Yeah it has a lot of electronics that cause a strain on the battery, etc.....but seriously, do you see this happening on a $50,000 Lexus? A BMW??
There has to be a fix somewhere.
From the above pdf file:
In closing, the computer monitors the ELD and the FR signal and gets a good idea of what the electrical demand is like. Using this information, the computer controls the charging system through the C circuit. It also uses this information to regulate idle speed. By turning off the alternator, the computer reduces the load on the engine, and thus saves fuel and increases power output when needed. In diagnosing some idle speed problems, these charging system inputs or outputs, being out of specification, can be the source of the problem and need to be checked for proper operation.
