two soleniods controlled by one relay

[Alan Anderson]

Yes, you can.

Make sure you have a red wire connected to the control/power of the solenoid, and a black wire connected to the common/ground.

Power a Spike from a 20A circuit breaker on the Power Distribution board. Connect the first solenoid's red wire to M+ on the Spike. Connect the second solenoid's red wire to M-. Connect both black wires to the GND pin of the Spike (where they will find a path back to the PDB).

To turn both solenoids off, set the spike OFF.
To turn the first solenoid on, set the spike FWD.
To turn the second solenoid on, set the spike REV.
To turn both solenoids on, set the spike ON.
