Checking Ignition Coil Windings Resistance - Husqvarna 2011 TE 630 Workshop Manual

ELECTRICAL SYSTEM

Checking ignition coil windings resistance

Remove the fuel tank (as described in Section "D") to gain access to the coil
(1).
Disconnect the coil connector (2) from the wiring, remove retaining screws (3)
and coil (1) and measure resistance in the primary and secondary windings
with a meter.
A: primary winding resistance: 4.5 Ohm (+/- 15%) at 20 °C.
B: secondary winding resistance: 19.5 KOhm (+/- 20%) at 20°C (without spark
plug cap cable).
If resistance is outside the specified limits, replace the coil. Also check the resi-
stance of the terminal cap contacting the spark plug.
