Thank you, I will look at power draw for my LEDs and follow your formula above to find the correct one for me.

Hello All, I have a snowmobile that uses a shunt type regulator to control voltage. They require a constant load (headlights) to work proper. The 2 stock bulbs are 55 watts on low with the system running 12v. Racers install another set of hand warmers, wired to high, and tape them to the...

the tps does not use any current ... if i read the wall plug directly its 5.19v dc. i have read this for a few days w/ no variation. once i plug in the tps, the wall wart is still 5.19v. then i move pos prob to tps out just to read its value. i don't know the difference of a supply vs a...

I don't mind spending some money. I'm over my head with circuits. I have wall plugs with 9v DC out. I will buy a 5v regulator. Could someone post a simple circuit for me to wire this together? Will there be other parts needed?

I need to supply the 5.0v there is no on board supply to use when setting the TPS hence the reason I'm here asking if there is a way to reduce my 5.19v "wall wart" to supply 5.0v when setting the TPS? How can I get a 5.00v DC output from a wall plug vs using a 9 volt battery? (They are always...

The tps needs to be set to tell the CDI where the throttle plates are in relation to rpm so the CDI can trigger spark at correct moment. This is all happening at 8000+ events per minute! A slight clocking (degree) of the tps makes a huge difference. I'm making a tool to set the clocking of the...

I need 5.0 v as a reference. I don't see the need for any current. Once I have the 5.0 reference then I move pos probe to tps output to read a value. Then lock the tps down. If the tps is at true 3.9 v the snowmobile will bog off idle and accelerate sluggish. If the tps is set at true 4.3v...

hey All, i have an old wall charger that is 120v AC input, 5V DC output @1 amp. when i put meter on output i get 5.19v dc. i need 5.00v dc. How can i get to 5.00v? I'm making a throttle position sensor test tool. manual is asking for 5.0v +,- 0.01 i plug power into wall, plug in TPS, use...

Jim sent me a regulator that changed to an ungrounded stator so both stator wires go directly to the regulator. The regulator has a 3rd wire out that is a 12 v DC positive. That would go to the battery and in my case I will be wireing 12v pos to fan motor, then founding fan 2nd wire to frame...

I don't have a problem with a parallel question . I have restarted my conversion and have received a different voltage regulator from Jim and have started rewiring it. I should be done this weekend or next.

reg unplugged, no bulb, 16V DC at 2700-2800 engine rpm. reg plugged in, no bulb, 16V DC at 4500 engine rpm. fan speed at 1860 rpm. I "assumed" the reg was not working when testing, the voltage would reach 15. For the above test, the voltage climbed until about 15.2 then the regulator was at...

I guess my question is, what are trophies?

I saw this on eBay: http://www.ebay.com/itm/SUPERNIGHT-120W-48V-To-12V-10A-GOLF-CART-Voltage-Reducer-Converter-Regulator-/231089881501?pt=LH_DefaultDomain_0&hash=item35ce07c19dThis is a 48V DC to 12V DC regulator (for golf carts). I didn't post this before as I thought it only for the DC side...

The voltage as it sits now is 15.2V DC at fan when the motor is at 3000 rpm. How would I test the voltage at top RPM when I have 16V caps installed? Can I overvolt them without damage? I could test RPM to 16V and reply with an rpm w/ regulator unpluged, fan on and no bulbs.

The reg is on AC side, the caps are on DC side
