My 40 has a 10 space fuse block. It also has a 12 space terminal block. I am replacing the amp Guage with a voltmeter. Question is the amp meter had a hot wire from the starter. I believe the ammeter fed the fuse block. Where do I put the starter hot wire on the terminal block. Shows to be a 70 but the fuses and terminal don't match 70 schematics.
