9a217578, I have no power to display when I turn on key switch, no lights nothing visable on display at all, there is a faint alarm going continuosly. Checked fuses on D/panel, have b+ to board and across all fuses. The k1 power up relay pulls in but apart from that its at a stand still. Have double checked battery 37volts, plug and tips connections all secure and clean. Any help is good help, thanks in advance
