Checking winding resistance
Primary circuit (A cylinders 2-3, B cylinders
1-4)
Bring the terminals of an ohmmeter into con­
tact with positive strip (central pin) and neg­
ative strip (pin 1 for circuit A and pin 2 for cir­
cuit B) respectively.
The primary circuit resistance reading on the
guage should be between 0.45 and 0.55 ohm
at 23 °C.
Secondary circuit (C cylinders 1 -4, D cylin­
ders 2-3)
Bring the terminals of an ohhmeter into con­
tact between the two high tension outlet ter-
Tne secondary circuit resistance reading on
the gauge should be between 12000 and
14600 ohm at 23 °C.
