Old Alternator

Post by curtm »



I replaced the alternator on my 1500 last summer and have old 30A sitting on my bench, Question are they worth rebuilding or dumspter it ??.
Kinda hate to throw it out but, Is it worth the trouble to repair, I did all the necessary checks on it and turn out the voltage regulator is bad
thanks Curt

I would keep and repair it. You can find the parts on internet for a reasonable price.

I also replaced my OEM alternator for a 90 AMP unit. It only had just over 10,000 miles on it. I'm going to take it to a local company that rebuilds alternators and have them upgrade it as large (amps) as possible for the frame so I have a backup..................

If it is a pre 1996 yes they are worth rebuilding and can also be upgraded.
Ken Hemmings rebuilds and upgrades the output if desired. He has high reguards in the wing forums for the quality of his workmanship.

When my OEM went out I replaced it with a 90 amp and put a new regulator in the OEM, about $30 I believe. It wasn’t the easiest job, but it can be done.
I plan to carry it and the tools needed to replace the alternator while on longer trips so we’re not stranded.

Yours is made in Japan. Everything today is from China and subject to early failures.
Ken will rewind it to put out more than you'll need and last far longer.

The OEM off my 1999 says it was made in Japan. The only regulator or any other parts I could find are from China.
WPS bought out just about all manufacturers of electrical parts for autos and motorcycles.

Correction. WPS is a subsidiary of WAI Global. WAI Global parts are manufactured in China and sold all over the world. //www.waiglobal.com/
Next time you are in the local home improvement store, look at where the power tools are made. Almost all are made in China.
China has new state of the art facilities and their products have greatly improved in the last few years, which is good because everything is made there now.
When shopping for a new alternator, I called quite a few alternator shops and they all said their parts come from China.

I'd keep the unit as a spare. Take it into an alternator repair shop, have it tested. I also thought that the OEM alternators were 40 amp. Always good to have a spare, can be used as an interim if the replacement alt fails and has to be replaced. Not many vehicles on the road today that isn't full of off shore parts.

I have been out on a several days long group ride and had a near new Comp-U-Fire rotor suffer a appearant fractured solder joint of one rotor winding it was determined, I was plumb tickled to have a friend pull his old, refreshed OEM unit from his trailer and offer it …. sure, voltages were lower under higher loads at stops (I was pulling a well lit trailer as well), but that OEM got me home … and after getting my CuF fixed with new rotor, I returned his spare.

Later, I picked up another CuF from a wreck, then I was later given a still working OEM when another rider cleaned out his stuff.

I always carry a spare alternator. The one time I needed it when my alternator quit 100 miles from home I was very surprised that my spare was sitting in my parts cabinet at home. You can bet I won't make that mistake again, LOL

I have my OEM together, but haven’t come up with a way to spin it for testing. I don’t want to install it on the bike to test it without knowing it won’t short out. Also, don’t want to chance an oil leak from removing/replacing the alternators.
I’m thinking of using an old timing belt and electric motor to turn it.
Anyone have any ideas?

Take it to Advance Auto and they can test it as well can most any small mom & pop type electric motor repair shop.

I wasn’t sure they could spin it without a pulley on it. I will try them out though.

And they may say they can't, but when I had the rotor replaced in my Comp-u-Fire which has vanes, etc just like OEM GL1500 Alternators, the fellow used the adapters to mount the alt to the machine, looped the belt over the vanes like they were the pulley, and tested it as I watched. Once they get it secured to test machine, just need to pull it to tighten belt. It'll spin. It may not be as smooth as a pulley, but it'll work.

One day at my part time job at Advance, a fellow wanted us to test his. The regular full time commercial parts man had it on the machine rigging the belt before I walked over to see if he needed input, he had it covered. Another parts fellow had told the guy no when CPP overheard convo and jumped in.

Could you use a drill to spin it, you may net get the full voltage out of it, But you could tell if it is working, wonder what RPM it spins at when on the bike ??

I can probably make an adapter from an old hose for the drill and try it. Once I know it won’t short anything out, I can put it on the bike to check the output.
According to the manual, it should start charging 800-1,000 RPM. At 900 RPM/ 0-2 amps/13.5-15.5 volts. At 1850 RPM/ 1.5 amps/ 13.5-15.5 volts.
I want a spare for longer trips. It’s too easy to replace not to have a spare and tools to keep from getting stranded.

Any one know what bearings go in these alternators before i put the voltage regulator in it ???

Die grinder with a socket adapter works , they spin 20000 rpm's but i throttled the air back to get about 1500 rpm's

ok here is the bearing numbers for the Oem Hitachi LR40
front NSK 60/22DU
Front seal is NSK AE1133G
Back is NTN 6000LU
if anyone needs them

before i spin it up do both wires on the plug in get battery power, according to book it says white wire gets bat voltage and black gets voltage when key is on, thus bat voltage ???? and output voltage from alternator on large stud (big wire)

Dont want to burn anything up

thanks Curt
