motomojo taz 150cc, have to charge every other day. By ruckingoodtime (Read 3,855 times)

SO I just got this motomojo taz 150 scooter (QJ157QMJ) and I seem to be having an issue. The guy I bought it from said that he put a new battery in it, which seems really small and is only 50cca. But I'll charge the battery, and start and shut it off multiple times during the day, with the longest ride being 15-20 minutes at about 1/2-3/4 throttle (35-45mph) I can do this a few times for a couple days and then I'll have to put it on the charger. Earlier I started it and hooked up my voltmeter to see what it was at, and it say 11volts at about 1/4 throttle. I just read that I should be trying it at 3/4 throttle so I'll try that later. At idle it was about 10.2 and when I revved it up, it went to 11 volts. I had to jump it with my car the other day before I bought a charger and it ran the entire time without dying on me. I'm just trying to figure out what's going on, and what the first thing I should do is. I'd like to be able to ride without having to worry about charging it after I shut it off. I know it takes about 30-45mins of riding to replace the energy from starting it, so maybe there really isn't a problem because I never ride it that long. I've had scooters in the past but I've never had any issues and I've never had to charge them like I am now. Thanks in advance and sorry for the noob questions. I've been googling and I'm just kind of stuck.

If you rev it up and it only reads 11 volts, it is not charging. You can test the wire directly at the Regulator/Rectifier and see what it is putting out when revved up and at idle. Revved up it should register 13+ volts. It looks like it may just be your Regulator/Rectifier that needs to be replaced.

You can also test the stator to see if it is putting out to the R/R does your stator wires match this:

would this be in the steering column? or behind the gauge cluster? I tested it at the battery, I'll try again later to see what it's putting out at higher revs.

This is what your looking for R/R follow the wires from the Stator that has the plastic plug it will go to the R/R. There are many types of R/Rs yours maybe a little different but they have the fins on one side for cooling.

[ruckingoodtime]

If the stator was bad, it wouldn't run with a dead battery would it? Like if I jumped it. 'Cause I can jump it and it'll run forever until I shut it off. the lights are dimmer at idle but everything works, as soon as I hit the gas they light up real bright. Also, like the 2nd day I had it, the scooter blew over in a wind storm, could this have damaged anything?

Ok sounds like your stator is working so it is one of two things the battery is not holding a charge and or the R/R is not charging the battery.
So lets see if the charging system is ok, hook up the Multi Meter to the battery and start it up and rev it up some and see what the meter says. If it does not read 13+ volts the R/R is not putting out enough to keep the battery charged. If it does put out then the problem is your battery it is not holding a charge. And if you get a new one get one at least 7AMP and CCA's rated over 100, all your cheap batters are rated way under 100 CCA's that is why they are so cheap.
With Low CCA's you may get 2 good fast cranks before the battery peters out and will not turn the motor over fast enough.

battery is not that old, a couple months, and just took to autozone and they said it was good, and it charges up when I hook trickle charger to it, I've been having to do that every other day. Where would the R/R be located? The fuse also looks a little janky, so I'm going to replace the holder and the fuse as well.

[Alleyoop]

The r/r they put them anyplace but look for on the side rails like across from the carb some they do put them up front under the cowl so you just have to look for it.

I agree with Alley sounds like regulation is not letting the stator to charge battery

[ruckingoodtime]

yep I found it, along with another fuse right beside it. i'm going to take a look when I go into work.

I think I found it. I took a picture of the plug, the other plugs were just a shot I took from up through the wheel. I didn't see anything wrong.

[cyborg]

That would be it,,,,,,did you unplug it? Or was it like that all along?

[ruckingoodtime]

I unplugged it so I could see the plug... Can someone help me to find a new one?

[Guitarman]

Here you are. Check your plug and make sure this is the same one before you buy.

nope it's got 5 pins. Here's a picture of the plug
