Hello all. I'm looking for some insight on what might be causing my forklift to act up. I have a Clark OP-15 (Couldn't find the exact model listed in the Clark category), once energized (for lack of better terminology) while trying to move forward or backward the energizer button in the motor area pops and the machine is disabled? We have not had any issues with the forklift prior to this, although a technician did inspect the machine and stated our charger may be too small for the batteries.

Could anyone who is forklift knowledgeable please help with my troubleshooting?

Thanks, Chris
