OK, I ordered the replacement LED's. In the meantime, I connected A3 to A8, as a temporary connection.
Everything looks good... except: The four places I should be getting 0V, I'm getting 0.002V, on terminals 3,6,8,10 (when setting my meter to VDC "2"; It reads 0.02V when setting the meter to "20" and 0.2V when setting to "200")
Resistance checks are normal.
