TM-20 Manual says to dismantle and ohm check resistors if 10-15V is not present at red (top) lead to GP relay. Most threads here suggest that 24V is proper until load is applied. I have 25V at the top and 12.5 at the pink/blk (with key on "run"), and my relay clunks when the blue is applied- but I don't get anything at orange (bottom) therefore my GP's don't get voltage. I only measure 3.2 ohms across pink/blk and light blue, instead of the 6-10 that the TM-20 suggests, but I don't know if this is due to a bad module (card) or if another wiring devil is at work. I bought a replacement relay but still no voltage out of the orange leads. What am I missing?
