Getting the last drop out of brushes

Just rechecked the new brushes after 80 miles. They are slowly wearing in to match the rotor. My on-board voltmeter has not shown any unusual voltage fluctuations so all seems fine with the DIY brush setup.

I don't think it's important for the whole face to contact the rotor. If you were to read ohms from a point on the face vs reading from something in contact with the whole face I don't think there would be a difference. You could test that by measuring with the point of the probe and then lay the probe on it sideways and read again. But the larger the area the slower it would wear for a given spring pressure.
 
Thanks for the Update Paul !!!!!
I got my Digital Voltmeter mounted last night, I decided Not to go with putting it in the console or dash board as I would loose one of the indicator lights...so instead I Shoe-Gooed ot to the handle bar by the right clamp under the Key switch !
seams to work just fine...14.0 volrs at about 3k RPM ( guessing as my tach quit again ! )

I should'a bailing-wired it on there just fer you LOL !!!! I bet you would'a appreciated that'en ! HAHAHAH!

Made me laugh.....Then I had to look up Shoo Goo.

Product history
Origins
Shoe Goo was created in 1972 by Lyman Van Vliet, a 45-year-old senior executive at Hughes Aircraft Co. with a degree in physics from Wayne State University. A frequent player of tennis, Van Vliet was dissatisfied with the durability of the soles of his tennis shoes and sought a method to extend their life by repairing them.

Although Van Vliet already held several
patents related to the aerospace industry, he had no extensive background in chemistry. Nevertheless, he set to work to create an adhesive which could be used to create a pliable surface coating for shoe soles, whipping up his experimental blends in a spaghetti pot. The ultimate result of Van Vliet's efforts was a polymer that was eventually marketed as "Shoe Goo".

It appears that Shoo Goo has its roots in the aerospace industry so maybe you are on to something there. That being said...... please add at least a small piece of bailing wire so we all feel better.

Just joking here Bob, while I'm not ready to use it for motorcycle assembly I appreciate your earthy ingenuity. And it possibly works even better than bailing wire.

LOL well, I took a file and scratched the hell out of the chrome on the handle bar where it is glued to... Hopefully it will stick good but there is no guarantees.... the meter is waterproof ( or so they say ) and the wires just run into the headlight bucket where the key switch plugs in at
so I just tapped the brown wire from the keyswitch for the power.... it turns on and goes off with the keyswitch and shows the voltage going through the entire system..... Well mostly.
so far it's staying on there ! HA !!!!!!

LOL you guys ! shoe-Goo is like silicone it dries to a real flexible rubber so the meter has a soft mounting !!!!!
the question is ....will it stay on there or not !!!!! it is real easy to remove just use a razor blade ! or pocket knife ! LOL

the brushes are barely adequate to handle the load stock.... so if the contact is not perfectly flat on the copper strips the brush will ware extremely fast till full contact is made..... unfortunately what ya need is larger brushes but the holders are very small.
that's my take on it !
......
Bob........
 
Indeed they do Paul but as 2M pointed out the brushes are not big enough to handle the load so if you have a bad battery that needs constant charging or extra loads like a bunch of lights drawing more amps the brushes will ware allot faster than normal because they are too small
...so....keep a good battery in it and don't add 2 more headlights !!!!! and you should be fine ! LOL

Quick Update: My DIY alternator brushes made from universal motor brushes (See Entry 32) after 600 miles show no significant wear - Original length 15mm and now measured at 14.9mm. This rate of wear seems very good!
 
Thank you for the update Paul.... I was wondering how long they would last not being OEM <grin> seams as good if not better than the original !..... very Nice....
after buying 3 bunches of brushes I have yet to obtain brushes big enough to fit ! they either sent the wrong ones or I ordered the wrong ones
but the fact is their all too small and buying large brushes just seams like allot of work.... but after 3 tries I guess I'll buy over size brushes and sand them down....
thank you for the help and posts !
Bob.......
