Grounding points

Post by cptnsolo77 » Tue Jun 04, 2019 8:20 am

Long story short, I went through 2 alternators but they both dont seem to put out the proper voltage with ALL the accessories on ( 13.5V) I used to get high 13V - 14.1 with everything on. When im stopped at a traffic light it drops to 12.7V. Im suspecting a bad ground. Battery terminals are clean but im looking for a diagram of ALL the grounding points, Cant seem to find anything online for some reason :roll:

The attached pdf for an 03 Matrix supposedly shows ground points in triangles. I have a hard time spatially relating these 2D diagrams to the 3d physical car, but maybe it will help
