I have a couple of questions about installing instruments with a Rotax 912. I accidentally put 12 volts to my VDO CHT gauge and I think I fried it. The needle at rest is now at the max reading. I didn’t notice at first that the CHT gauge requires no power (except for the light) and the + terminal is for the sender. Does anyone know if applying 12 volts to this gauge will fry it? I called VDO tech support about 25 times and never got through. Also, I am not sure to hook up the VDO tach. The back of the tack has a ground, power tab and one sender tab. I hooked up the yellow and white wire from the 912 to the sender tab and the blue and white wire from the 912 to airframe ground, and have power wire and a ground wire going to the back of the tach. I then set the DIP switch to 1=on, 2=off, 3=off. Is this correct?
