MS2 V3.0 PWM IAC Voltage trouble
Hi guys, I have a quick question, I have a MS2 V3.0, I've soldered in the TIP120 transistor and followed all the instructions. However when I measure the voltage on the Miata's IAC connector, it reads 12V with my fiddle port ON and 12.8V with my fiddle port OFF. My IAC is open all the time so I can't get it to idle below 2k RPM. What is the expected voltage on the IAC pins, 0-12V right? Also what voltage should I expect on the very pin FIDDLE on the MS2 DB37 connector? If i remember correctly mine was showing from 0V to 0.9V, is that good?
