Well, after 109,000 miles and 6.5 years; my alternator's dying. Had it tested at both Autozone & Advance Auto w/same conclusion: Bad diode in the alternator is draining the battery when the Trac's shut off. However, there are two different replacement part numbers (and $40 price difference) depending on build d date. And of course, mine calls for the more expensive one ($220 new). So what changed 1/2-way through the 2004 production year regarding alternators? Not happy about having to buy the more expensive one...
