ZMA/R has got a 3 phase alternator and 7AH batt (IIRC) so, swapping with a 3 phase RR is not a good idea, it may work with that though, and cost wise also its on the higher side. If u r worried about the over charging rates then, ZMA/R has got a 200+W alternator which can pump out not less than 16A which is not at all required for ur case and coupling it with a single phase alternator u can't dream of getting such a whopping current rate.

Philips and Osram falling under premium range and its hard to get in single piece. Consider some other brand coming with 1 year warranty for ur peace of mind.

FIY, I've'nt done this on a smaller CC engine so far, its totally depends on the stator core, magnet power, quality of the elements used, number of turns and finally the neatness in winding. Sometimes it mat turn out to be a failure, one of our fellow member once tried to rewind on a Y Crux with APE RR which turned out to be a total failure as the pumping rates were lower than the stock. One more, rewinding on a smaller CC four stroke engine is overloading, u may loose some spirited sprints on signals.

I have done full dc conversion on many 150cc bikes but never on a 100cc

I am free this week so I want to experiment on installing a Hid(I have a spare hid left from previous mod)
Also I will be comparing the charging rates of stock and re-wounded coil.

4.Can anyone provide me the part no. of pulsar 180 ug4rr or any distinct feature of it ?

Today meet some garage mechanic's & they don't have any idea about ug3 / ug4 , they told the old pulsars are ac+dc while new one's are complete dc so it might be called as ug4 . The pulsar hold's a 9 ah battery as they said , so as you mentioned a current of 4/5 amp from rr is ok for 9 ah battery but isn't it gonna frying machine for a 5/6 ah battery ? What charging current is excepted for a 5/6 ah battery ?

Is in this free week you gonna do the mod on some 100 cc bike ?
Please after you DIY put the charging rates details .

4. And you got the pulsar ug4 rr give its part no. details to me too .

Boost in battery charge is required to compensate the drain from the battery without much delay as it may get fried with insufficient charging rates. If the demand is 6A and that will be shared from Alt+battery and during this time if the battery level is going low, the RR will charge the battery if there's extra current available at the alternator if its not there that time, when the alternator is free from load, it will charge it. When the battery is full, it wont take more than 1A and the RR will become on trickle mode charging state.

U don't've to spent time with mechanics, instead go straight away to the Bajaj spares and ask for P150/180 UG4 RR, if they couldn't follow u, tell them the battery charger for UG4. Part No. is not a must as they will check with the Service manual and get that.

In the mean time till i get the RR ,I converted the rear tail lamp to led.
Yet to convert pilot lamps,cluster,indicators to led to .
reduce the load on batt.

@ above all
I request you capture the wiring diagram with a good camera at high res.
(need it for reference so that minimal changes can be done to the stock wiring).

I have to upgrade to a 7/9ah battery so support hid.
What do i do with it ?
Sell it off or make a emergency light out of it or something else ?

& can you please provide some rough connection diagram if there it need to remove the ground wire & pulse generator as in first post ac to dc conversion universal thread .



Bro next time i will try to snap as clear as i can . Is there you going to unground the alternator grounded wire , & making some modifications with stock pulse generator . rr connection ? or just only replacing stock rr with pulsar ug4 rr ?



A local made battery on resale won't give you much price but instead of it if you make some switches to on stock rr & this local battery with a aux/ another light , it would be good in emergency if modified circuits burn out .

The old RR will be remaining there but all the connections will be removed.

Whats the cap of your batt ?
Are you planning any hid setup or just full dc conversion ?
I have decided that I will not install hid as soon as I am on full dc,Instead I will use 35w halo.
First I will test the reliability of the setup for at-least two weeks,If everything is good then I ll install Hid w/projector.

Where do you live BTW ?
