I'll try this.
Yes, the ground was reconnected. I repeated the process three times just to be sure. Yes, I was using an inline fuse.
Check to see that there is 12V at the switch with the test wire connected. I suspect you did not reattach the battery ground because all you did was replace a hot wire with another hot wire.....thru a different fuse (in an inline fuse holder)....right?
If you do have 12V at the switch, the next step is to take off that test wire from the B and touch it to the L momentarily. Do not remove the yellow from L when you try this. This will be bypassing the switch, to be sure the switch is not bad.
