Yep,if that fuse is good,go to the connector on the back of alternator and be sure it's seated. To test the warning light circuit,remove connector on alternator and all warning lights should go out,if so it's one of two things.
Either the alternator is not charging or the exciter wire from ignition switch is not energizing the voltage regulator to initiate charging. You have to determine which it is.
This is a good use for the multimeter I referenced in your no start thread.

Start by checking battery voltage with engine off,should be @12.6 volts. Is it? Start car and check voltage at battery now,if charging, voltage should be at least 13.5-14.2 volts.

If not alternator is not charging and is why all warning lights are on.
Remove connector from back of alternator, turn key on and with multimeter ground the black test lead to engine and probe back side of terminals in connector.
One terminal will have approximate battery voltage and this is the exciter wire from ignition switch to regulator in alternator. I think it's the white/black tracer wire. The other wire in the connector you already know is good because all the warning lights are illuminated.

When you turn the key on to the run position,all warning lights will illuminate and stay lit with the exception of seat belt warning light which is grounded through a timer and will turn off in 5 seconds. This is referred to as a bulb check.
All the warning lights receive voltage through the ignition switch and ground through alternator rotor. When engine is started and alternator begins to turn and generate voltage the rotor is energized and no longer grounded and warning lights go out.
Each different warning light is grounded through a switch or sensor dependent on circuit it's dedicated to.

So,if all warning lights are on, either the alternator is not turning(no belt) there is no regulator exciter voltage coming to alternator from ignition switch or alternator is defective.
Post back findings to help next person searching threads for answer to same symptoms.

A suggestion here,check simple,basic stuff before diving in to wiring.
Is the alternator charging the battery? If not work from the alternator backwards to wiring harness. Rule out simple stuff 1st before you start chasing your tail.
Remember KISS keep it simple,stupid.
Alternator needs a drive belt to turn it,has to be grounded,needs its output connected to main fuse link in car and needs an exciter voltage to the regulator in alternator to initiate charging.
