85 250sx not getting any spark at the plug. Downloaded the service manual and started doing ignition system checks.
Checked various continuity readings (ignition and run switch) between black/white and green wires at CDI plug, all checked good.
Measured resistance between (ignition coil) black/yellow and green wire at CDI plug, 0.4 ohms (standard ie 0.1-0.3). As suggested in manual, check resistance at coil terminals, measured 0.3 ohms (standard is 0.1-0.3)
Any ideas if it is normal to measure outside the acceptable range at the CDI plug , but measure inside the acceptable range when reading across the coil?
Since the value is at the upper range, should the coil be replaced?
Also checked measurements for alternator and pulse generator at CDI plug and measurements were all within range.
TIA for your input.
