Weird Electonic Happenings

[FONT=arial]I have a 2000 S10 withn a weird electrical problem. Driving ,usually at night and during acceleration, all the warning lights will come on and the speedometer will drop back towards zero momentarily. Nothing seems to be amiss otherwise. The engine continues to run and the charging system shows no deviations. Has anyone experienced anything like this?

Bad ground... Check your main grounds from body to frame and from battery to engine block... Pull, dip the end in a cup of baking soda water (watch it fizz!) then clean off with a wire brush, slather in dialectric grease... See if that helps you.
