I bought this same zapper from Harbor Freight today and tested it before I made any mods. The grid holds power and makes a big spark even after the button is released and I touch a screwdriver across the grid. After clipping the resistor in mine the spark is about 3 times bigger and a lot louder like in this video so there is definitely a difference. I bought the Zapmaster from Walmart yesterday and even after making the mod it's a wimp compared to this HF model

LOL it definitely made a difference in your mind.That resistor just discharges the cap when power is removed.If you want to up the voltage just add more windings to the secondary of the transformer or add a voltage multiplier consisting of capacitors and diodes.

If it was in parallel with the capacitor then yes, it's a bleeder resistor, a safety feature to prevent shock as you say. The improvement seen here is because removing the bleeder stops charge permanently leaking away, at the expense of safety! A better method would be to change the switching so that when off, a bleeder resistor is across the capacitor. When on, the bleeder is switched out and the full charge is available.

Just did this mod and it does work. This zapper has a tendency to only stun flies, with this mod it makes a lot louder zapping sound and it definitely kills them.

Nice little mod there. I will put in my zapper an 3.7V Li-Ion battery which should increase the power a bit.

What also works well is if you get a microwave capacitor granted it abit big but if you wire that to the wires going to the racket you will get a bigger charge.. :D

My racket stays charged for a few seconds after you release the button. I once made the mistake of setting it down by the business end and I accidentally squeezed the mesh together. A quick tap is nothing, but touch those mesh for any length of time and you get a pretty good jolt.

well it does allow a bigger charge, take out the old one and solder one with more farad and higher voltage, and then maybe also use another kinda battery like 9v, but be sure your transistor and transformer can handle higher voltage/current, because else your transistor gets really hot

You shouldn't remove that resistor, it's a bleeder resistor (empties the capacitor when not in use). Instead what you could do is replace that resistor with a bigger resistor, and thus the capacitor will dissipate it's energy slower.

Upon test with a meter it does increase the output voltage and there is no increase in amps/watts which are the danger in electricity.

This video is old I know but a few things to point out that may have been mentioned before. 1. the zapper is only 600V because the main charge capacitor is just over 600V 2. that is the bleeder resistor it stops to from accidentally electrocuting yourself a month from now from it still being charged. 3. to actually increase the voltage you can input a higher voltage then the two batteries but it may very well burn out the capacitor and other electronic parts 4. the best way to increase the power is add more capacitors in parallel of at least 600v if less then they will short out and not work.

Capacitor in parallel would just increase their current lasting capacity... I would say higher voltage caps would be nice because higher voltage higher current ;D Despite lasting less the zap would be stronger with higher current ;D Only works if we raise the input voltage, the batteries. Otherwise, caps in parallel are fine but make the charging time longer when you press the button

Electrohacker45 was right, this is called a bleeder resistor and only purpose is to bleed the capacitor charge off when not in use.

I've also heard you can wire a 9v for the power instead of the 3v it's running on now. Ups the power even more.

Im sorry bur your mistaken sir. THe reason that resistor is there is so as soon as you let go off the power/ zap switch the capaciator gets discharged. When you cut it, after you let go of the switch, the capaciator will stay charged and if you happen to touch the wires, you will get zapped. Has nothing really to do with increasing the power.

Its not quite that simple. Rather, in the name of cheapness, the bleed resistor is constantly inline and pulling down the voltage of the boost circuit. the circuit will never reach its maximum voltage. I performed this mod on a basic single thickness racket (probably the most dangerous), and the higher voltage works better on small insects (such as gnats) that normally escape through the mesh.
