Do you have a volt meter or a multimeter?

Do some voltage checks. While your accessories are running, measure battery voltage. Then, measure the voltage at your turn signal wires (when they are on).

Are you using 1157 bulbs in front and back? What fender lamp numbers are you using? The flasher unit depends on current to cycle but it also depends on 12 to 14 volts. When your car is charging (running) the battery should be at 14-volts. What is your battery voltage?

Fender lights should never stop the flasher from working. If anything they ADD current which makes the flasher cycle slightly faster. Each side should have a front, a rear, a fender and a dash indicator, all on and flashing at the same time. If all these conditions are true and the lights stay on, try a different flasher unit. - Dave

I don't mean to sound ignorant, but how do I check voltage at the turn signals, where do I touch the probes and what setting on the voltmeter do I use? This is all new to me.

All of the lights are flashing at the same time, I don't have a dash flasher light, 1966 didn't have them, I believe. The flasher unit is original, I should take that out and replace it. Do they make a modern version of the turn signal unit?

Mike: Make sure that your four way " emergency flasher switch on overhead console is not on . The two relays in the trunk , next to the sequential package are known to go bad due to moisture .
Also, there is a relay , for turn signal indicators , ( C5SB-13A366-C ) that is located just below the light switch under dash, just above your left knee .
Have found over the years that if there is a problem in the rear with your sequential lights , when operating, the signal indicator light on fender will stay on solid . ( one bulb could be out or relay problem in signal package ) .

ps. The ground wire for the signal indicators is shown on the schematics so new for '66 model year .

I heard you can open up the turn signal indicator unit under the dash and bend a prong to get a better connection, I should try that, I see where it is located, getting it out might be a challenge.
The sequential lights work good, no burnt out bulbs, I have a feeling it's the underdash unit, will see I guess.

If your indicator light works on one side and not the other side , keep in mind that the signal , after the relay goes through the signal switch on your steering column , so if one side works and the other side does not , most likely your signal relay is o/k . Problem could be in the signal switch .

Both fender indicators freeze up when alot accessories are turned on, the right one is worse, but they both do it, the light stays on and pulses. If I rev the motor they tend to start flashing, once I stop revving, they freeze again.

Everything goes through the sequential unit in the trunk. I would first check to make sure you have a solid ground going to it. Both the turn signal flasher/motor and the turn signal relay can be problematic after all these years. I've had turn signal relays with broken and loose solder joints that I've had to repair. I've had motors that stop working when the voltage drops slightly due to accessories being turned on. Most likely the new solid state flasher assembly will fix your problem but it's an expensive fix. Have you checked your alternator to make sure it's putting out sufficient voltage under load.

Alternator is new, last time I checked it was putting out sufficient voltage, everything in the rear of the car seems to be working properly. I will double check the ground in the rear by the sequential unit and the solder points, but I think I will probably have to bite the bullet and buy the new turn signal unit, $95.00 on eBay, anywhere I can get it cheaper?

Where did you see the unit for $95? The electronic replacements are around $230.
