I have a two year warranty on the vehicle, but now I can't stop myself from doing some modifications. I have recently added another horn (same as stock type) and now its a pair of horns. Earlier I had decided to install a windtone horn but Dropped the idea as it would not suite to an Activa.
The way to!!! Do you have a relay installed for the horns? Why did you not look at heavier horns like the Roots - Minisonic or similar?
I agree with you on windtones. I have seen people haveing windtones on their Access / Active. Mostly those are the school chaps using the bike for tuition centres & somehow did not appeal to me due to my age factor.
I am using 55\60 (800's stock bulb) in my access. I haven't faced any problems till now. The only issue is the bulb is bit dim at idle speed.
I have a central locking too, I haven't faced any issue with battery.
I also need a suggestion, the tail lamp bulb frequently burns away, any particular reason ?
Good Varun. My wife's Kinetic Honda's lighting is also insufficient sometimes. All I could opt for is only a 35W Halogen bulb upgrade as the holder size is scooter type and 35W was the maximum available with the pin type holders.
Is your central locking similar to the car's - I mean, electical actuator type?
Please check the voltage output at the Voltage regulator. If the RR unit is throwing out higher & unregulated voltage you can observe this. Is the speedo bulb doing good in your setup. If nothing works, you can use a RR unit of a Pulsar / Bajaj Rickshaw (that version which goes for 2 headlamp type). They are easy to wire up and rugged for higher current applications. In your case you are loading the regulator by about 85 % more that what it is designed for. Such 85% operation margins are never seen on Electronic circuits.
I think the bulb is getting less power (voltage) Due to the use of 55/60 bulb. Someday please check the voltage at the rear bulb holder at low(idle) RPM. The bulb fuses away due to low or flactuating voltage. Why don't you replace the bulbs with some custom LED.
With lesser Voltage there is no reason that a filament bulb will fail. A 12V bulb will outrun the vehicle itself if used on a 6V electricals bike. The filament burning off could be due to improper voltage after the regulator. BTW there is a 2 filament LED bulb conversion available on ebay.
The main reason I dint replace with LED's is because it has 2 filaments. I also tried to to get a led (ready made with holder) but it has a single connection (single filament).
Wont a strip of LED do the job. You are the more experienced in such DIYs. Thats why I wanted to know if you gave a thought. Even before going the LED way I would highly recomment replacing the RR unit.
For Info: In 2/3 wheelers the device is called an RR unit - Rectifier Regulator unit. The unregulated AC from the alternator is fed into the RR unit. The RR unit has 2 outputs. One of them delivers a regulated 12V AC for the headlamps & tail lamps. The other output channel is a regulated DC for charging the battery. I guess, the AC regulator part could have got affected due to loading it with 60 W (Head lamp) + 6W (Tail lamp) + 6W (2 X 3W) (Speedo bulbs). So please check the AC output first to sort this out.
The other Alternative is to use a Rectifier unit from a Bajaj Diesel Rickshaw and convert all AC to DC and feed to the battery. You can have all the lights operated from the battery itself. This way you can operate the HL at its full performance & get rid of the filament burning problem. You will have to take care that the HL goes off while cranking, just to protect the battery from overload while starting the scooter with HL on. You can see this happen in all Tata cars. Might be in other cars too, but at least not seen on my dad's Ikon or Uncle's Accent.
Hope this is enough input till the New year holidays. Enjoy Modding your scooters.
