Could not having my abs fuse in, result in low volltage in my car, and possiby, speed sinsor warnings periodically?
I'm experiencing low voltage and stalling when i sit at idle over 5 min usually. Idle drops when things are being turned on, ( lights etc) snd does not recover (under 12v till i rev the engine up, or start driving. If this could be a short, whats the easlist way test.

Thanks,
