Convert AC/DC bike to ALL DC.

My ride is mostly in moderate city traffic.I'll not use both HID & Horn simultaneously so I think as you said UG4RR + Ungrounded coil is enough for me.

You have a CB twister ?
Then,UG4 RR should be good.

Open the LH Magneto/coil cover and post a picture of it so that more members can help you out.

I found this link on how to rewind a stator RFS STator Rewind How To

If i were to rewind my stator on my own how many turns per pole would i need and which gauge ? 19? my bike is the cbz classic

This is my CB Twister magneto coil

mate,thats a 12 pole stator!!!you have lots of groung to play with.i would suggest get it rewinded with 17 awg wire as much as you can perpole and finish it by ape rr,trust me you will be getting 10+ amps from that setup.

if you want to use ug 4 rr then just add and see it would be equal to what a ug 4 provides.

but still try for the first option. even witha puny battery that setup will rock.

12 pole stator in a 110cc bike !!!wow that's just awesome.
Don't go for a UG4 RR instead go for APE RR.

But before going for ape rr note that without battery it would provide high voltage which is good enough to burn all electrical parts as i heard .

i am sorry but what kind of pointer is that/. first of all you are converting it to full dc and after that you are telling without batt it will produce high voltage. do you think that ug 4 rr dc conversion or in that matter any dc rr will provide stable dc voltage if you use without the battery in the circuit?

[rajaselvam_1987]

i measured the voltage on battery when engine of condition is shows 12.35V
when engine on it shown 13.5v
at a half throttle it shown 14.5v and stable upto full throttle

I removed red wire from battery and connected to red terminal of multimeter & connected black terminal of multimeter to battery '+'. At a half throttle it shown .65 amps. Is this correct way to measure the amps.
But i don know exactly how to measure amps

but When i'm driving my bike at 50+ speed the horn is not crying.

What is the capacity of your battery ?(2.5ah/4ah/5ah/7ah.....)
That is the correct way to measure amps.
At full throttle with stock RR it will give around 0.9amps to 1 amps.

Don't rewind that coil if you are not upgrading your bulb to 55/60w.
Rewind only if going for higher wattage bulbs.

As for now un-ground the coils and use a Ape RR so that if you want to rewind in future you will not have to buy another RR.
If you use UG4 rr now then you will need to buy ape RR when you rewind.

[rajaselvam_1987]

Can i use this stock coil without rewinding only by just un-ground the coil and connect it directly to green wire and finish with Ape or UG4RR as said in the first page of forum.
Already white wire is directly connected to coil.
If i do like this how much amps i can get

My battery is 3ah.
But how to measure the amps without battery that means the output amps of RR
Now i'm using 35w HID without any prob on highways at a speed 50+ but inside the city i can't.Even can't able to use Roots Horn continuously at first two beeps its works good but after that i have to wait for 100mtrs to beep again else it's crying.
Inside city i use 35w Halogen on AC output

You measure amps with the ammeter/digital multi-meter in series.
The red wire of RR goes to red wire of ammeter/digital multi-meter then the black wire of meter goes to positive terminal of battery.
(anyway works but only sign changes on display)

From some previous post's what i found is ape rr without battery produce high voltage & it also got fused . That's the point i was telling , so if by any means there is problem in battery & you removed it then no point to run bike without battery if you used ape rr for DC conversion , sorry if i said something wrong .

hi doctor,

But before going for ape rr note that without battery it would provide high voltage which is good enough to burn all electrical parts as i heard .

He heard it from me. here is the scenario.
I have Unicorn, and in stock electrical condition with stock RR, I can start the vehicle without battery by using kickstarter. As you know Unicorn has no separate ignition coil and it draws current from battery or RR for the engine to start. Same is the case with Ambition.
I rewinded the coil and used APE RR to make my Unicorn FULL DC.
Now with the battery connected I am getting voltage of max 14.1V (no problem here). I tried to measure the open circuit voltage of APE RR, so I disconnected the battery and tried to start the bike, but in vain. So I connected the battery again but disconnected the APE RR from the battery(yellow wire) and measured the voltage across the yellow wire. And I got 19volts.In this case bike is drawing current from battery for ignition.
SO the result is
Using APE RR and without battery Unicorn cannot start. may be the same with bikes using current from battery/RR for ignition.
But with Pulsar UG4 RR the bike started without battery by using kickstart. So the bike is drawing current from UG4's RR for ignition which is by the way 13.2 volts. As I've already said with stock RR also the bike started without battery.
I cannot draw conclusions, but I can say the APE RR is just a heavy duty and efficient charger and provides no useful current to start the bike for bikes like Unicorn's ignition.

As discussed earlier in the forum ,
Ape RR senses the presence of battery and then only its pumps current whereas UG4 rr pumps current irrespective of presence the battery.

I may be wrong here but from other's experiences I have came to this conclusion.
I haven't personally tested this behavior of different RRs.

Let's see what other GURUS have to say about this.
