Still not Charging back to round1 By damin69 (Read 13,599 times)

Thanks Zug that would be a huge help to.

How do I know what the temp is getting up to without gauge to go by?

Well *I* have bad news, at least as far as I'm concerned. On the other forum there is a "MC-54/MC54B Parts Cross Reference List" and on page 4 Big Guy points to a stator on partsforchinesescooter.com that is supposedly for the 54B scooter. I can't fault Big Guy because even the site says it's for the linhai engine. The problem is that the thing is quite a bit smaller than the old one.

Old shaft size is 41.5mm and the new one only has a shaft size of 35mm.
Old one has an overall size of 104mm and new one only has 93.5mm.

I found one on ebay that says it's physically about the same size but it only has 4 wires coming out of it where my old one has 5.

I didn't want to crack my engine until I had parts to fix it with and now I don't want to put it back together with bad parts. The old stator has burned coils so I'm sure that's my trouble.

What should I do?

I found this one that SAYS it's specifically for the roketa 250B but I'm a little leery without specific measurements.

I put it back together and it's still not charging with the new regulator, so I'm 100% sure the stator is bad. <sigh>

I found that parts for chinese scooters DOES have the right one so I'm hoping that they will swap me out as they're the same price:

I read back thru the forums and the same things came up for the cause of the fan to come on too early.
1) bad thermoswitch
2) loose wire/connector
3)corroded switch (water temp switch-see pic)

some of these things can also cause irratic/incorrect gauge readings.

Sorry, being lazy since Im so tired and not loading into photobucket.

That's the one that Big Guy pointed to and the one I ordered. Most of the ones I see listed don't tell the measurements.

Hey Roy, the first stator you referenced above is definitely not for your scoot if it fits the CfMoto V3/V5 which is in in the compatibility listing in the description.

Ok well I got stuck in Jury Duty all day. But I did get a chance to work on scooter tonight. I got the Low volume fans mounted and I did get the new fan in but I have to take it out tomorrow and modify the housing as the fan is hitting it when it comes on. Oh well that will only take about an hour to do. I did find out something else that when my RR get warm my voltage drops. I am going to mount a cooling fan on the Regulator to see if that does not help out a bit.

Here are some pics of my Low volume fans mounted. I have them on a switch so I can turn them on and off.

Nice work, Todd. So I guess the Silicone intakes fan was the same size as the OEM? I already installed an 80mm fan on my regulator.



I drilled 4 small holes in the heatsink fins and ran the black fan wire to the regulator green and the red fan wire to the regulator black. The regulator to the left is the smaller (I think used mainly for 150cc) unit that works with our scoots. You can actually fit the 80mm fan on that too if necessary.

[damin69]

Not quite the same size had to do a bit of modifying. I will post pictures later I Put a cooling fan on my Regulator also. I did not get pictures of the modded main fan lets just say I cut the round part off and used the houseing that came with the new fan.

By the way. I am still not charging. Everything went great started all day got back home and not enough juice to start it.

I did notice last night when my Regulator gets hot the output voltage drops down below 10 volts. That was the reason for putting the cooling fan on. After I put the cooling fan on the voltage always stayed above 12.7 volts.. Atleast during Testing. The volt meter should be here next week then I can monitor it better... Uggg.. This is so damn frustrating. 1 step forward 2 steps back.....

Ok on to the Pictures for the Regulator Fan and mount.








Only had to make one little notch in the body to get it to mount properly. Now this is a 120mm fan so it is a bit bigger than the 80mm fans.

[damin69]

Well got hold of Evo and they are sending me a New Regulator so will give that a try. Maybe like said one before 3rd may be a charm.

[damin69]

Funny. They send me an order invoice showing 12 Volt Regulator 7amp. What the heck are they thinking? Heck Going through the schematic and adding up just the draw on the bulbs not including the clock or the Radiator Fan the scooter draws over 11.69 amps on bulbs alone. Add in another 5.8ish for the stock fan. That is 17.49 amps. DAMN no wonder them chinese regulators are over heating. That is nuts. I figure I am at about 8.04 amps draw before the cooling fan. Man where else can I cut. Maybe I should dissconnect 1 headlight that would drop about 2.9 amps total draw. Hmm It might be worth a try. :-(

I have been email back and forth with Tony a bit. He is working on a Regulator/Rectifier to possibly fix our issue but will be a bit of time yet. He may have a option that will work for us in the mean time. :-)

[damin69]

Well guys I will let you know how it goes. I just got an email back from Tony I am going to be a bit of a Test Monkey for him on his VRRPM3H regulator and wire it up for my scooter. "This is also the highest amperage unit I carry and should last forever on a scooter.." Per Tony's quote. www.oregonmotorcycleparts.com/VRRPM.html


I will let you all know how this goes... and keep you all up to date.
