Lens Board Single Polarity modification<\/strong><\/p>\n\n\n\n<p>The dual polarity lens board high voltage switching relays can breakdown at voltages above 1kV and cause a variety of intermittent problems.&nbsp;&nbsp; Since most systems do not use the negative polarity, removing the high voltage switching relays and converting the lens board to a the single (positive) polarity can solve the breakdown problem and make the board more reliable.<\/p>\n\n\n\n<p>Modification Procedure:<\/p>\n\n\n\n<ol type=\"1\">\n<li>Remove the red cover (3 screws) that shields the high voltage components.<\/li>\n\n\n\n<li>Unsolder and remove the two Kilovac high voltage relays (K1, K2)<\/li>\n\n\n\n<li>Jumper the relays as shown in the pictures below.<\/li>\n<\/ol>\n\n\n\n<figure
