hello;
i have a msd 6al box in my car, i went to start the car today and it wouldnt fire. after doing some checks i noticed that when i turn on the power source to initiate the box i noticed it wasnt making that slight clicking sound like it normally does, i checked the power and ground source and everything is fine. later i hooked up my friends 6al box the same way and the car fired up.

my question here is. is there a fuse in the box that can be changed or is it a sealed unit that has to be sent out to be rebuilt, if so how much to rebuild it?

Most likely you will need to send it out if it is not a connection issue. They are sealed units
