I have this 10ft EZ-EL Wire with the 3V Inverter that has three modes. it has an always on, and two flash modes. I wanted more control with a simple push and release button to turn it on and off. So for no real reason, just for something to do I decided to hack the inverter and I ended up sticking it on my bike to play with it. It is a crude hack, and can be improved on.

Step 1: Removing the inverter case

I started by removing the case. There are two screws - be careful not to loose the button.

Step 2: Inspection Time

On closer inspection and a few tests, we decided the new switch should need to interrupt the main power at the battery. If we selected a flash mode and disconnected the wire, then reconnected it, the inverter would reset itself and go back to an off state.

Step 3: Desolder Battery Clip

Desolder the positive battery terminal from the circuit board and bend the tab so it will no longer come in contact with the board when you reinstall it back into the battery compartment. Then solder a 6 inch or longer piece of wire on the back of the battery tab.

Step 4: Power bypass

Solder a 6 inch or longer piece of wire to the spot where you desoldered the battery tab.

Step 5: Bridge solder points

Bridge the two solder points to allow the inverter to remain in the on mode without resetting when the power is disrupted. When the power is returned, it will go back to a solid mode.

Step 6: Melt or cut a hole

Melt or cut a small hole in the side of the case to allow the two wires to come out from the side of the case once it is reassembled.

Step 7: Reassemble

Reinstall the circuit board and battery tab making sure the battery tab does not touch the circuit board. Assemble the case allowing the two wires to come out of the side of the case.
