Fixing the wiring of my tach - I'm dumber than a blonde!

REOPENED!

Well, it ain't over 'til it's over. I don't know if it was working completely correctly after re-wiring or not. But I noticed over the weekend when driving it that the tach will not go over 2,000 rpm. Right on 2,000 rpm it just refuses to go further. It will bounce around from 2,000 some also, when I'm steady cruising above 2,000 rpm.

So, as I was out, I decided to mess with the wiring. The illumination seemed to be working fine, so I thought it was a grounding issue. I placed the ground at another location, no change.

And subsequently, I got gas. After filling I noticed the gauge would not read full. It would stay just over half. Later I pulled the connector off the ACC fuse tap to check the fuse tap to make sure it was still located properly (and it was). But while under there it appeared that the wire was chaffed from where it ran through some brackets. I rerouted it. But it still won't go above 2,000 rpm.

I'm thinking that wire is compromised now, so I'm going to replace it. After rerouting the wire, the fuel gauge works fine. Very strange. It could be the fuel gauge is not related ... but it is very coincidental.

QUESTION: Does a chaffed ACC (switched power) wire sound like the likely cause?
