alternator question

Post by chouston99 » Sun Apr 08, 2018 3:16 pm



I think i'm having trouble with alternator charging battery.
Background: I have a newer MOTTOBATT installed which has been on a battery tender for almost all winter. On the 17th of March went for a 300 mile ride with some stop and go (not much). Got back home and did not put it back on the charger. Three days ago it started just fine so I rode to work and only got about 5 miles down the road and and it died on me no power. Sit for a few minutes and got a jump from a good
samaritan and took off riding again to not only get about 2 miles down the road and again poof no power. Trailered it home and put it on the battery charger for 3 days and it started just fine. Did a preliminary volt test before I started it and here are the results.Battery just sitting has 13v , starting it drops down to 12v, at idle of course no charge, idle at 2000 rpm it fluctuates between 12v and 13v it never gets up to 14v.
Thoughts? Thanks

Yep, you have an alternator problem. Common for the brushes to just be stuck and not contacting or could be it just bit the dust. You could take it apart yourself and have a look or take it to an alternator shop.

Dave, I had a similar problem, my alternator went out on my 97se, luckily I had installed a voltmeter on my dash and I had a warning I was loosing power, I died about 1000' from my house...
I suggest you pull the alternator and open it up. In my case one of the winding wires was broken, and if I was more careful I could have fixed it. I also had purchased some brushes and replaced them (before I found the broken wire). I ended up getting a Lacectrical alternator from Amazon, it has worked great for the last year so far.

Again, pull the alternator and take a look, it is actually pretty easy to remove, also consider adding a volt meter, I have them on both my bikes, great piece of mind.

Good luck

I'm with Andy - I wouldn't bother rebuilding an OEM alternator. While they still work, they're marginal at best, while the aftermarket ones (I have an LActrical 95-amp one) produce twice as much juice, at idle, as the OEM ones do wide open. They're actually quite cheap, too - and if you have trouble with it years down the road, the guts are a Saturn car unit, easily fixed at any local alternator shop.

I also got new rubber dampers to install. Do the nipples go in toward motor or out?

Here is a diagram from the parts fiche that may help you see how they go.

Thanks everyone for all the help with the(lactrical high output)alternator install questions. It ended up to be a pretty easy install. I think it was harder to get the old one out than it was to put the new one in. Its running well and has a good charge,now I need to ride it and see how it performs.
