Question about 2008 Sachs MadAss 125
Starter stopped working suddenly after cranking without starting for a long period of time just as the battery was getting low. The engine runs perfectly and kick starts with ease. The battery is new and holds a great charge, the starter switch is conductive and has been ohm tested. The starter has been removed and bench tested and turns immediately and with ease when 12v is applied. Where to look next?

Hi, Anonymous before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 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 type batteries fall into this scenario more so than lead-acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the 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.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter motor or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. Faulty ignition relay.
14. The electric starter is working but starter clutch has failed.
15. Check for engine trouble codes.

sounds like starter solenoid is staying energized sending continued power to starter. need to make sure you plugged the right wire from the starter button and not another hot wire w/ fulltime hot. also if thats ok need to test for power turning off to solenoid when releasing button. if thats ok try tapping on solenoid. lastly, make sure your positive cable from battery is hooked to starter solenoid, then another hot cable(longer) hooks from solenoid to starter, if you hook long hot cable directly from starter to battery, starter will continueous spin.

If you can hear the starter run, but no motor turning, the starter clutch is going bad. It is what allows the motor to turn over with the starter, and it idles while the bike is running.

SOURCE: Bike won't start
so where did you find the bad ground, and if I wire the negitive side directly to the frame can that be a permanant fix? Myne is doing the exact same thing

This happens when the engine trys to fire on the first "upstroke' of the pistons before those big flywheels get to spinning. This is common on stock ignition systems as far as I know. Harley may have changed the systems and I might not know about it but I doubt it. Some aftermarket systems, such as the Crane HI-4 have a spark delay system. The plugs will not fire until the engine has turned over three times. This gets those flywheels spinning and eliminates the start up kick back.
