Trouble with voltage drop

[leftybass209]

Update: the issue is fixed.

It wound up being the fuse panel power wire being too long. After taking the suggestion above of moving the sensing wire, i still didn't move the harness feed. The excessive length was enough to cause a significant voltage drop on all accessories that got exponentially worse as accessories were added. I bought larger packard terminals to run a larger gauge wire into the factory harness, but it physically didnt fit between the plastic and lock in, so my wire was limited in gauge.

I still have some small stretches of cca wire needing to be replaced bit overall this has made an amazing difference on voltages seen at the accessories.

I discovered this after reading the M.A.D electrical page regarding chevy wiring harnesses.

Thanks for the suggestions
