No worries, even if you reply you still can only see the original post for some reason.

When testing fuse 1, removed it fully, this is where the A1 contactor gets power before going to battery positive. Make sure to unplug the battery first. It is held in by a bolt/nut on each side. Take your meter and test on one end of the fuse and the other. When testing i also recommend to wiggle the fuse a bit to see if it is slowly dying. A good fuse will test at 0.1ohms but it's acceptable at 0.2 or 0.3 ohms.

If this fuse tests good. I would test the control wires for the A1 contactor. You should see battery voltage when activating travel. If you see the right voltage there I'd replace the whole contactor.
