Any body got idea
Not to be insulting but you did turn the master switch on? What generation of 980? Battery jumper and crossover cables are good? Any clicking or lights at all? How do you know the batteries are good if there's no power, did you measure voltage on each one, or all of them together?
The last generation of loaders had a 100 amp bus fuse in them. Batteries would be good, light would come on and it would die in the start position. Id check for breakers as well. Push all the blue buttons even if it does not look tripped. If it clicks, that is where I would look.
Not trying to be a jerk but to just say Cat 980 with out a hint of the s/n range is about like saying My Ford truck won't start. Well it make a big difference if it's a 1930's Model AA or a 2015 F450 Diesel. Give us a little more information and I'm sure you will get a much better answer.
