How to charge the lanzar 1.6 capacitor
typically you can charge or discharge large capacitors using a resistor. Not just any resistor will do. You will need one with high-enough resistance and wattage ratings or you'll burn up the resistor. I would use a 1/2W, 4.7kohm or a 1W, 1kohm. These are minimum values and you can use a slightly higher resistance but it will take longer to charge/discharge.
To charge, connect the positive terminal, then hold the resistor between the ground wire and the ground terminal for 30-60 seconds. Then connect the ground terminal. To discharge, disconnect both terminals, then hold the resistor across the terminals (do not reconnect terminals without charging). In either case, you can use your fingers to hold the resistor as DC will not shock you, but if the resistor gets hot it will burn you. I use needle-nose pliers to hold the resistor (just in case). Just be careful not to short the resistor leads or terminals with the pliers.
Explanation: For a standard cap 1 - 2 farads, the discharge voltage is up to 20V so we'll figure off of that. I would use at least a 1/2 watt resistor, a 1 watt could be safer, depending on the value. For a 1 watt, the current can be no more than .05A at 20V. For a 1/2 watt, only .025A. Let's say .04A and .02A, respectively. Ohms = Volts / Amps, so 20V / .04A gives us 500ohms. Double that to be safe (avoid overheating) and it's 1kohm. Same process for the 1/2W version will be 2kohm, but it's not as hefty, so I would recommend 4.7kohm.
