I'd have to say that the starter amp draw seems normal enough. Sounds like it's not getting enough amps, when it doesn't start though. The solenoid has been changed, so there's really not much left. After you replace those cables, if the problem persists. You might want to take a look at that switch, and any relays that might be there.

Amp draw for starter motors. The solenoid will draw a few amps in the neighborhod of 5 amps. You can figure how much current it will draw by measuring resistance of the solenoid coil. Divide that resistance reading into 12. That will be the maximum possible amp draw of the coil if it's good. It has to draw enough amps to create a strong magnetic field to draw in the solenoid. Larger car engines will have solenoid current requirement 10+ amps up to 20 amps. But the motor itself will draw 100-200 amps under load when starting the engine depending upon the number of cylinders the starter has to pull through the compresson strokes. Most people don't have DC ammeters that can measure that high.
