i think this means that the rectifier and battery is good?
have cleaned all my connectors down that way an all. so why does it still turn over slower than a slow thing. always starts but its a struggle

Could be a high resistance connection between the battery and the starter but if you are sure all the heavy guage wire connections are clean then it's probably a duff cell in the battery.

If you get a chance to check the battery voltage as you press the starter button, check to see if the battery voltage collapses as you try to start but bounces back up to 12v when you release the starter button.

If this is what happens it's classic failed cell symptoms and it's time for a new battery.

If the battery voltage only dips a volt or so when you press the starter button but the starter motor still turns over slowly then the problem is between the battery and the starter motor.
