Modified Ducati Regulator

is that true only a trickle charge? I thought it provided 90 watts of power.

I would estimate The standard Variatronic stator would only supply approx 20-25 watts dc, like coaster says a trickle charge.
The standard stator is AC biased most of the voltage produced is on the AC side of the system not the dc tap on coil 3.

Sorry if this is a little off topic. Modified Ducati Regulator

I cannot comment on fitting Caps to variotronic but ran both of mine running weasels with caps. I found it the only way to get a constant 13.5 volts DC. Without a cap across + and ground I only had 6 ish volts lights on. The cap will smooth out any drops in voltage but in no way replace a battery. I have battery's on both now but the caps are still connected. I did a Wassel conversion for a mate who didn't want to change or mess with his key switch to isolate the battery so I fitted a simple 4 pole auto relay that connected the battery when he turned on his lights. All because he had a cam lam fuel led that could be on all the time if he parked up with low fuel. The relay would not energise with the engine running till I added the cap.

Sorry to jump in on this thread,but are you saying you can use a capacitor insted of a battery?
I am fitting a Varitronic to my Scoot and would like to run DC,but dont want a battery.So what size capacitor would I need,and would I just connect all the 12v positive wires to the red lead?

That depends on what you want to run off the DC supply, the Varitronic only provides a trickle charge for DC. That might be sufficient for charging a phone or sat nav but won't power anything with a higher current demand such as air horns or spot lights.

I need a dc supply to run an egt gauge,nothing else.
