Convert AC/DC bike to ALL DC.

Well even i was shocked... but i think i read it wrong as i disconnected my battery ... im guessing it should be in series with my battery ? again this is a cheap meter its quite likely wrong.. I was reading on bcmtouring where few users used a 7ah ups battery in their pulsars with no issues. What is the correct way of checking the amp output ?

It must be checked in series with the battery.

It must be checked in series with the battery.

well then i get some really low readings.. like 0.5 amps

[shoeb2015]

0.5 amps is sufficient to charge a puny 2.5amp battery !!!
At full throttle you should get around 0.9 to 1 amps.
Your stock RR is capable of 1 amp max.

Yup that sounds about right. whats the output of a splendor/passion+ rr . and whats the output of a pulsar rr coupled with the same bikes without a coil rewind?

Max DC output of a stock passion+/splendor+ RR is 1 amp.
UG4 RR can push up-to 5 amps DC.

But what I was really wondering is can my stock coil push out enough power. I read the ratings. in Electrical Modification on Hero Honda Passion tread. I wanted to know if he was getting 5 amps without rewinding his coil.

[rajaselvam_1987]

is your bike fully stock? what's the power rating of your horn?
suggested mods (any one will do)
* higher amp battery (5 or 7)
* rewind + RR change

Ya my bike is fully stock.
Backside of the Horn mentioned 12v/4A

@ Abhijeet
How can his electricals be fully stock when he is usin a HID and a roots horn ?

my electrical is still fully stock bcz the HID is HID+Halo combo.The halogen is working from RR's AC output.

@rajaselvam_1987
35 watt hid is draining the battery.
Option you have for this issue are.
Option 1.(Dose'nt last long if only night riding done)
New 5/7 Amp-hour battery

My drive is not always in night & also inside city i never use HID.

Option 2 (Recommended)
New Pulsar UG4 RR + Coil un-grounding + New 5/7 Amp-hour battery
Cost 450 + Free if you are doing it + Rs.1300-1500/-

If i do the UG4 RR + Coil UN-grounding without changing the battery will it work effective

for those of you, following this thread regularly, and those not aware please turn back a few pages, i worked this saturday on my bike with lots of free time and patience and finally solved my problem. it was a broken wire and an improper ground connection. now everything is ok as earlier.

in the process, i learnt a few things, like my mechanic gave me a free UG4 RR to try and check its output

• Pulsar UG4 RR can also be used in place of APE RR for DC conversion and it can give an output of 5.5 Amps with rewinded coil. same output as that of APE RR on my bike. it is cheaper also.
• if the black ground wire of APE RR is gounded to its own body and the whole thing mounted to chasis, it may create some problem, so better to ground it little bit away from APE RR.

Glad to hear that you have solved the issues

I was quite sure of that it could be some wiring issue, else it should work fine as like others it should be fine with the setup. Yes Black wire has to be treated well get proper grounding else, the manufacturer might have saved it within the RR body only.

UG4 RR is capable of giving out 5.5A? Well thats a good news for all budget minded moders. Now I uderstood some of the stock UG4s are running on a 55/60W halo without any batt issues.

if you're getting nearly 3A with UG4 RR at idling then even a 5A battery would be enough for a 55/60w h/l & 4A horn used simultaneously at 2000RPM & the horn won't be crying..
if the charging rate is not good enough even with the UG4 RR then upgrade to a 7 or 9Ah battery. Hope this helps

I think the UG4 RR + ungrounded coil will be enough.
BTW, what's your ride?

I am currently using Pulsar UG4 RR on my rewinded coil of Unicorn for testing purpose and its working very well. The 55/60w bulb is glowing very better and also the horn is louder than with the APE RR.
Pulsar UG4 RR's open ckt voltage is b/w 13~14 volts and very much suited in case there is no battery in the vehicle. where as APE RR's open ckt voltage is 19v and when connected to the battery only I am getting regulated 14.1 volts, which means without battery I cannot use APE RR to start the vehicle without destroying the electricals, also my unicorn wont start without battery if APE RR is used.
But there is one problem. The Pulsar UG4 RR is getting very hot when I ride with the lights on for about half an hour. What can be done here? Another Pulsar UG4 RR in parallel or installing a good heatsink?
How much will the Yamaha FZ's RR cost?

I am doing the same, black wire to the same bolt used to mount the APE RR to the chassis/frame. no problem till now. Do I need to change this setup?

sajjt i had got the rewinding but still the charging amps are only 5 and i want 8 amps so my mechanic said me to change the magnet then u will get the 8 amps charging rate
is that right....
if it is right then which magnet will fit in my scooty pep+

thanksss.....

Sorry, dont've much things to help u in this, its too much for a puny machine. As I said earlier its not only the coil which determines the output, there r other components like magnet power, stator core properties, engine rpm etc. U can't alter all these to some extent only beyond that u'll end up with a messed up engine. If u r still adament to go for then try with Pulsar magnet if its available separately else, u may have to go for the entire flywheel but I guess it wont accommodate within the case and it may disturb the timing by changing the location of the pulse coil. Don't rely on grease monkeys in this too much in electricals as non of these are qualified to give u a authentic advice nor me

So its better be content with what u've right now. This is more than enough to screw a high beam rider

pulsar RR is getting hot because for its heat sink to work it has to be solidly bolted to chasis

and regarding the black wire see below.

Yes Black wire has to be treated well get proper grounding else, the manufacturer might have saved it within the RR body only.

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.
