Losing voltage???? What could be this then...

Ur not loosing voltage , it's because at idle the alt outs out less than at cruising speed ( around 2k rpm), every alt has an idle rating and a higher ROM rating . Its normal, I'd suggest charging the batteries overnight on 5a or so bc if they were run low when the alt wasn't working u could be less than 100* voltage. Jut my two cents tho.

2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears. All done by me. stereo is Pioneer avh 600ex, all stinger rca, jp23 v1.5, skar rp150.4, and hertz hpd4. 2 SHCA 6.5 8ohm, 1 SHCA 3.5", and 1 DS18 tw120pro in each door. The 3.5 mid and 3.5" tweeters are powered by the skar rp150.4, the 6.5s are powered by the hertz bridged @4 ohms. Dual runs   of 3/0 welding cable, 300a alternator, 2 Vmax AGMs up front. current sub is a AB XR 12 ( dual 2 ohm) with bottom spider cut out in 2.25 cubes at 32hz

How I know if a Diode dead or bad I put 2 in line with the sense wire upping the voltage. Been on the electricial sense wire for the alt for over 10 years

And put a sealed enclosure in your trunk cut a hole in your deck and call it ported :lol2:
