New cluster did not fix the dead Gauge issues HELP

Keep in mind that I'm just guessing. Since this thread starts at round 2, I'm also guessing your round 1 was copper traces blistered off the circuit board. If that was your thread and condition found you can confirm it was the traces to the gauges.
Since I'm reading the ground is good and the limiter is working, I'm betting the gauges are dead. If I'm correct on a points I wouldn't have expected those gauges to work.
When the copper traces blister and lift from the board they can touch one another creating unimaginable short circuits. The result would be widespread damage.
As for the dash lights... the dimmer rheostat must be good and must be turned up. Most headlight switches are replaced because only that rheostat has failed.
Go to the fuse box with a simple test light. Find 1 fuse that doesn't get power at either end unless the headlight switch is pulled one click. With the switch pulled there should be power at both ends of that fuse.
