a few weeks ago, i posted a prolblem concerning the fact that the instrument cluster on my 03 escape, goes bezerk, with the indicator dials shooting far right, then dropping to zero, then finally leveling off to correct positions. well 4 hundred bucks later (ford diagnostic charges) it turns out to be a bad diode in the alternator, which spikes the voltage, thus causing the prolblem. ford wants 1000 to change the alternator. now i have seen alternators for this car as low as two hundred bucks! is there any special difference in the one that ford uses, or are they just ripping me off? help pleaseeeeeeeeeeeeeeee! outside of ford, how much should an alternator, AND labor cost for replacement? and is there any significant difference in the quality, or is ford just charging based on its name?
