Electronic Boards
A blown fuse on an electronic control board
presents special challenges. Rather than just
replacing the fuse (and possibly watch it ‘blow’
again) the ZebraStat offers a diagnostic al-
ternative. The White wire (the HEAT1 circuit)
has a special function built into it. Between
the Red and White wires is a low-amp, auto-
reset, solid-state 'circuit breaker'. This circuit
breaker is set to ‘trip’ at 3 Amps,providing a
safe alternative to repeatedly replacing fuses
while looking for the cause.
Here’s how it works: Remove the blown fuse.
Attach the Red and the White leads of the
ZebraStat to the board or fuseholder where
the fuse was. No other leads should be at-
tached for this mode. Turn the mode switch
to ACTIVATE and turn ON the HEAT1 com-
ponent switch. All other component switches
should remain off. Now, the ZebraStat’s cir-
cuits are acting as a 'circuit breaker' with a rat-
ing of 3 Amps.
