When I connect it directly with the battery it is working but couldnt check it in road condition as of now. Currently my scooter is without headlight. |
You are about to change something out of stock condtion which is actually not meant for it. So without moding the electricals, you will end up with battery issues.
If you do so, expect a max backup of 20 mins. So plan your routes accordingly. Quote:

Look a the ac/dc converter mentioned.
You should be able to get from any car market. |
In addition to the RR, you need to unground one of the light coils within the stator coil which will be grounded by default. You will not get the full output from the coils until its ungrounded. Quote:

The only fly in the ointment is that they require DC to operate(battery is DC) though inside the ballast it is converted to AC. I doubt if run of the mill converter products can supply the 8 to 9 amps required by the ballast for the first minute. Do check the rms ampere capacity of the DC to AC converter. It should be at least 10 amps. |
Hi Doc, you have forgotten one thing that these AC lighting bikes are not designed to support even a 35W halogen as the charging rates are too low to compansate the battery drain. Theoritically 35W HID will consume 2.9A but in real terms its taking 3-3.5A. Evenif its 3.5A, as per theory it should give a backup of nearly 2hrs. But considering the load at the time of cold start, starter motor etc. the backup time will be badly affected. You can see on many forums those who have connected the HID to the battery without any mods to their AC lighting bikes are facing battery issues.
Two years back before converting my bike to full DC, I was also in the same assumption that it should support a HID without any mods. My 2004 Pulsar was running with one month old a 9AH Amaron, sporting with a 90/100W halogen with the help of a rewinded stator coil. When I installed the HID, I got a max backup of 20-30 mins. on highway driving. I've put a bridge rectfier on the lighting out to boost the charging rates but to no avail. Everyday I was ending with a flat battery. The stock RR was pumping 3.5A @3K rpm which was found to inadequate. Later I've bypassed the lighting coil to a higher capacity RR and now the charging rates have improved to a decent rate 8A @ 3k and till date am with the same battery with no issues.
BTW, not even a sigle full dc bike is having 10A charging rates. The best among the desi bikes are Y-R15 has got a charging rate of 7A (IIRC) which is having a puny 3.5AH battery to support 2X35W halogens by stock. And there are folks excelling with 55/60W on highways but on city drives they too suffer battery issues.
