Now, here is a tough question to figure on this topic - so these old DSI boards are not available OEM anymore. Are there alternatives? I'm thinking the logic on these is super simple, could someone rig something to work? My furnace is from '78, it's a Coleman Presidential, and I have found that my issue is the DSI board is not sending voltage to my gas valve but is getting the signal that everything is good for firing (so blower turns on, flag switch=good, 12VDC to post #1, but 0 VDC at post #4). Now that I think of it, I have not tried jumping the gas valve to trick the board into thinking that gas is on to test the ignitor.
