I've completed 518 kms on my P-135. It's great, except for one issue (worrying issue) :

The self starter doesn't work 90% of the times. It used to work great during the first week or so, after that, it works at random.

What happens is, when I use it, the display console goes blank, and nothing happens. Then, the console gets reset (displays 188 in the speed column, full fuel, battery low indicator, etc, ie, all the parameters are set to their max value, like what happens during self check), and the console comes back. Kick start works fine.
However, the console shows a "battery low" icon once the console comes back to life after the failed electric start attempt. Now, initially the SVC guys told me my battery is low, and would get sorted out if I rode it for 5 Kms.
I rode it for 30 kms continuously, and then tried it, and the problem reappeared! The low battery icon again resurfaced.
The electric start does work sometimes though, it's completely at random.

Now, either the battery is not getting charged, or there is some internal short which is draining the battery gradually, are the reasons I could think of. Since I am a novice at bikes, I hope I get some help from you guys.

And, the bike stands in the sweltering heat of Chennai (40 deg + easily) for 6-7 hours daily. Could that have caused this problem?

I'll be giving it for its first service in a few days, hope the SVC guys atleast identify the problem.

Inputs from your side would help.
