Voltage reducer circuit
I finally figured out why it wasn't working properly, I had the two relays with 12V coils wired in series instead of parallel. That's why they'd work as first until they got a little warm from running and then would stop. IR and MacGyver, "Can't see any reason to have two relays; you only...- Mechanical_Matt

Voltage reducer circuit
Hi, Thank you for the quick reply. I wired the CL520 like the datasheet suggested, please see attached where the LED was to be ground referenced. I also uploaded a photo of the diagram in hopes that it might be clearer. In the hand schematic, "hobb" is the signal from the pressure switch...- Mechanical_Matt

Voltage reducer circuit
Hello all, This is my first post here after lurking a bit. I have been tasked with designing a circuit to drop the DC voltage of a vehicle to the fuel pump to ~9V so that the pump power drops therefore putting less heat into the fuel during idle. I've been at it for a while and feel like I'm...- Mechanical_Matt
