Thank you but the electrical problem ended up being a ground wire that was broken up inside the dash. Oh well, the reman Alt. generates higher amperage and more voltage than the old tired stock unit anyway. Thanks for the reply! Ahhh, now I understand. I can really use the pics, because there isn't a hose off anywhere. Thank you!

Well fellas, no matter how I look at it I cannot find anything the "looks" broken. There isn't a disrupted piece of metal or plastic anywhere. I have included more photos to help you see what I'm looking at. Thank you for the help.

BIG THANKS to all of you. Really. This morning I dropped everything down so I could really have a good look under the dash and I came across a heavy ground wire coming out of the largest wiring bundle. It was hanging there with a broken ring terminal. A new terminal and a good ground location and everything seems fine. Thanks again to all of you for your help!!:) @Cougar - In looking at that solenoid we were discussing from the picture above, it doesn't appear broken anywhere nor do I have vacuum lines that don't have a home. Any other thoughts? Also, is it's function necessary? If it's for emissions will it effect the overall operation or mileage etc.? Thank you in advance.

@Crazyeights - there are two round relays next to the fusebox. I assume you mean these. I will check that out and replace with P&B relays. Great suggestion, thank you. @Ferox - It only has a pair of wires going into it. Here's a pic. THANK YOU BOTH!

Thank you to all. Great suggestions. I have cleaned the ground to the chassis and to the engine from the negative terminal of the battery. I have thoroughly cleaned both battery terminals and reapplied. I get 13.8 at the battery while operating, whether I have the fan and lights on or not. At the ignition switch the voltage is just over 14V. I'm not sure where else to clean or what to look for. Does anyone know what the small round "relay" looking and sounding device is that is behind (toward the rear of the car) the carb and a bit toward the passenger side? it has a small "post" that comes out horizontally with a black plastic "knob" that turns but doesn't seem to adjust or turn in or out. It was described in the original post. It clicks when the high beams are turned on but is a long way away from the lights and seems to be in too odd a location to be associated with the lights. Also, when unplugged, the lights function as normal. I don't want to go off topic since the rest of the problem is of higher priority, but since it now does the weird pulsing buzz thing it may be effected and/or related and might help in diagnosing. Many thanks for taking the time to read and respond.

The Alt I bought was a reman. The information said it was internally regulated. I called the company I bought it from to verify and they said it was definitely internally regulated. I checked voltage at the battery and with or without the fan and lights on it is right about 14.3. I looked for an external regulator and unless it is in the dash somewhere I am confident it isn't in the engine compartment. I have pictures ready, but I don't know how to upload. My apologies. Thank you again for your help!!

Thank you for the reply. I am under the impression that the regulator is internal in the alternator. I just replaced the alternator...??

I'm close to stumped on this and could really use some help. The symptoms: 1. analog gauges, at first, only read correctly at intermittent intervals and now not correct at all. They read and change but not correct. Oil pressure is the only one. Makes sense since it's mechanical. 2. When I turn on the heater/defrost fan, gauges get further off and fan doesn't run at full speed. 3. Turning on the lights makes the problem worse. 4. When I turn on the fan or lights all the dash indicator lights glow dimly 5. Now, as of yesterday, the dash lights pulsate, whether the car is running or not. 6. Fresh this morning, after the installation of the new alternator, I unplugged what appears to be a small computer box under the steering column and left it unplugged to see if it changed anything. It didn't. After coming back to the car 10-15 minutes later and plugging it back in a couple things happen. A. The red indicator light inside flashes 7 times slow and then 3 times quick. B. There is a small relay behind the Carb. that pulsates like it's trying to click into place but can't. I had previously heard it click when I would pull on the momentary high beam lever even though unplugging it didn't effect the beam operation. It pulses at the same rate as the dash lights. Really a buzz instead of a click. I installed a new battery and a new alternator to try to correct the problem. I'm at a loss... Your help and feedback is greatly appreciated.
