Well Ive been chasing an issue with my lights and dash lights, Last night I was probing with my multimeter and the ground has power?

I know this isnt right. But I'm not sure where its normally grounded to the wire leads into the main harness and I have to cut all the tape off.

Could I just make a new ground? like pull the plug and solder another wire to the connector and run it to a new ground?

or what would be the easiest method of finding the short?

 

More than likely you have some melted/shorted wires somewhere in the circuit. You could abandon your ground and make a new one like you suggested, but that won't change the fact that you have a short somewhere. It could get worse and cause a fire. You need to find the hot wire that is shorted, locate the short and fix it. Start by checking all of your lighting sockets and wiring in close proximity to the sockets. Check your bulkhead connector at the firewall - I have seen these melt and short out before. There isn't really any easy way to go about troubleshooting a short circuit. Sometimes you get lucky and find the culprit quickly, sometimes you end up gutting the car before you find it. Good luck.

Edit: if any of your lights do still work, check to see if any of them are dimmer than the rest. If you find one that is dim, more than likely the hot wire that is feeding that light is the wire that is shorted.
