I have a push-button switch rated at
3 amps @ 125vAC
which I want to use in a 12v DC application (my motorcycle).
((on ground line under continuous use {headlight}))
Does the AC rating translate as
3 amp for 125v AC hence 375 watts
375 watts for 60v AC hence 6.25 amps
or
375...
So all you guys are telling me that my design won't work.
I was going to get a bunch of these Peltiers and wire them into my motorcycle vest and be cool riding down the road in the summer.
I just got a peltier (12v 60w TEC1-12706) and tried to check it out.
I have never had a peltier before and don't really know how they work.
Mine has a red and black lead so I connected them accordingly to a 12v DC trickle charger.
BOTH SIDES got hot (very hot right away).
I thought a...
Wow - excellent find - I looked for a cheap PWM for 12vDC and couldn't find one. So I designed my electric motorcycle clothes with multiple circuits - each with a different wattage - so I just plug in whatever circuit is appropriate for that day's weather.
If I had this PWM when I started I...
Yeah, they have a metal tab with a mounting hole.
So my plan is to attach the wire from the Flasher Relay to one anode and the wire from the Brake Switch to the other anode. Then simply run the wire from the Bulb to the common cathode.
They are 10 amp diodes (in a dual package) and I will...
I found a Schottkey diode for 85 cents that is Dual packaged
It is 10 amps, 100 volts.
It has 3 leads: 2 IN and 1 OUT
I assume that means 10amp diode on EACH lead IN??
This will make wiring easier and smaller (I think).
As only 1 diode would be working at any given time, this could help...
I assume when a diode dies, that it won't conduct current in either direction ??
These diodes will be located under my passenger seat with lots of other wires and connectors. I would typically wrap them heavily with electricians tape for insulation. However, with the heat dissipation issue...
I have found (so far) 3 diodes that meet my basic specs of 3+ amps and 15+ volts.
However, I have no idea what the differences between them are:
Schottkey diode
10 amp, 100 PIV for 85cents each
Rectifier diode
6 amp, 200 volts at 90cents for two
High-Voltage UltraFast Rectifier
15A...
I assume the heat generated is from the voltage drop across the diode - when the diode is conducting current.
If I understand your wiring diagram correctly - the diodes will only conduct current when the light is either flashing or braking. Both are short lived events. So I am just going to...
Very good to know - the slight dimming of my light is (I assume) from the voltage drop of the diode. So if I find a diode with 100volt PIV or 50volt PIV they will both work the same in my application.
Excellent - our diagrams are topologically the same although mine sure doesn't look as good as yours.
Back to the diodes I have to buy, if you please:
? the voltage on a diode is the Maximum it can prevent from flowing 'backwards' ??
so, in my case, anything over 15 volts will...
Thanks to you, I THINK I have a diagram that will work.
I have seen posts on this website with wiring diagrams - how do I do that ?
Then I could post what I think will work and you could check it.
In words: four 5 amp diodes, one each on wires from brake switch to each turn signal, and...
In the USA brake lights do have to be red. I replaced all 4 of the original Turn Signals on my bike with larger, double-sided Turn Signals. The backs are red and the fronts are amber. It is legal to have Turn Signals be red.
I have already installed a set of red LEDs as additional brake...
Thanks, vk6kro, now I am confused on a higher level - the definition of progress.
I forgot about the front Turn Signals - on most bikes they are not also running lights. But I converted mine so they are both running lights and flasher ((so I have 4 running and 4 flashers)).
Anyway that...
