14.3 volts is good to go. Now just find that drop.
Remember several small voltage drops within a circuit are additive, or in other words several small resistances in series add to one larger resistance. Say .3 v at ignition switch, .3 v at bulkhead connector x2 because current passes through it twice once in and once out adds to .9 volts a little more drop at any of the other connections, and youre qiuckly at 1.5 volts or more
and so it goes.
