I just bought a Ford Fusion Energi PHEV without an EVSE, so I bought a Nissan EVSE (Gen 3) on ebay, with the intent of modifying it to charge using 240V. Last week I picked up a Ford 120V EVSE, so it was time to modify the Nissan. I followed your instructions, using a 33k Ohm resistor and when I was finished I plugged it into my dryer outlet and... I got a flashing fault LED! Time to go back and verify all of the connections. Everything looked good, so I removed the resistor and plugged in the yellow wires from the old power cable. Plugged the cord into the dryer outlet and -- success! So what is going on here? I measured the impedance of the yellow wire circuit at 16k Ohms (in line with what some others have reported). Next, what if I double up my resistors to bring the impedance down to 16.5k Ohms? I gang a couple of resistors and put the multimeter on it and -- 1.6K Ohms. Whaat?? I check the resistor package - "3.3K Ohms." Nooooo!!! Off to Radio Shack to get the right resistors. I decided to pick up the 22k Ohm resistors in lieu of the 33k Ohm ones, as 22k Ohms was closer to the 16k Ohms that I measured from the yellow cable. This time after I put in the new resistor and plugged the modded EVSE into the 240V dryer outlet, I got a steady green "Ready" light and all was good! I've alredy used it twice to top off my car and it seems to be working perfectly, and twice as fast as before. Thank you for your original post!
