Narrative:
Aircraft X was IFR at 8;000 5NM west of talli intersection. Aircraft X advised that his acard went out and came back then went out again. Aircraft X said that he did not need to declare an emergency he just needed to descend to VFR conditions to see what the problem with his equipment was. I descended aircraft X to 7;000 and then gave him a turn to 320 and continued his descent to 6;000. Aircraft X had some VFR conditions in the area and wanted to continue descent to avoid the clouds. I gave aircraft X descent to 4;000 and advise me if he needed any other assistance to remain in the VMC conditions during his descent. He then asked to descend to 3;500 and the MVA in the area that was 3;700; I told him about the MVA and descended him to 3;700. I verified that the MVA was at 3;700 and gave aircraft X the altimeter due to his altitude showing him descending below 3;700 on the scope. Aircraft X responded that he was climbing back up to 3;700 and wanted vectors towards [a nearby] airport. I gave aircraft X a heading of 150 and maintain 3;700. Position relieve briefing was started at this time and I gave the next controller all the information about aircraft X and his intentions to remain in VMC conditions. Before the end of the position relief briefing I gave aircraft X a heading of 180 and maintain 3;700; vectoring him towards an area with an MVA of 3;400 if he needed to descend anymore. I stayed in the TRACON to see if the next controller needed any assistance with the position.no recommendations to prevent the re-occurrence of this event due to it being an equipment malfunction.
