4.a.3 - Drum Board Voltage Rail Check & Air Gap Adjustment
1.
Remove dyno panel to expose the drum board, which is mounted on the side of the
drum. On most models this is on the back left side of the dyno (while looking from
behind).
2.
Set multimeter to the highest precision DC voltage readout while still being able to read
5V (generally a 20V setting).
3.
Place black/common probe on the center terminal (labeled A in the picture above) of the
green 5 position terminal block located on the drum board.
4.
Place red probe on the terminal adjacent to the common terminal, labeled B in the
picture above. Reading should be between -4.95V to -5V.
5.
Place red probe on the other terminal adjacent to the common terminal, labeled C in the
picture above. Reading should be between 4.95V and 5V.
6.
If either of these readings falls out of the acceptable range check the distance of the air
gap between the transformer boards.
a.
Loosen the set screw on the collar holding the circular transformer board.
b.
Adjust the air gap spacing while checking the two readings to bring them into
range.
c.
Make sure the transformer boards are not so close that they may rub with
vibration or flexing.
d.
If adjusting the air gap space has no effect on the voltage readings and they are
still out of range, contact technical support at Dobeck Performance.
