Kiwi_Roy Posted August 4, 2010 Share Posted August 4, 2010 Do you think you will leave your innovation(s) on the bike permenantly ? No, I plan on completing my own regulator at some stage, probably this winter but in the meantime I will leave the pot in place so I can tweak it. If anyones considering doing the same here's a better way a/ 1 kOhm fixed resistor b/ 20 turn trim pot 1 k, 2 k or 5 k would do. c/ After removing enough epoxy, drill a hole through the case for the trimpot adjustment screw. d/ Remove existing trim resistor e/ Wire the trim pot and 1 k resistor in series in place of the trim resistor arrange it so when you turn the trim pot the resistance becomes less. f/ Fill over the trim pot and resistor with fresh silicone sealant. Start with the trim pot about half way, run the bike for a while then adjust it up or down a couple of turns until it's where you want it. Be patient it takes a while, could take several days to get it just right. I think it's best to mount a Volt meter where you can see it while riding, I set mine so it reads about 14.5 Volts maximum. It seems that just reving the bike is somehow different. I simply taped my multimeter to the tab on the fuel cap. The voltage varies quite a lot as you are riding, I see 12.7 to 14.5 Volts (don't tell me my 2nd Yuasa battery in 6 months is on it's way out) Link to comment Share on other sites More sharing options...
docc Posted August 4, 2010 Author Share Posted August 4, 2010 Now, admittedly, this is all quite over my head. Still, could we use a Pulse Width Modulator to approximate the advantages of the three-phase system? Link to comment Share on other sites More sharing options...

Still, could we use a Pulse Width Modulator to approximate the advantages of the three-phase system? No, sorry The power is just not available all the time, Pulse Width Modulation usually requires steady DC to work. It could be used with a 3 phase alternator. I assume you are thinking something like the power supply in a computer. The bike doesn't really need anything that complex because it has the battery that acts like a huge filter to smooth out any lumps. Here is a sketch of the waveforms, Single Phase compared to Three Phase. Hope you find it interesting. Roy Regulator 1 or 3 Phase.pdf Link to comment Share on other sites More sharing options...
