Need Help, I think its the Alternator
Need Help, I think its the Alternator I just got my car back with the new block on Saturday, today with 600 miles on the new block i was at the taco bell drive through with a friend. We were waiting for our food when the guages started flipping out. The Tach and Speedo were going from 0 to 7000 RPM 155 MPH and all the service lights were coming on and off. The car idled fine and seemed ok. I couldnt check the voltage because it too was going crazy. It kept doing it, we got our food and i drove out into a parking lot where i killed the car. When i tried to restart it it wouldnt start. I jumped it off with a portable jumper box and it fired up but only pulled about 10 volts. We figured to try to make it home. I got about 5 miles down the road and the voltage had dropped to about 4 volts way in the red. It was still running well though even the guages were still funny and my trip odometer had reset itself. I finally hit a red light and when i slowed down enough in neutral she died. Now when i start her i have to keep the revs up around 2500 just to keep her alive. Finally i gave up and called AAA and towed her home for 45.00 bucks. Im about to go out and rip into it but wanted to see what you guys thought. I am running an ASP crank pulley and a Mezeire Water pump but for the last 600 miles shes been fine
