I second checking the wires. Had a problem on a weekend road trip
where one of the smaller wires in the plug that goes into the
alternator broke. Not fun trying to pry out the connector from the
plug and uncrimp it with minimal tools. With the car at home, give
each wire a tug to make sure they are all secure.<br>
<br>
As to rebuilds, I don't have faith is most rebuilders. My rebuilt
TR6 starter lasted a full week before failing. I think they are
just out for a quick turn.<br>

Subject: [TR] Alternator not charging battery - 1976 TR6<br>

<div id="m_-1054301579653368455yiv9047746190">

<div> Here’s a synopsis
– Almost new battery went dead. Charged battery and
took car to shop. Meter shows alternator is not
charging battery (only 12 volts, not 14.6 as per Dan
Master’s book). Buy rebuilt alternator and the same
thing happens. Swap alternator for a second rebuilt
unit – same thing, battery is not being charged. Tried
3 different meters – all showed 12 volts. Hard to
believe I got 2 bad rebuilt alternators. What’s
wrong??</div>
