I have a Club Car Golf Cart-Electric powered. I installed a Pioneer radio and many antennas. Can not get any good reception at all. Very Bad FM. I have grounded everything to the frame. Also tried grounding directly to one 12 volt battery. I installed the same set-up in a gas powered cart with no problems at all. What can I do to get good reception with the electric cart to fix the problem? Am I going to get an answer on my quertions???
