620 stating problem

[POP]

I took the starter apart, cleaned the motor and replaced the brushes. Reinstalled starter motor, starter which works fine but I went to star her up gas engine fires 2 or 3 time then quits!!!!! Me thinks it is running on the 12 volt system but fails to switch to the 6 volt system? I think I must have buggered up the 620 starter switch located on top of starter motor most likely the copper contact on the inside which is connected to the small wire that runs to the resistance module in the ceramic fixture under the dash . I need to know what small copper strip makes contract with in side the switch. Or have I screwed up some thing else up?

Just use a voltmeter or test light to that post and see if it has power when the starter pedal is pressed. If it has 12 volts then you must have a problem farther down the line.

check the resistor with the switch on to see if you got voltage to th distributer if you dont have power there, check your switch.
If it fires while your cranking then quits when you let up from the start pedal you dont have power to resistor from switch or the resistor is bad.
didyou hook 2 leads up at the starter one to the battery cable and one to the small terminal. the one to battery cable provides power to switch
