My Power supply is 12VDC and it runs 12VDC under load and no load, but I have relay that requires 12V to switch, but it runs trough protective 1N4001 diode and that drops the Voltage down to 11.3VDC and it won't switch the realy I can only hear clicking noise. so My question is if I switch to 9V relay can I still use 11VDC or will I burn the relay ? or is there a way to drop 2V some how ? I tried another diode or two but that does not really work. The load (pump) runs at 600mA.
