Need help on 94 ranger either short or bad alternator or something else

[Mechrick]

Truck is bank-fired, if you didn't unplug them you were ohming out two at once. 7.4 x 2 = 14.8 which is in the ballpark, so I'm betting they are ok, but let me know. Injectors should be white or light gray in color.

Injectors are denso f03e-a2b and look like they used to be white
