Actually, I'm still a little puzzled over this. Not only all four motors, but the controller has also burnt which was hidden at the base of the frame (near the fuse box under the dashboard close to the steering wheel).
It appears that I need to replace the whole system. Can someone suggest me a good system and it's cost? I've visited chah sultan and they all carry the same systems. 'ToYo' [Complete set for Rs. 600] and 'Defense' [Rs. 850]. Asking 250 for installation. Both systems are chinese. Surprisingly enough, the guy in blue area (at the back of citibank) was asking Rs. 2000 for 'ToYo' complete set and presenting a 'Royal Defense' [complete set for Rs. 2800] which he claimed was Thai made.
Guidance would be highly appreciated. Thanks.
