My advice to you is the same as those with a regulator strapped to the bulkhead - bin it and use an adjustable bias valve. The simplest solution is to remove the factory proportioning valve and install an adjustable proportioning valve in its place. Once you get the plunger centered the brake warning light should go off and you can finish bleeding.
