It's hard to provide exact instructions when we don't know exactly how you have the SSR and bed wired. Does the + from the power supply go to the SSR first, or to the bed first?
the difference on the out is 0
The voltage difference on the input is 12v
One easy thing to try would be to temporarily jumper across the SSR output terminals or remove both output connections from the SSR and connect them together. Turn on the printer and see if the bed starts to warm up. If it does, and the SSR control input is known to be working, you pretty much know you have a bad SSR. If the bed still doesn't heat up, there's a problem in either the wiring or the bed itself.
