If your Chapin Paint Sprayer pump won't start, ensure the voltage is correct (12-13V) and that the electrical connections are properly made. Check the fuse or breaker, and verify the pressure switch operation. Also, inspect the rectifier or motor for open or grounded circuits and check for a locked drive assembly. Finally, confirm the correct voltage at the switch.
