Electrical Issue

I have a '99 Cougar with a 2.5L V6. Recently the lights starting flickering. Strange as that is, it seems to only happen when the engine is around 1250 RPM. They seem to pulsate at a constant rate also. I've had the battery and alternator checked at Advancd Auto. Any ideas?

They seem to pulsate at a constant rate also. I've had the battery and alternator checked at Advancd Auto. Any ideas?I'm having the same problem right now. I was told that it could be my alternator, battery, and the connection. I replaced the alternator, battery, and new terminals. None of this worked.

This has been discussed before, and luckily I found my original post on it.

Heres a TSB I found regarding this:
"Should a customer express concern about flickering headlamps, wavering illumination of the instrument cluster, interior lighting and audio unit at low ambient temperatures when starting and at idle in the first few minutes after starting the engine, the probable cause is an extremely high resistance in the battery wiring harness from the central junction box (CJB) in the engine compartment to the B+ terminal on the generator. To rectify the concern, an additional generator/battery cable should be installed."

Btw, read this thread on contour.org on how to possibly fix the problem.

Anyone heard of Nology plug wire, electrical & accesories? I hear they're top of the line! I haven't purchased any of their merchandise, but intend on doing so with all their available products! Just wanted your opinions on what you think & if there's better?
