2000 Mercury Mountaineer V8 Four Wheel Drive Automatic 178000 miles
Hello out there! I am happy to see a forum I can send my problems too with good results. I hear you guys are the best. My question is about my 2000 Mountaineer with a 5.0 engine. I was driving home from work a week ago and suddenly my radio was like being turned on & off by itself. A few seconds later it went off completely. Next at every street light upon stopping at the red ones, I had very little response upon accelelrating. I had to feather the gas pedal in fear of losing power & the engine dieing out. I knew I was losing power to the spark control somewhere. It took me 35 minutes to get home signing of great relief. The trip to my work has its downs from very poor neighborhoods to pass through everyday. It seems when I was able to hook up a battery charger the meter would set at a 12 amp charge for a few minutes, & then completely shut down. I tried that 4 times getting the same results. I hear tell if charging a battery & if you can get the engine running you can hook up a volt meter to it. First in the DC mode and read if 13.5 volts are reading in the idle mode (800 RPMs) & then next switch it to the AC mode to see if a reading shows other than a blank. If a reading shows that will mean a diode is bad causing the backflow in the design of the system correct? Its seems to me bothe the battery & alternator could be bad. It had corrosion on the two battery lugs and the alternator looks very dirty and old, too
Thanks for any help out ther!
