Cluster sweeping, and low light output

Well I had the same problem but discovered 2 things that could have caused it. My ground at the front right motor mount came undone when the bolt worked itself out. I had pulled the bolt and added a washer under the motor mount to help align clutches (it did work) but apparently didn't snug up the bolt tight enough. I also had some wires behind chaincase that were starting to melt at some connectors I had put in after I cut the wires to be able to pull the motor out ( I hadn't researched as to how to to separate the wires from the plug in front of right footwell) so now I'm unsure as to what is actually going on. Whether it was because the ground came off that caused the wires to fry or if its because of the connectors them selves having resistance to the current. So now I have to figure out how I'm going to repair the wires (one broke off and another is close) as there is no room whatsoever to get in there to reconnect them. Looks like the chaincase will need to come off. Those wires are laying right on the bulkhead, perhaps you have a rubbing issue there?
