voltage guage fluctuating ?

check your battery terminals torque those bitches down
i had a positive battery terminal that was a teency i mean just a hair lose
and that alone was causing my voltage guage on the dash to fluctuate all over
the place and causing significant volt drop to my amp

First I would take a wire brush and unbolt the two terminals and clean them with contact cleaner and brush any acidic corrosion on the terminals or on the battery plug ins with the cleaner and wire brush and wrench them down tight. You will be fine. If this keeps happening you should investing in a capacitor to run inline+ if it drains that much voltage. If its dropping it to 8 amps to 9 amps you will need a 100 micro farad to keep the voltage stay the same
