheat and fail. Never run a generator without the battery terminals connected as this will cause it to fail quite spectacularly. Do not attempt to verify output of the generator with the battery terminal leads disconnected.

If generator failure is indeed the cause, find out why. Generators rarely fail. When they do, it usually is caused by poor ground connections, corroded battery terminals, high continuous loads, electrical faults and poorly-wired ancillary equipment, such as head units, amplifiers, inverters, etc. Always check all these out when replacing the generator. Never run a generator without the battery terminals connected as this will cause it to fail quite spectacularly.

No power from alternator to battery


Is the battery ignition light coming on when you turn the key on. Wiring for an alternator is quite simple, the 60amp cable (thick wire) is a direct feed to the battery. The thin wire (normally blue) connected to the 'ing' terminal gets a live feed via the battery ignition light. if the bulb has blown or this wire is not connected, the alternator will not charge. If you can, use a 12v 5watt test light connected to the battery, start the engine and touch the 'ing' terminal. this should prove and energies the alternator to start charging.

My battery light indicator on dash board stays on


This is usually caused by a faulty alternator.
It stays on because the alternator is not generating sufficient voltage on the control winding to extinguish it.

Check battery terminal voltage while motor running with headlights on or blower fan running.
Terminal voltage should be approx 14.5V.
Ensure alternator and engine are properly connected to ground and the battery negative terminal.

I have a 3 wire alternator i need to wire


Assuming you have an external voltage regulator:-

The largest stud/nut terminal is B+,
this is the charge current output, it connects to battery positive (uses heavy high current capacity cable),

the other terminals are normally spade terminals :-
DF exciter winding control, (controlled by ext voltage regulator);

IND (or D+) - via dashboard 'BAT' indicator light, then to +12V when Ignition switch is 'ON' (alternator excitation current source).


If you have an alternator with an integral internal voltage regulator,
only B+ (sometimes with an additional B+ terminal)
and IND (or D+) terminals are present.

Solar connections for 12vdc houseboat system


Hi,

Based on your post/description, I would suggest that:
1. There is no need to install a diode from the boat motor alternator since most current design used electronic regulators with built-in diodes. The output of the alternator therefore could go straight to the battery or a switch (*selecting battery 1 or 2);
2. It would probably be safer that you would install a diode after a portable generator since some design do not need/use internal rectification but are connected straight to the windings/coil;
3. There is no need to install diode after each solar panel.

To my understanding the Plasmatronics have built-in in-line diodes to its inputs/outputs (unless otherwise required such as with the "Catch Diode protection" across the load). Additionally, unlike in some other system, a PL-20 would require that the negatives not be tied to a common ground. The PL-20 is relatively a straight forward connection (it's the programming that is a challenge).

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Tight lines.
