Once you have disassembled the motor and pulled the armature from the field windings you will need to have an ohm meter. Set the meter to OHMS and then touch the red lead to the winding lead on one end and the black lead to the winding on the other end and if the windings are still good you should be a 0.00 reading or very close depending on the resistance. The reading should be close to the same as touching the red and black leads together. This means that there is a complete circuit end to end and the winding is not broken. IF the meter does not give you that reading you will have a broken winding.

Hello, polys

I was trying to help you out here. Maybe this will help some? I was going backto some customers that asked questions in the recent past and even fartherback. It appeared that no one answeredsome of them, So, I thought I would take some of my personal time to see if Ican help. Even though this Informational site may not have your exact model orbrand, this site will help you a lot. Here is a site link about everything you want to know about vacuumcleaners and possibly yours, from
repair to trouble shooting it. http://home.howstuffworks.com/vacuum-cleaner.htm

Please if this helped you at all, if you can find the time and in your heart torate my help and some kind words written would be appreciated for my free help, I would appreciate it.

Here is also my direct link to my own pages of other areas of my expertise forother problems you might have in Automotive, Appliance, and Electronics. DropIn anytime for my help.

Thanks, Mike

Is a symptom of a burned out starter motor a very heavy electrical draw, without the starter engaging? The solenoid does click.


starter motors normally draw around 450 to 650 amps when starting an engine. The solenoid clicking indicates that there is not sufficient current to spin the armature. The first check is to have a load test done on the battery.( batteries are prone to sudden failure if they are weak to start with and the temperature falls really low. next is to check battery terminals and posts are shiny clean and tight . Lastly if you feel that it is still the starter motor have it removed and bench tested as the major failures are dry joints in the armature bars or worn bushes that allow the armature to hit the poles .The brushes may also be worn below a working levels

Yamaha golf cart 36 volts last set of batteries get hot awhile driving


batteries will get hot when working as there is current flow across the plates . For batteries to get noticeable hot then there is a current draw that exceeds the capacity of the battery . This indicates a problem electric motor in the system (Worn bushes/bearings -armature poling out --shorting windings or armature) it may also indicate shorting between batteries from a battery that has collapsing cells . Have each battery inderpendently load tested

Path Of Electricity thru electric drill motor


to test the field you need a VOLT-OHMS meter and take a reading across each of the leads and they should be about the same, on the armature check EACH comm segment and they should all be about the same. DO NOT remove any wire without first making a schematic of where it came from.

Electric motor makes loud grinding sounds and vibrates badly


It could be your armature bearings need to be cleaned and repacked with grease or heat has caused the windings of the armature (shaft with wire coil attached) to wrap and needs to be to be rewound. Worst case is the armature shaft could be bent. You will have to disassemble the motor to get an Idea what the problem is. Clean the bearings and armature and look for contact rubbing on the armature and magnets. Check the shaft for balance and shaft straightness.

How to change a starter


Starter - There are like 2 or 3 bolts on most starters that are long and go into the engine block. Then there is the electrical positive connection which should be removed only after the battery has been disconnected to avoid shock and fire caused by a short in the electrical system when disassembling or assembling (warning: this a safety measure designed to keep you from hurting yourself or the car). Assembly is the reverse of the removal.
TESTING No-Load Test Make the connections as shown in the illustration. Close the switch and compare the rpm, current and voltage readings with the specifications found in the chart located in this section. Fig. 1: Proper connections for the starter no-load test 87952035.gif
  • Current draw and no load speed within specifications indicates normal condition of the starter motor.
  • Low free speed and high current draw indicates worn bearings, a bent armature shaft, a shorted armature or grounded armature fields.
  • Failure to operate with high current draw indicates a direct ground in the terminal or fields, or frozen bearings.
  • Failure to operate with no current draw indicates an open field circuit, open armature coils, broken brush springs, worn brushes or other causes which would prevent good contact between the communtator and the brushes.
  • A low no load speed and low current draw indicates high internal resistance due to poor connections, defective leads or a dirty commutator.
  • High free speed and current draw usually indicate shorted fields or a shorted armature.

Electrical spark unit stoped . Getting power through switch but motor will not start.


More than likely you have a worn brush. If the breaker was running good and then just stopped this is the case. These brushes have a pop-off feature that will stop the motor when it is time to replace the brushes. If you replace the brushes and are getting a lot of sparking, the armature or field more than likely may have a short. Sometimes its the armature, sometimes it's the field, and sometimes its both (running short). You have to have a short tester and a growler in order to test for the shorts. One thing to look for is any burn marks on the windings of the armature, and look for scarring on the inside of the field which may have gotten damage due to rubbing from the armature. An imbalance in the electrical field can push the armature into the side of the field while it spins.

Hotpoint Aquarius WMA42. I was using the machine when there was a bang and the electrics tripped. I reset the fuse box, checked the plug fuse and the socket but still nothing. No lights so presumably no...


It more than likely is the motor that has shorted. Remove lower rear panel, remove belt. Undo 2 screws that hold motor in place, remove motor plug, lever motor back to remove same,
Remove carbons and check for wear, also look at armature and see if there is any sign of shorting, clean armature with emery paper, fit new carbons, refit motor and belt, test.

If it still does not work, then in all probability it will have blown the main control board.which would require replacing.
