TR2/3/3A The latest "It's always something."

The red ignition light is blinking along with the turn signal light? Electronics is not my strong point and I know some of you are very knowledgeable in that field. What would be the most logical cause of this and the best way to resolve it?

Light from the turn indicator normally appears to bleed into the charge light OR your charging system output is so low that he blinker bulb load is overtaxing it.

If this only happens at idle, then, yes, your blinker bulb is demanding more amps than your generator is putting out at idle. Generators have notoriously low output at idle. I would start by checking all your connections for your blinkers - especially the ground contacts.

It appears that the green, light green and green/brown wires have fused together. Not sure how far back the damage goes? I think there may be a short in the wiring at the direction indicator switch but I'll have to pull the horn assembly to have a look. (the horn assembly and indicator have moved out of position so I believe that is where the issues started). Turn signal wiring at the fender connections appear to be intact and not damaged. Not sure why the under dash fuse did not blow? What is the correct size fuse that goes there.
I pulled the glove box to have a look at the connections for the red ignition light and the green turn signal light and they appear good. When I turn the ignition key on the red ignition light blinks like a turn signal accompanied by an ominous hum until I shut it down?.... and the dash signal light will maybe blink once. Not good. Where to begin??

New update. I was completely wrong about the turn signal wiring. It appears to be intact and the turn signals work when I disconnect the Yellow wire from the ignition light. The yellow wire goes to the Alternator. Forgot to mention I had installed an alternator years ago. With an alternator the yellow wire from the ignition light does not go to the control box but goes to the alternator. I have a voltmeter gauge in the dash. Can I start the car with the yellow wire disconnected from the ignition light to see by the voltmeter gauge if the alternator is still charging?

The yellow wire should just be a signal wire...which would not make a difference if it is connected or not. The voltmeter should tell you if you are getting a charge, though, with the wire connected or not.

Wait on starting. What's this you say about fused wires? This absolutely has to be addressed as it is a symptom of shorting. A short is a direct connection, with no device (resistance) in the circuit, of a power wire to ground. I recall an earlier thread in which you referred to an open circuit as a short circuit. It is the opposite of a short. Do you have a short that caused the melted wires?

Turns out the wires were not fused. One wire to the flasher had scraped against metal in the hole at the firewall because the rubber gromet had got pushed in. Fixed that.

I can't start up the car till tomorrow. I taped up the end of the yellow wire at the ignition light. If the voltmeter gauge shows proper charging I can assume the problem is just with power going to the yellow wire. Not sure what would cause that? I would still be able to run the car normally with the red ignition light off I suspect. Would there be an alternative way to get power to the ignition light on start up?
Car started next day and alternator is charging as per voltmeter gauge.
