12v erratic tach and dash lights.
So about a month ago my trucks tach started jumping on me as well as the CEL, Gen, WTS, and CC green light. It's fine at idle, it blips when I drive though, bumps really throw it through a loop. I unplugged my ess and it just made it where any throttle throws the lights. I'm at a complete loss. Bad ESS? or am I going to be spending hours tracing wires to find a short or bad ground. Also my ABS and brake light are always on any info on that would be great. Thanks in advance . I'm tired of watching it go crazy.
