2002 Ranger, fuse 41 passes 12volts to the EVAP purge canister and transmission solenoids
The power for fuse 41 comes from EEC relay(PCM Relay) which is powered by a 30amp fuse(#7)
Battery"+"-------Fuse7(30amp)---------PCM Relay---------fuse41(20amp)-----------EVAP/Trans
Fuse 7 has power all the time
PCM relay closes when key is turned on, so fuse 41 has no power when key is off only when key is on.
This is a temporary fix to get you moving not meant to be used in place of Battery Light circuit.
You need to find out what happened to the green wire, and maybe run a new "green" wire back to the dash.
And check it at the 3 wire connector, the pin in the connector or the wire could be the problem.
After cutting the green wire check it's voltage again, could be you just need to replace the connector
When green wire is powered and engine running you should have above 14volts at the battery, but under 15v, after a few minutes that voltage should drop down to about 13.5volts.
Alternator's voltage regulator will generate above 14volts if battery is drained, like from using the starter motor.
But constant voltage above 14volts will damage the battery long term.
So voltage regulator will drop the voltage below 14volts after the "recharge"
