There are far too many possibilities to list them all, but in general you need to isolate the individual components and test them, one at a time.
First start with the battery. test it, make sure it's fully charged. Make sure the battery terminals are connected and in good condition.Make sure the connectors to the ignition are all plugged in and functioning properly.
This is the part where you engage the "scientific method" that your high school teacher talked about:.
If it's bad, the pump motor will not start. It can be checked with a volt meter. You should have either 115 volts or 230 volts in and the same going to the motor.
12 volts
A motor will operate on 400 volts.
You should not go above 240 volts for that type of motor.
12 volts
what is the full load amps for 2.4 hp motor at 460 volts ?
Depends on the ratings(volts, amps, etc.) Definitely not an AC motor.
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
No, unless the motor was wound for dual voltage operation, which it will state on the motor nameplate, a 110 volt motor run on 240 volts will be damaged.
A circuit board is the inducer motor. It runs off of 120 volts.
There will be a significant reduction in the mechanical power output available from the motor.
A DC motor can be built to operate on any voltage.
