help with weird dome light problem
I have a 68 malibu and i am having a problem with my dome light and oil pressure light.
I ran new hot and ground wires to the dome light before I had my headliner installed.(I know that the ground is what is broken by the door switch) everything was fine until....I installed a console and hooked up the wiring for its light. I ran the console lights hot wire directly to the side of the fuse box which is hot all the time (not controlled by the ignition switch) and hooked the ground wire into the ground wire I installed for the headliner dome light. Every thing works fine, but now my engine light comes on! It will do this intermittintly even with the engine off and no key in the ignition. Needless to say this runs down my battery. Must be a problem with the ground somewhere. Hopefully someone here can give me some possible things to check. THANKS!
