Ok, '85 Mark is running good but a strange electrical thing is happening.

At night the headlights will brighten then in a bit dim. They don't go to high beam but there seems to be an electrical surge.

Then, after driving for a bit, if I hit the brakes my radio will shut off then turn back on. (no loss of stations and no other electrical items turn off) :frown:

This also happens when I dim the headlights from high beam to low beam, or when I switch on the turn signals.

Now once this happens and the radio comes back on it will not do this again for a few seconds. I can hit the brakes than the radio turns off comes back on I can immedately hit the brakes with nothing happening. Give it about a block and it will happen again.

Car needs to have been running for a bit before this starts to happen. (15 min or so).

:Bang
 
I might be inclined to do 2 things.

1) Change the headlight switch.

2) Test the alt and battery for proper voltage output.
 
Check battery, connections, major grounds etc. Maybe even the ignition switch.

Changed the Voltage reg this morning and the radio problem seems to be fixed.

I will have to wait until tonight to see if the light problem is fixed.

Thanks :Beer

Last night was the first night that I got to take her out and check out the lights.

Lights are working great - No more bright than dim. No more problems with the radio.

All is working fine.

Now all I need to to is find what is causing some of the dash lights not to light up. The fuse keep blowing must have a short somewhere. I heard that the pannel dimmer switch can sometimes cause problems.

I can't dim my dash lights so I am thinking of replacing the switch.
