What resistance did you add to the sensor? 47k ohm?The seller, Jason, has been a member of the GM-Volt forum for a very long time and came out with the original ERDTT defeat kit for the Gen 1 Volt for those who do not want to make their own. They appear well thought out and constructed, though I do not have one. I made my own with a sensor and resistor.
39k Ohm. 1/8 watt. $5/pack of 6 Amazon. Outside temp sees high 49°F. No ERDTT last winter or this winter which is exactly what I was going for. Mines not fancy, just an OEM sensor with the resistor wrapped around the two sensor prongs. It is a pain to install and remove which is why Jason's switch solution is nicer.What resistance did you add to the sensor? 47k ohm?
It doesnt "kick in", instead it continually gives a false, higher temperature reading. My dash temp display is always in the 40's while the modified sensor is in. I haven't seen any affect on defrosting, but I normally use manual defrost.What temperature is displayed on the dash when it kicks on? Does it have any effect on auto defrost or anything else besides ERDTT?
Mine has no switch, mines always on. Then again, I didn't spend $50-$75, I spent under $10. If you want a switchable mod, then get joesonvolt's very nice unit off ebay. His has the added advantage of install once and you are done. Mine is a seasonal install and removal.How easy of an install is this? You mentioned switch, I'm assuming it's on the unit your installing correct?
Awesome, thanks for the details, zanhecht. I may eventually make one of these, but with work and other projects, well, someday!My install cost me around $25 including a switch, but that includes $5 in shipping from Mouser and overly expensive waterproof switches I bought from Amazon (I likely could've purchased them from Mouser for a lot less).
