SOURCE: Getting NO power from the MR2 160/2 Mecc Alte Spa

There are a few more components to check in the system. From the information provided this is not a Kohler generator as Kohler makes all their own AC alternators under 350KW, seems you may have just a Kohler engine (probably a CH25). Cannot find any info on the voltage regulator which leads me to believe it may be integrated into the main controller. Curious to know who the manufacturer is. If the capacitors are good, try checking the diodes. A volt/ohm meter with a diode check will do. Voltage reading on one side and nothing on the other. If you have no access to a diode check feature, try reading it through a battery NOT SHORTED TO BATTERY hook a meter to a battery and put the diode between one of the leads to the positive, one way will read voltage the other will read open, no voltage, or OL. Look for any fuses or breakers blown / tripped. 6 VAC on the output is about residual voltage meaning voltage the alternator makes without any help from a voltage regulator or field voltage. This usually means the alternator / rotor windings are still good. This alternator is brushless so you could seperately excite this unit via a 12V battery through your field. Look for your exciter field winding, it should have some kind of label on it saying F+ and F-, apply 12V here momentarily on + & - respectively with the unit running and you should see your output voltage spike. This tests the alternator. If this tests ok, then check to make sure your wiring / fuses from the alternator to the controller or voltage regulator (voltage sensing leads) are ok. If all these check ok, it is likely you have a bad voltage regulator.

I need the capacitor for a Mecc Alte Spa Generator Type T20F-200A 15KW


Take the specs off the capacitor and look it up on-line. Should be able to find one easily. You can also try your local electrical supply house.

ENGINE CUTS OUT, AS NOT CHARGING BATTERY.HOW DO I CHECK, CHARGING SYSTEM ON THIS MODEL?


you will require access to the end of the alternator from the drawings on the pramac site the alternator looks like it could be made by mec alte spa if so there are spec sheets on their site for the alternators, remove the end cover of the alternator and there should be a bridge rectifier in there which will need testing also the spec sheet should give the resistance of the coils so you can check them you will need info from the data plate on the alternator, if it is mec alte spa then find your product herehere

On 92 honda civic the battery light stays on. Is


No your alternator is not longer working correctly. It could be as simple as a broken alternator drive belt. Open the hood an see if you see any naked pulleys. If the belt is in place then you most likely with have bad alternator. NAPA and Autozone have stores that can test your old alternator. Con comeone into removing it and have it tested. If it is bad get a REBUILT one. A new one will cost a small fortune!

I need to replace my alternator


You need to first take off youre serptine belt. Inspect that and generally its a good idea to replace. Next there is a electrical connection on the alternator. DISCONNECT the battery FIRST!!!!!!!!!!!!!!!!!!!!!!!!! then disconnect the connection on the alternator, there are a couple of bolts that attach the alternator to the engine. and then simply bolt on the new one, re-attach the electrical connection and then re-install the (new) belt.

How to replace 83 honda accord alternator


The very first thing you need to do is disconnect the 12 volt battery source, remove the positve lead as well as the negative lead to be absolutely sure, you must be careful, I would wear safety glasses as well cause anytime you work around batteries there is a possibility of spark and ignition that can cause the gasses produced by a battery to explode sending battery acid into the air and on ones self.

Next locate the alternator adjustment bolts , wire leads connecting to the alt. mark those necessary wires so that you will be able to install them back into their proper place on the new alt. remove alternator belt and note conditon, often this is the best time to replace it with a new one. once you have all bolts loose thne you can lift the alternator from it's rest , take careful note of any spacers used on the pivot mount side of the alternator as well as any wire leads connected you could not see from above. replace in opposite mannor as removal... hope this helps..

Need a diagram for this overcomplicated machine


Will probably bin it. Long experience shows that the ONLY alternators worth having are the British made Newage-Markon which IMHO are superior to both Sawafuji and Mecc-Alte. Voltage Dependent Resistors (VDRs) also known as Transorbs are essential if long term reliability is desired from small gensets. Haverhill Generators get around the voltage spike problem another way - 8 microfarads across the output but one Haverhill generator that I repaired had vibrated apart its control box wiring and fan. These little machines all leave a lot to be desired unfortunately and seem to give endless trouble.
