Members. I posted yesterday regarding my 65 Dart gas gauge showing 3/4 full and my temp gauge pegging all the way. Turns out that the OEM voltage limiter is the problem, and a Thank You to the members who helped me solve this. I have another question....On the back side of the instrument panel frame, there is a condenser. What is this for, and will it be needed as I am installing an IVR4 solid state instrument cluster voltage limiter purchased from Real Time Engineering. Is this condenser related to the radio? I did upgrade the radio through Tayman Electrical out of Florida. Thanks again for the help on my 65 Dart GT Charger Clone. Much appreciated. sgrip65
