A few days ago when I used my turn signal it worked a few time and then failed, at the same time I lost my fuel and temperature gages and the alternator light came on. I thought it would be a simple fuse replacement job.
Next morning, EVERYTHING WORKED! I drove it, used the turn signal... same scenario.
Drove home w/o turn signals. Inspected all fuses, rotated the same, no problem. No turn signal or gages.
Following morning everything is fine, didn't drive it for a couple of days. Now IT WON'T START, no gas gage, temperature gage or alternator light, radio works.
Where do I start troubleshooting it?
Regards

Don't know why it won't start with a charged battery, but it seems like your charging system wasn't working.
If the battery was dying then it would have been flat the next morning, but given a bit of rest it came back a bit. But not enough to run electrics after starting.
Anyhow, with a fully charged battery the idiot lights should be on in position II, engine not running. (And off engine running.) If not, check for proper connections of the thin red wire and short stiff blue ground wire at the alt.

I'm not familiar with brick electrics as I have never had any failures.
This advice applies to any car:
You should check the main hot lead coming off your positive terminal of the battery. It may come from the battery cable or from the connection at the starter. It will likely have a large fuse or a fusible link in it.
The alternator light symptom puzzles me. On a 20 year old Bosch alternator, you can expect failurs in the power and field wires, and with the ground to the alternator, but those wouldn't cause sudden failures of the turnlights.
Anyway
The next thing to check is in the fuse box with a test light or volt meter. Every fuse that is hot at one end, should be hot at both ends. Make sure that every fuse that you would expect to be hot with the key in the On and the Run positions are hot when the key is in those positions.

Sounds like a dying battery. And a bummed out altenator. Check your belts to make sure they are not loose, jump start your car and check the altenator output.

Thank you for your responses. That was my first thought. I charged the battery overnight. Starter cranks with plenty of power, however the engine will not start.
This weekend I will do a more thorough diagnosis on the fuses. I am aware that one fuse #15? controls the instrument cluster and the turn signal. If this fuse failed in addition to the fuel pump fuse I would end up with the proverbial "brick". But a dual failure????
Thank you

I think Fuse #13 is making intermittent contact, and/or maybe its wire connections as well.
As I read the Bentley diagram, on your '84 Fuse #13 feeds these 3 items:
1) The instrument cluster (power for key on lights & instruments)
2) The signal light flasher and switch
3) The Fuel Relay coil (relay powers the fuel pumps, etc.)
But I'm not sure about this, from your original post: "Drove home w/o turn signals. Inspected all fuses, rotated the same, no problem. No turn signal or gages."
Seems like the only way you could drive (Fuel Relay OK), yet lose the other 2 functions, would be with poor contact in the actual wire connectors leaving Fusr #13 (fuse OK, but no power getting to items 1&2 above).
I would use needle-nosed pliers to take all wires at fuse #13 off and on a few times to clean the connections. I think there are 2 connectors, 1 with 2 wires, all Blue/Red. No power there with Key OFF, but fuses 6 thru 10 are always HOT.
Then with fingers, carefully bend the fuse contacts a little closer for more tension on the fuse.
Let us know how it goes.

Thank you Lucid. I will verify and inspect the connectors and fuses this weekend. I am in So. Ca, for the past couple of weeks we have been drenched, a corroded contact sounds like the most likely root cause.
"Drove home w/o turn signals. Inspected all fuses, rotated the same, no problem. No turn signal or gages."
Sorry, what I meant to say was that I removed, inspected and reinstalled the fuses in question. Fuses were ok, however I remained with no turn indicators or gages.

That's what led me to thing about the wire terminals themselves. Normally there are just 2 fuse outlet terminals. So my guess is that the signals and instrument cluster wires share a common terminal, leaving the other one for the Fuel Relay (which allowed you to keep driving).
Good Luck,

Well Sir you are correct. This afternoon (lull in the rain) I "wiggled" the connection to the fuses and the car started right up, turn signal and instrumen cluster are functional. Since the vehicle is running I can drive it into the garage and do a more thorough cleaning.
Thank you
