Auto Scanner: Alternator could be at issue in odd lights problem - The Salem News
Q: I have a 2004 Mazda MPV. About six months ago when I started it up, all the gauges seemed to spring up fast and then settle down, and the traction control system light, traction control system off light, brake light and antilock braking system light all stayed on. When I... This kept happening, and when I brought it to a Mazda dealer, they could not tell me what was wrong. Do you think you know what the problem could be. A: Most times when I see this kind of problem it ends up being an open diode in the alternator. When the diode, which only allows electricity to flow one way, goes bad, the alternator will start to produce an alternating current. When this does happen, it makes very strange things happen in your car, and a telltale sign is exactly what you just talked about. I took it for an oil change and asked the mechanic when I could change the timing belt. I spoke with another mechanic who told me I didn’t need to change the timing belt unless the car was before 2002. I’m confused. Q: I was wondering if you could clarify an old wives’ tale for me. I was told that you should never pull into a gas station for fuel when you see the delivery truck dumping gas into the underground tanks. Also, how about gas in the underground tanks from a gas station that closes for two to three weeks while they go on vacation. Source: www.salemnews.com
