Yeah, what do you want to use it for?

Good RR Unit for Pulsar 150

Hi Everyone, This is Sajan, been a frequent reader of this thread as I am also interested in modding my P's lighting. I have done the coil rewinding and the output was amazing, was running on a 90/100 halogen which gives me enough brightnes and respect from the oncoming traffics too. Last week I have got a HID kit, installed, working fine. Perfomance is another story that I will take you to later on.

Now switching to HID, my stock bulb circuit is idle and the power is from the battery but its not holding more than an hour. So I need to change the RR unit to improve the battery charging. I tried to connect a bridge rectifier to the stock bulb supply it seems getting shorted as if the current too high to handle by the rectifier. SO i am looking for a good high watt RR unit. Somebody can help?

I invite everyone who are already switched to HID and how is managing the battery charging issues? Any idea of swappin the stock RR unit with Shoguns or Fiero/ Bullets?

The Zma RR unit can be used.

Thanks Abhi for the help and I will enquire about it get back here. Currently I am on research of High Capacity battery charger unit something like used in diesel 3 wheelers which is a single phase RR and I hope I can solve it by this.

Dude, there is some limitations for the battery to withstand. It doesn't mean u put a big charger the battery can charge heavily. Better stick to 2 wheelers RR unit which will have a regulator to charge the battery sufficiently for 2 wheeler battery.

Well putting ZMA RR Unit might help increasing the charge rate but there is no coil (AC) output provided from ZMA's RR Unit as ZMA by stock is complete DC.

BTW which bike are u riding and how can u mount 2 bulbs ??

Dude, he is only putting a higher capacity charger. He will use it with his custom 100/90 stator coil. This stator coil has one coil only, which can be used for DC with any capable RR unit, incl Zma.

His bike is P150 DTSi UGI.

I differ Abhi at least in my case as ZMA RR wont suit as its a 3 phase one, defnitly we will get some output but I doubt its not capable of extracting full juice out of a single phase alternator. ZMA's contribution is from 3 phase so defnetly a powerful one and considering the cost factors, ZMA will be the last option. Yday I went to the junk yard to get an RR unit of 3 wheelers but wasted time, zero availability. May be next time hopefully. I found some fine projectors really seductive but its nearly 4-5K for the whole assy and they dont've the lens alone.

Sreeni, my stock RR is capable of giving 3.4A @4K but its not enough to feed my HID, the meter shows -1A after the HID stablization time. So defnitly need a higher ratting charger. Am commuting at night at least 1hr, which is not fully supporting with the existing setup, batt dies within 40mins and next morning I've kick start. Ofcourse, my battery is getting fried but before getting a new one, I have to sort out this. Every RR unit should have AC input to make a DC out but in my case Pulsar is only single phase. My HID is a H/L with the solenoid, so no need of two bulb. Did I say that? I use an aux lamp to ride after the batt drains which is mounted on the crash guard.

Well, I thought Zma has a single phase RR unit. If it is really 3 phase, then its not suitable!

Why install a new ckt?why cant the headlight, Tail lamp be connected to existing DC o/p?

@ Rahul

The switch(spdt) connected in ur ckt diag needs to on/off when starting(to use elec. starter) and opposite when running headlight on DC?



P.S. what does UG3 stands for?

They can be conencted directly to battery. But the battery ckt is not powerful enough to run them together. So, it needs power from the AC circuit which is what we have done!

UG3 means Pulsar Upgrade 3. (Basically the Pulsars with digital speedo.)

This seems to be a great setup, Nice Info Abhi

So basically the tapping is done to the coil and using a custom rectifier the same is fed to the headlight? in that case why there is the problem of bat discharging as mentioned in some of the posts? since AFAI understand the bat is not in pic. then.

and in such a case what hapens when the engine is not running?

The custom RR unit feeds the battery and the battery feeds the h/l. This is not the same as coil feeding the h/l. If the engine is not running, the batt discharges slowly!

@ Abhijeet

Im lost dude!!!

Btw below pics illustrate my understanding so far. Do point out wherever im wrong.

Actually there are two coils in the bike. Both are connected to the RR unit. The RR unit gives 2 output, one to battery (DC) and one to h/l (AC). We take this AC o/p from RR unit to h/l, convert it to DC using the custom RR unit and connect this one too to the battery. Now, battery has 2 power sources. Now, we connect the h/l wire from RR unit AC output to battery. Got it?

The DPDT switch and the relay is needed only for P180UGIII, else the BCU does not function properly. Its connection is given in the first page.

Anyways tell me what is it that you want to do and which bike?
