After adding the led brake lights and flex-a-lite electric fans, I noticed the voltage meter on the truck drop below 14, before it use to stay .5 to 1 bar above 14. Lately, it goes 1 -2 bars below 14 as soon as I turn on the parking lights and also drops a little more when I turn on the a/c and the e fans kick on. I did upgrade the alternator to a 140 amp about a year or 2 ago.
I started the big 3 upgrade this weekend with the ground wire from the battery to the motor. The voltage increased slightly and the meter remained steady. Yesterday, I added the ground from the battery to the fender and the power wire from the alternator to the battery. When I start the truck in the garage and it is sitting still, the volt meter is fine. However, when I start moving, the needle starts bouncing/ vibrating a little (back and forth between 2 bars on the meter). Also, when I rev the motor, the needle vibrates, when the motor comes back to idle, the dash lights dim and the meter drops 2 bars for a second and then jumps back to 14.
First, I thought it might be the ground from the battery to the fender, so I removed that wire and took it for a drive. I had the same results (needle bounces). Then I put the ground back and took off the power wire. The needle bounce disappeared. I could rev the motor and the needle would not drop and the lights did not dim.
Does anyone have any ideas on what I might have done wrong? I used 0 gauge fosgate OFC wire.
