Pump Relay Wiring Diagram For Power - A Fuel pump relay is a setup used in automobiles to maintain a consistent voltage supply to the engine. This consistency ensures a steady flow of fuel to the engine. An automobile can have a long life if the engine receives consistent flow of fuel and air, especially during high speed driving.. To minimize voltage drop to the fuel pump. (Small gauge wire, switches and/or long runs to the pump may cause a drop in the power needed to run at full output). Use a Bosch relay 0-332-204-150, or a standard 12V/30 amp. automotive style single pole, double throw with. Step 5 – Testing the Fuel Pump Relay. You want to use either a 12V battery or power supply to test the relay. Connect your ground connection on the power supply to the ground pin on the relay.

It's for a pool pump, so once a day it'll be switched on, run for 8 hours, and turn off. I could just use a timer, but I want to learn relays and micro controller programming. Since they take so much coil current, could I use the relay I have to switch on the 12V needed to power the bigger relay? Would a SSR need as much power to switch?.
