I have a 1988 Harley Davidson Sportster 1200 and I'm not getting a spark from the coil I'm getting power could it be the stator cuz I just got the bike and it looks like to me there's no electronic ignition like it was bypassed what would I do if it's bypass like that @
Hi, Justin and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at the ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

If you have power going to the coil but no spark, you've got something wrong with the "triggering" circuit of you ignition system.
One other thing, if your engine is the TC88 engine, (first year of production for some models) it probably has a "compression sensor" on it. If you have no compression, you will not have any spark. If you have your plugs out of the engine, you have no compression. So, screw a set of plugs into the engine, leave another set in the wires and grounded against the engine to test the spark.
The "triggering system" uses the signal from the ignition timing sensor that is located in the "nose cone" of the engine. Check this wiring from the ignition unit's "Black box" to the sensor. I seem to remember a plug that plugs in for this unit.
I'm afraid that this is about the only help I can give you with a stock ignition unit as I usually work with either earlier igniton systems or aftermarket units. I have very little experience with "stock" Harley units.
