Electrical problem
I have Buddy working on a ford ranger about a 1988 that shuts down when you hook the amp gage wire up.The Alt has 2 plugs which the amp gage wire runs from one of them,the wire runs from the alt to the gage & from the gage to the ign switch.the Ign has been replaced,the alt & the Inst.panel has been replaced.The truck runs fine until you connect the amp wire & its like you turned the key off.Anyone experienced this problem? I appreciate any & all help--
