alternator
 

I am still having a problem with my car. It will hesitate like you hit a brick wall every few times you rev it up:eek: ........My voltage gauge stays at about 14.2 untill you push the brake, or turn on the blower. . . I am thinking it is an electrical problem, but I don't know what to do. Today I put a new neg batt cable on, so as to reground everything. but still hesitates

ALSO, when I am reving it at like 3k(in neutral), and then I put my foot on the brake, the voltage drops a little, then if I let off the gas the voltage drops again(to below 14, like 13.9) when it gets to 1k rpm(or lower).

This is so frustrating, and crazy. I am about to take it to mazda next week. PLEASE let me know if you have any ideas.

Voltage drop is normal. When i'm running the heater and hit the brakes mine drops below 12v... either get a bigger alternator or upgrade to LED's everywhere in the car.
