89 hatch with electrical problems: Loose ground wire?

[VietStaH]

yea either im not looking hard on the forums, or not reading through the haynes repair manual throughly.
reasong being is my cluster lights ( when i turn on my head lights ) dims on and off after a certain speed at round 40MPH and up, with also seatbelt light sometimes flicker, plus battery light flickers ( battery is good by the way ) i know i have a loose ground somewhere but i would really appreciate if someone like gave me a diagram of where all the ground wires are or a good pinpoint.

How do you know the alternator is fine?

You also may want to clean and tighten the battery terminals and the battery ground wire attached to the frame.
