Still not Charging back to round1 By damin69 (Read 13,591 times)

Hey Todd - that fancy new regulator arrive today?

[Cruiser]

Well, I might just be done fooling around with the charging system on my YY250T. Here's a rundown of my messin' around:

1. Replaced all R/R output and ground wires with 12 guage wire.
2. Replaced OEM radiator fan with a more efficient fan. 2 amp savings.
3. Upgraded to LED bulbs.
4. Selected the best of my 3 R/R's and mounted a 80mm cooling fan on it. Ended up using the original R/R.
5. Replaced blocking diode with a relay which works with the key.
6. Replaced OEM battery with 12ah 230cca AGM.
7. Installed a dash mounted LED digital volt meter to see how everything's working.

Now charging is at a 13.6 volt minimum @ 4000rpm with both HID 35 watt headlights on, radiator fan on, and of course electric fuel pump on. With headlights off, it will run up to about 14.7 volts. Have to go on a long road trip to see if the R/R overheats although it seemed to run cool while I did my prelim testing. I'm happy with the apparent ability to really regulate the charging voltage within the design limits as stated in the shop manuals. It will be interesting to see how things hold up.

Cruiser, That is Awesome. I would be extactic if I could be stable at over 13.5 volts.....

I am going to give this bad boy a try this week. Will let you all know how it goes.
Don not let the size fool you. Even though it is smaller it actually weights more than the Chinese stock RR. You can tell just by the feel that it is made of quality parts. I can not wait to get this on and give it a try. I hope I have enough time after work tomorrow to get it installed.



I will continue to put up pictures as I go here www.pbase.com/damin69/oregon_motorcycle_parts

Pretty sad that it takes all that just to finally arrive at some 'normal' charging specs. Hoping Damin's new RR from that shop will provide some more punch with stock equipment.

The other variable is the R/R. No two seem to have the same output. Maybe the one Todd is checking out will be more consistent.

I took mine to work today and had a surprise trip to the south side of town. The temp was in the 90's and the fan stayed on A LOT. I drove 55-60MPH most of the way home and the engine temp was up around 160-180 the entire time. I figure if it wasn't charging well enough THIS would be the ultimate test.

Got home and cranked over just fine. Still showing 13.5 volts ALL THE TIME.

Does anyone think that if I moved the tap point of my volt meter from the front (currently tied in to what used to power "motorcycle sound" ) to the back near the R/R that I should get a higher reading than 13½ VDC?

[Cruiser]

My voltmeter is attached to the hot wire for the alarm system up front. The actual voltage at the battery is about .3 volts higher. So if you get 13.5 volts with that hookup, you most likely are closer to 14 volts at the R/R. That reading you have is excellent and is good especially for AGM batteries that are more sensitive to overcharging.

OK GUYS. I got the OMP RR put on tonight. Let me say PRELIM is Great.

Please see other thread for more detail.

Oh yeah.. I should mention with this RR it is the First time since I have had this scooter. I am over 14 VOLTS Ever....... ;D
