Default Anti lock problem

I used a fast charger to start my vette tonight now my anti lock light is on and the ABS is not working I got the car to about 40 stomped the brakes and they locked up and smoked the tires. I just read in the shop manual not to use a fast charger to start the car because it can damage the ABS but it doesn't say what or how. What could I have broke?

Probably the ABS control module (computer). There are 3 relays. You can pull each and test them with the diagram and multi meter.

The only tire locking up is the front drivers side from what I understand there is one relay for each front tire and 1 relay for th rear tires. How hard is it to replace a relay can it be done or will the whole control module need to be replaced

Two relays are mounted on top of the pump. The other is upstream of the harness but everything is still inside the ABS compartment. Located behind driver's seat under cargo area. On a vert, it's under the speaker. Your shop manual shows everything.

From what I've read in the manual if there is a problems with the control module the whole thing must be replaced.
