I have a84 Dodge Ram 150 with a 318 engine in it. The trouble is the charging system. It's got a 78 Amp alternator that's putting out 13.5 Volts at the alternator post before it even gets to the voltage regulator. I get the same reading at the battery after the voltage regulator. The alternator guage shows a slight discharge at all times and even moreso when the lights are turned on. In a matter of a week, the battery will run down and eventually leave me on the road with no power.
The battery was replaced with a brand new one not a month ago along with two new voltage regulators (thinking it might be a faulty one) but to no avail.
If the alternator is putting out 13.5 volts at the terminal and the same at the battery, why would the alternator guage show a slight discharge. If the battery runs low, wouldn't the guage show that it's charging instead? And why does the battery (a new one) go dead over a period of a week? I'm confused unless there's a short somewhere in the wiring but if that were the case, then I'd see a spark, even a small spark if something was draining it, correct?
I'd sure appreciate some expert advice on this one because I'm at my wits end. LL
have the same problem?
