My Burnham RV3 blower won't start- blower relay is good. Starts if relay terminals are shorted!

Like the title says-. RV3 with power vent, propane, about 14 YO. I've ordered a new Aquastat, but have suspicions it won't fix the issue. Reads 120v at incoming side of new relay. Circulators run, mixing valve turns on startup, zone valves open/close. Schematic is a bit cryptic but I've done lots of testing and "wiggling" connectors while powered up with no response per se. One thing I read here is about the low water shutoff- will that prevent blower from starting up? I'm going through the Burnham diagnostic "tree" tonight but would appreciate any insights available.

Thanks!

    Do you have a digital multi meter?

    You can choose to do what you want, but you cannot choose the consequences.
