Ignition Ballast hot!! and i mean hot!

15 is pretty much the high end. What is causing this is almost always voltage drop in the harness supplying the VR. One way to fix this is to break the dark blue (or other color) "ignition run" IGN2 coming out of the bulkhead into the engine bay. Use the firewall end to trigger a relay, feed the contacts power through a fuse/ breaker off the start relay "big stud" and connect the switched contact to the engine bay end of the cut wire
