Besides the obvious best answer of dropping in a fresh 12 valve, do any of you know exactly which fusible link is used for the AMP gauge in this thing?

I've been chasing diagrams to no avail. I know the alternator is putting out, it measures 13.9 to 14.1 at the top of the battery.

If not, I'll just add a volt gauge, as they give a true representation. Just trying to keep it OEM.

Thanks
