Alternator not charging

Post by JPochron » Sat Jun 08, 2019 1:24 pm



Thursday I installed the fuel pump and it seemed to be running fine. Friday I rode it about 20 miles to get inspected and registered seemed to be no issues. The Jensen radio I installed has a low battery warning and on my way home which was just a few more minutes down the road I start hearing a beeping and saw that the low battery warning was beeping I turned off the radio to save power. I started to take off from the light and it died. Called a friend to come jump start it and it would start but die as soon as I put it in gear. Went to my house got the battery out of my 89 goldwing and was able to get it home. I put my Fluke multimeter on the battery and at an idle it was 12.36V and consistently started dropping 12.35,12.34,12.33 and so on I watched it drop more than a full volt. At a higher RPM it started dropping faster and connecting to the lead with the rubber boot on the back of the alternator was barely giving me a reading. I'm quite certain the alternator is bad but want to ask the forum if there's anything else i can do or check to be sure. I bought this trike in December and new it had a few issues like no rear brake and running poorly. Got that all taken care of and decided to install a bluetooth stereo system and get it painted. While removing the plastic for the paint job I discovered several of the plastic had broken tabs and replaced all of those. Also the front wheel and forks were encased in oil and I'm sure the fork seals had leaked or are still leaking. After I got the trike home and it sat in the garage for a short time I noticed a small of mount of a thick black oil on the ground under the right fork. If the seals are leaking can anyone tell me if they're difficult to replace? Sorry for the long rant just a bit frustrated that everytime I get 1 thing fixed something else pops up. Thanks for all the advice

It seems pretty certain you have an alternator problem. It could be as simple as the brushes worn down or stuck. The alternators are not too hard to remove. If you have an alternator repair shop locally, you could take it to them to have it checked and repaired. If you are mechanically inclined it would not be hard to take it apart and check the brushes for length and give it a good cleaning. That just might be all that is wrong with it.

Thanks. I'm thinking since it's more likely to be the alternator to go ahead and replace it with an aftermarket 90 amp alternator. I've add several extras like radio, amplifier and LED lights. So it would be a wiser choice to go with a larger output alternator.

I finally removed the alternator with much aggravation it was a heck of a time. Can anyone tell me if the dampers are separate pieces or are they all connected together. I pulled 2 of them out and from what I could see the majority of them are joined together but the 2 I inspected appeared to have a small section broke off that looks like joined them together. If anyone has any experience with this I'd appreciate some insight

Thanks

They are connected in pairs.


I would definitely replace the dampeners when you reinstall the alternator (OEM or aftermarket). They are not very expensive.
As Bellboy pointed out, the brushes may be worn or stuck. You can get new brushes for an OEM alternator pretty reasonable also.

Thank you after looking at pictures at some of the parts houses I was able to see as you stated that they're connected in pairs. I did purchase them from Cyclemax also. I went with the Hitachi 90 Amp alternator because I have an amp and LED Lights rather be safe than sorry. I'll check the brushes on the old 1 and hopefully sell it. Seems I fix 1 thing and something else goes out. Hopefully this will be the end of any other failures

I took the alternator apart and 1 of the brushes was broke in half. Seems kind of odd it could break like that. I guess i'll order some new brushes and sell it then

I put a new 90 amp on mine and installed a new regulator in the OEM. I plan to keep it for a spare while on longer trips.

After I removed the alternator I noticed some of the dampeners were broke into 2 pieces. Do the usually break and if they're broken apart will they still function?

Always a good idea to replace them if the alternator comes out, they get hard and brittle with the heat.

Cyclemax has them, $17.50. Local stealership likely has them too.

Thank you I had purchased them from cyclemax but he didn't ship them right out and I needed them right away so I had to cancel. I think it was like $23 with shipping but I bought them from a local Honda dealer for $25. I did purchase the brushes and fuel petcock from him
