Question about 1984 Moto Guzzi Le mans III

LM3 Alternator Brushes

My brushes on the LM3 are getting a tad short. Can I buy them locally at a Repco or Auto One shop (ie get them this afternoon) or will I have to go through a Guzzi shop ie Moto One etc and have them later this week. I have noticed the charge light is only fading not going out completely the last few days. An inspection this morning showed the brushes are well worn.

Most likely Alternator or Starter Motor. Perhaps get both lots? Best if you have them out and with you Might also try your BOSCH Auto Electrician if the others don't have them. ,,

2007 gmc 1500 sierra charging system works when first started than slowly goes down to not charging

Ah, good old chevy... When the truck first starts and is charging hold a wrench at the back of the alternator, if the alternator is magnetic then it's still charging and could be a loose connection there or a fuse about to go bad.
I suspect that it's the diodes or regulator which is inside the alternator and can still be found at some auto stores - I would also change the bearings as well.
The unit requires desoldering of the connections and cleaning of mating surfaces as the ground I believe is part of the heat sink in the regulator which is about the size of two matchboxes end-to-end roughly. One of the joints may have come undone from vibration and / or heat but typically is a bad connection or something seperating once it gets hot, things will get hot if there is loose or bad connection.
IF the wrench stays stuck to the alternator and shows no charge then it's not the alternator as the magnetic field indicates that it's still doing it's job.
You may find good used local scrap stuff at or .ca here in Canada.
Make sure that any used goods that you buy (guess around 40bucks has no noise - there should be no noise when you spin the alternator. Some places rebuild them for $80 to $100.00 but if you shop around you may find something reasonable at a local auto parts store.
If you can do it yourself it's not that difficult if you have some tools and a bit of patience.
The brushes may have to be held back with some small welding wire for reassembly. You will find pin holes in the end of the brush holders - Feed the wire through the side pushing the brushes back into place first. Dont lose the brush springs when taking it apart.
Mark the casing so you know to assemble it proper.
Remember you may have to desolder the black matchbox unit from the stator coils to remove the regulator.
Bearings can be found for $5. to 8.00 each. The Regulator maybe 20 or 30 bucks. Brushes are cheap but typically not a problem.
I clean the brush contacts with fine sandpaper.
THere are videos on youtube that can detail this process for you and make it easier.
Please leave feedback on your progress..

Good Luck!

I have a 2001 Mazda Tribute with the 3.0 V6. The battery light will come on for a little bit then go off then flash on and off and then sometimes go for 100 miles with no light on at all. I went to a local...

14 amps under load isnt enough, plus the brushes in the alternator may be getting short, thats why the light is sometimes on. Ideally the alternator should be checked while the light is on.

Coleman powermate generator has no output. have changed diodes, capacitor and brushes. i have 12 volts across the brushes but no output at the receptacles. coleman powermate 0545005 5000w

Disconnect the leads going to the brushes, and check for continuity (resistance) of the field winding. You should be able to measure *something* on the order of a few ohms. If you have resistance, then check each brush contact to the shaft that the field winding is on. There should not be any resistance at all, if there is, you have a shorted field winding and will need to be replaced.

Check the resistance of the stator winding next, make sure that nothing is connected to the generator, disconnect the stator wires if you are able (label them!). Check for resistance between the leads (2 wires for a 2 pole, 4 wires for a 4 pole). If there is no resistance, then the stator is open, and will need to be replaced. Also check for resistance from each wire to the frame of the alternator, there should not be any resistance here (indicating a shorted stator). If there is, then you have a shorted stator, and will need to have it replaced.

Replacement is likely to be impractical, probably cheaper to buy another generator with the same engine and keep the old engine as a spare. Still, contact an automotive starter / alternator shop for prices.

Where can I find brushes for the remington model

Remington saw has gone out of business, and finding parts can be a hit or miss experience. Motor brushes in particular are quite rare, so you need to be resourceful in finding a similar brush used in other small tools. Visit a small tool repair shop or check with Ace Hardware (our local store has a whole display box of various sized brushes). If you do find something, buy more because these saws seem to eat brushes for lunch! Good luck!

I had it repaired about a month ago. it needed brushes. and now today it will run but not put no currant out put so it probaly the same thing. But where can i just buy the brushes myself. cant find...

Try starter / alternator rebuild shops. NAPA auto parts sometimes carries a small selection as well.

If you just had brushes put in a month ago, problem likely lies somewhere else. I have several hundred hours on OEM factory brushes on most of my generators, and no problems. Some sets have brushes that have outlasted the engine. Something else is going on.

How do you fix a seized up bearing?

hi are you sure bearing is the problem ?? if your machine is working ok ie running /completing the wash cycle and also draining the used water/rinsing cycle ? but when on spin cycle the clothes are still wet ? if this is the case ? may i suggest that you inspect/check the actual motor brushes ?? as if the brushes x 2 are worne very low they will drive the wash cycle for a time but when spin cycle activates the revs req'd of the motor are lost ie worn brushes will not provide extra power now to change brushes is easy diy and here in uk a pack of 2 new brushes cost approx £5 and if you remove rear cover of machine you will see what looks like auto alternator//this is the motor which is held and adjustable to drive belt in the same way as alternator on a car the elec connection is a master plug so no problem to remove? hope this helps and inspires you ? come back if you get stuck ? or req more info best wishes for a merry xmas

Rinse light flashing on miele novomatic washing machine

Check the motor for worn brushes and or noisy bearings while it is removed for service. Any auto mechanic should have experience replacing brushes and bearings. Much cheaper than ordering a new motor. New brushes and bearings should cost around $30. The shop time should not exceed one hour. Miele charges about $50 for brushes if you can not find a local supplier. The W1930 motor that I rebuilt used a 6202Z and a 6201Z bearing set.
