    i tested stator do the numbers have to be right on or can they be off by a little bit

    Ohm-meter measurements, meter accuracy, coil specs

    Depends on which measurement

    For ohm readings on coils that are well over 10 ohms, I would expect your readings to be well within 10% of the spec.

    For coils with ohm specs below a few ohms, the meter accuracy can be misleading. A coil spec'ed at 0.35 ohms can measure 0.9, and still be correct

    Short your ohm-meter probes together, and note the ohms reading. Do this a few times to verify the reading is consistent. This is your ohm-meter's offset - the amount the reading is different from the actual ohms. Write it down.

    If your meter reads 0.5 ohms with the probes shorted, and 0.9 ohms when measuring the coil, the actual ohms is 0.9 minus the 0.5 offset;
    0.9 - 0.5 = 0.4 ohms

    Most multi-meter displays are only accurate to 1 or 2 'counts' on the last digit of the display. So that 0.9 reading could be off by 1 or 2, and the actual ohms anywhere from 0.2 to 0.6 ohms.

    Which means the measured coil in this example is somewhere between 0.2 and 0.6 ohms.

    For coils where you have several to compare (ignition primary coils, for example), consistency of the meter reading from coil to coil is more important than the actual low ohm number.

    like the exciter coil is at 448 should be 490 the pulser coil is at 87 should be 90 trigger coil at 212 should be 220 all oms are the numbers to far off and the coils are at 5.8 oms

    Those numbers are good enough.

    Check battery volts while cranking. Let us know what you find when ya do.

    batt volts go down to 11.4 when trying to start and 12.8 when not trying to start still no spark

    i did find a blown fuse the agc 1/4 amp but replaced still no fire

    Ok, check volts on the cdis red/purple and black when cranking.
