One day last winter I started to pull out into an intersection only to find out that it was slick ice under the snow (I was even in 4X4 at the time). Unfortunately I was beyond the point of no return and it was either get moving or get smoked. I was in second gear and knew I would not have time to grab third on the NV5600 so I just floored it, I know that is not usually the best way to get traction, but desperate times call for desperate measures. I made it through and just as I let up on the go pedal I had a look down at the tach and it was dropping through `3750 from I don't know what RPM and the parking brake light was flashing, it kept flashing for about 10 seconds before it went out (scared the **** out of me I thought I had broke something). Has anyone else had the parking brake light flash, what RPM is it programmed to come on at?
