Do you see how the left side of fuses #1 and #2 are joined together? Do you see the yellow and red wire both are soldered together on to the top screw to fuse #1? Yellow goes to the ignition switch and RED goes to the amp gauge (orange goes to the alternator). The red wire is what you want to snip along with the top lead to the circuit breaker. That red wire is fried up under the dash. This is really an easy fix, much easier than you think. And a voltmeter is just a simple two wire run.
