I checked the motor rating which as 12V 120A and bought a 12V 2000W 166A switching power supply thinking I can just use that instead of batteries. Fitted it and all that happens is the relays click but the motor doesn't run. All works on a 12V battery just fine. Am I doing something wrong or is it a faulty power supply?.
Here's what you need to know. There can be many problems that occur after replacing a car battery: The car may not start. This can happen for many reasons.

Shorting out: When your battery system can no longer supply at least 80 percent of its rated capacity, it is a strong indicator that the battery needs to be replaced. Typically, when it reaches this percentage, the aging process will accelerate very rapidly, leaving the battery vulnerable to immediate failure.
Unusual behavior: When batteries are approaching the end of their useful life, they often begin to display symptoms such as repeating alarms, flashing panel lights and abnormal terminal displays, indicating that replacement is warranted. Old age: Because manufacturers include a date stamp on batteries, you can always tell their exact age.
How much current is used to charge the battery depends on the battery charging circuit. The battery charging circuit decides how much current can be used. It might decide that for example 1.5 A is needed. When you use a 5 V 2A power adapter like is needed for your device, all will be fine.
First and most important, it is not safe to charge a battery with higher-than-specified current. Doing so risks damaging the battery (at best) and causing a fire or explosion (at worst). Fortunately, what you are asking about is not the charging current, but the current available from the power supply that supports the charger.
