Dennis the original battery was a 6.0V 620mAh so you need to tell us what battery you are putting in. After that you need to use your multimeter and check for the power leads etc. going to the main board. Without the basic information we can only guess.
Apparently the Landshark was known for very poor battery life

It's a 6 volt system and you used a 8.4V battery? Check your power board for burned components (you will have to measure the values ) and check your motors to see if they are still working.
