My
`54 TF developed a condition that would result in a dead battery after
being parked for more than a month. Normal trouble-shooting tests
revealed a constant current drain of about .2 amps. The problem was
traced to the horns. It seems that rain water had entered them and
built up a conductive layer of corrosion near the "hot" wire
connections that caused a leak to ground. A good cleaning and drying
cured the problem. I decided to go a step further and prevent a return
of the condition. As wired originally, a hot wire carries current to
the horns and another wire runs to the horn button near the driver.
This button blows the horn by completing the circuit to ground. I
changed this, and now have one terminal of the horns grounded. The
other terminal of the horns is still connected to the wire that goes to
a "hot" terminal on the ignition switch. The result? Horn operation
normal and no possibility of future corrosion causing a dead battery.
