Trying to diagnose electrical problem and looking at schematic of ignition circuit. What does "to B+" mean?

Also, is the actual voltage that is sent to the coil coming from the circuit coming from the under hood fuse box #11 (10 amp) pink wire?

Thanks.

 

"to B+" means the wire comes from the battery, and the positive voltage at that point, measured to a suitable ground, should be very close to the BATTERY voltage. Generally means is is not a "switched" source of power, but can vary.

The voltage at the pink coil wire on terminal B of the coil should be about the same as the voltage shown on the dash gauge, which reflects the combination of battery voltage and the effects of the generator voltage. That wire is indicated as "to ignition" because the power from the battery has to pass through the ignition switch, which could be on or off.
