My 76 TR6 has ac and the volt meter always dipped down when the air and
lights were run together. I had never run both for more than an hour.
On the way home from TRF summer party I ran them both for over two hours when
smoke came out of the steering column.
The light switch on the column burned out fusing it in the low position but
only operable when pulled back in high beam.
I replaced the switch and now the lights work.
I pulled the radiator shield off and noticed that the blue and red wire
burned its way out of the wire harness (controls dip beam lights) I cut it out
and replaced the wire.
Question, if anyone knows:
Is it normal for the extra load of ac, condenser fan , and head lights to drop
volts to 13 or less. Or is that the cause of the melt down.
The car has the standard alternator. As far as I know when the dealers added
ac they did not change the alternator. The Fan and ac power leads are
connected to the bottom fuse; on opposite sides. The fan was grounded to
the front ground tab. The headlights alone do not cause volt drop, ac alone
w/fan will run at 13 1/2 to 3/4.
I know the alternator could be upgraded, but is there something else I should
look at for the cause of the melt down?
This is not covered in Dans book.
Thanks in advanced
