Hi abhijeet,

You post is really informative. Don't understand why your thread is not active.

I wanted to know what is the regulator output watts on motorcycle models in india. Do you have details of the same. I want to plug an add-on on the motorcycle that draws a continuous current between 3 to 3.5 amps i.e around 45 to 50 watts. Do you think at full load the motorycycle charging system will be able to handle the additional add-on drawing 3 to 3.5 amps continuously without posing a battery discharging problem?

Also should my add-on be connected to the battery or to the regulator output side. Will connecting to the regulator output side avoid any battery discharging issue?

Regards,

If you mean a stock Indian motorcycle, it has at max around 10-15W to spare on a continuous basis! (This is on a full DC bike like P220. For a AC + DC bike, there will be not even that much to spare.)

Will the battery discharging problem be solved if I connect the add-on DC device to the regulator output side instead of connecting it to the battery?

^^ No, AC side can not spare even 5W extra. You will need to rewind to support 20W reliably for long durations. For short bursts, it can be directly connected to the battery.

abhijeet, isn't the voltage rectified and then regulated? Because I thought the output of regulator is DC. Or is it regulated and then rectified.....

I am intersted in knowing whether apart from rewinding the coils of the alternator (which requires skill) isn't there a simple way of getting additional watts for an add-on drawing 50 watts continuously. What are the options?

First it is regulated and then fed as AC to h/l and as DC to battery (after rectification).

A simple way is to save up power somewhere, like say the pilot lamps and tail lights. You can use LEDs there, then the AC side (if that side was running the bulbs) might get 15W extra to spare.

Which bike do you have and whats your purpose in saving power?

I do not want to save power but run a device that will consume 50 watts alongwith the existing load of the motorcycle. I feel that if I connect it to the rectifier end then there should be no battery discharging problem but perhaps the battery charging rate will be slowed (which IMO is ok). But if I connect the device to the battery then the battery will surely discharge quickly due to the power consumed by the device.

The battery will not drain yes, but the device will not run either. AC side can simply not supply 50W!
