07 yukon xl, combining the trucks electrical system with audio side..

Recommended Posts

I Have been running my truck and lighting on the stock alternator and electrical system. I have 3 370 amp CES alternators running the audio side of the truck.  07 yukon xl 5.3

I have ordered a 270 amp CES alternator to go into the stock location and I want to combine the truck and audio side so they are not seperate anymore.

Has anyone done something similar and did you run into any issues? The stock alternator is controlled by the pcm and it shows 15.2 volts on the stock volt gauge in dash, at times it shows around 13.5 or so.

From what I have gathered in my searches The only issue i will have is bypassing the pcm and from what I see it only causes a battery light in the dash.

The final destination here is to run all 4 alternators on a adjustable external regulator that is setup to control all 4 alternators and have the ability to shut off each alternator individually...

Keep them separate. Also 15.2 is high.  Do you have your truck side ground ran through the battery current sensor?   If you have a ground on any battery for the stock side it needs to be ran through the sensor or it will cause a high charge like you have now

Didn't do anything...my voltage went to from 13.8 to low 13s.

Then you may want to get a pcm controller.  Because whenever I turned in my headlights on my 07 silverado.  The voltage stayed at 14.7

My Suburban is PCM controlled already. I have 0 gauge going through the sensor as we speak. I might have to start troubleshooting and see where the actual problem is. Ive read that certain conditions "activate" or allow for higher charging such as turning on headlights, driving in tow mode and a few other things.

Why don't you just bypass the PCM altogether?

Yeah, I figure thats the best way to go...dual alts for my setup. 15.3 to the lithium for Audio only. AGM for the stock alt.
