I have a 1998 dodge neon. A few weeks ago the speedometer started intermittently working. I just figured it was a speed sensor or even the cluster, it didn't bother me much. Today, on my way to work all the gauges were sporadic and intermittently working and the battery light was on. On my lunch break the battery light came on, gauges were sporadic, radio was going on and off, dinger was coming on and off, and the headlights were flickering when i was sitting still. I ran it down to the parts store to have the alternator checked, the gut told me that it the voltage regulator was causing the alternator to over charge, so he sold me a new one. When i got home, the new alternator says it is externally regulated by the car's computer. My problem is. i don't want to put a one hundred dollar alternator on the car and ir not fix it. Nor do i want to put a 250 dollar computer on it, and it not fix the problem. Can anyone offer advice or help me with this problem? Anything would be greatly appreciated , Thank you.

On my way home from the parts store the car was back to everything working but the speedometer. It was still acting sporadic.
