TIM-6
Basic Kit
 
For use with 6 volt batteries
(or 4.8 minimum to 7 volts maximum) on any engine type.
Kit contains: (1) TIP42C
Transistor, (1) 2N2907A Transistor, (4) Resistors, (1) LED Timing
Light, (1) 3 Amp. 40 volt reverse polarity protection diode, (1) Hall
Effect Magnetic Sensor, (1) Rare Earth Magnet, (1) Drilled
Printed Circuit Board, Complete assembly and installation
instructions..
The circuit board is
approximately 1.35" wide by 1.70" long. Just to the left of the circuit
board is the Hall Effect sensor and the dot just above it is the rare
earth magnet which is just 1/8" in diameter and 1/16" thick (3.2mm x
1.6mm).
Note: Due to component changes,
some PCB holes may need to be drilled slightly larger.
TIM-6 Deluxe Kit
Same as
above, except also includes a PCB Screw Type Terminal Strip
for ease of connecting or removing your battery, coil, and other wires.
Also available fully assembled and tested for $40.00.

Electronic
Buzz Coil
 
What's a
"buzz coil"? It's very similar to the TIM-6 ignition module
except that instead of generating one spark for each power stroke, the
buzz coil can generate dozens for each power stroke (200 per
second - duration depends on the "dwell angle"). This greatly
improves combustion for slower hit-and-miss or older engines that may
not have much compression. The new PCB is slightly larger
than Jerry's original and displays part outlines and labels for easier
assembly. Also included are wire terminal blocks to make wire
hookup much easier.
The "Buzz
Coil" is so named because old units (i.e. Ford's Model T) were
mechanical that also incorporated the coil, and they "buzzed" when they
were activated. Our "Buzz Coil" replaces the mechanical relay
of the old units. A separate coil is still required.
For use with 6 to 12 volt
batteries and coils.
Kit contains: (1) NTE2312
Transistor or equivalent, (1) NTE24 Transistor, (2) 2N2907A
Transistors, (12) Resistors, (1) LED Timing Light, (1) LM555CN Timer IC
or equivalent, (3) Capacitors, (1) Drilled Printed Circuit Board, (2)
Screw Terminal Blocks, Complete assembly and installation instructions.
The circuit board is
approximately 1-1/2" wide by 2-1/2" long. Since many builders
connect these to their "points" system, the kit does NOT include a Hall
sensor or magnet as these may not be needed. However, if you
are not using "points", be sure to order a Hall and magnet from the
"Ignition Systems" menu. Order an extra Hall sensor and
magnet if you wish to use the "spark saver" option.
For hit
& miss engines, order an extra Hall sensor and magnet if you
wish to use the "spark saver" option. This feature prevents
the ignition from firing while the engine is "coasting", greatly
increasing the life of your battery (details included in the
accompanying instructions).
Also available assembled and
tested for $55.00. Click on down-arrow in order box below.

sister site www.model-engine-ignition.com
for info on the new PICTIM
ignition module. It is our best and most advanced ignition module yet! Kits are just $40.

"My engine is
now running and wow what a difference, like a different engine, runs
smoothly and never miss fires as it did with the old system and stop,
really impressed with this Hall system and many thanks for all your
help and answering my questions and supplying the parts so I could fit
one."
