Recently my headlights have been flickering from high beam to low beam in rapid succession, but only periodically. Also sometimes when I try to turn on brights they won't come on, and then suddenly they may come on and then flick back off, or may stay on. Autronic Eye is turned off but need some thoughts on what may be causing this. Bad floor switch? Short in system? Doesnt seem to act up until I try to turn on brights, then it is anyone guess what will happen.

Doug, you just have to reroute the wires. They are routed a different way, than a car without the guide-matic system. They normally come straight down the fire wall to the dimmer switch.
Thanks, Russ. The disconnected 3 pront connector will not reach the dimmer switch so I assume that I need to splice longer wires into this connection, or am I missing something?
Thanks,
Doug
At the guide matic relay, disconnect the 3 prong connector, and run it to the dimmer switch. That takes the guide matic system off line.
Might as well disconnect the power to the guide matic too.
Well I cleaned the grounds (which they needed) and that did not solve the problem. I then replaced the dimmer switch, and that did not solve the problem. Read through the shop manual troubleshooting suggestions and got completely confused so decided to tackle it on another day when I have more time. I will try Russ' suggestion of bypassing the guidematic next to see if the problem lies with that system but I am confused as to what I am suppose to disconnect and re-connect at the relay. Do I disconnect the three prong female connector at the dimmer switch and hook another three way female connector to it instead (that normally runs to the relay?) I know I will eventually get this solved (and it is fun trying to solve the mystery), but you all offer the best clues (suggestions) Thanks. .
Thanks guys for the suggestions. I will check the grounds and go from there. I learned a longtime ago to walk away from a project if I start to get frustrated as like you said a solution will eventually come. I also know that members on this website have always provided good information on where the issue may be. Thanks again and I will report back with what I find.
The grounds are always suspect, but I would look at the dimmer switch shorting out at the plug. You can disconnect the guide-matic system, if you think it is malfunctioning.
The normal headlight wire harness runs to the guide-matic relay box. Its on the interior firewall., just left of the steering column. There are 2 connectors. Unhook the connector that will run to the dimmer switch. Plug it in the dimmer switch, and disconnect the power to the guide-matic.
You can leave the single connector attached to the dimmer switch, as it's just a ground contact.
Start with the grounds, as they probably need to be cleaned up anyways. Then go to the dimmer switch.
Doug, Tony is spot on with regard to the grounds. Follow the forward lamp harness just through the radiator support grommet and you will see a black wire that attaches to the frame via 5/16" hex screw. If that ground starts to lose contact, the lights will start to flicker. Also check all other grounds. Here is are pictures of the left and right side forward lamp harness grounds:

I found a diagram that illustrates the main factor in determining a spark plug heat range that I was trying to describe to you during the chapter get together.
Here it is:
The main factor is the length of the ceramic insulator from the middle of the spark plug to the tip (where the spark happens)
The insulator…

Good Morning all!
I took the 64 into the shop to have some adjustments completed and in the process decided to have the lower ball joints replaced as was recommended the last time I had it in. I ordered the parts and came into the shop. They quoted me nearly $500 to replace those lower ball joints requiring nearly 4hrs of labor. Now this is a reputable shop and they know me by name here and they will continue to get my business. I am just questioning what on earth is…
