I have a relay I'm using to power on various loads like a DC step down converter and and/or an inverter. The relay shows 1-6v across it when its closed with a load attached. It should be 28v,like it is when there is no load connected. I've tried switching the relay with a few power supplies and with my 28 battery. Both gave the same results. I'm at a loss for why I'm only getting the 6ish volts across the relay. I am using a SSR-40DA relay. Any help would be greatly appreciated!
