What to do if my Sullair 300HH Air Compressor engine does not crank or start?

If your Sullair Air Compressor engine doesn't crank or starts, check the battery cables and tighten them if they are loose. Also, inspect the ground wire for secure attachment to the frame and tighten if needed. If the issue persists, recharge or replace the battery. Examine the fuse in the wiring harness and replace it if it's blown. Check the instrument panel connectors and wires for loose connections, breaks, or corrosion, and reattach, clean, or replace as necessary. Finally, a faulty SSAM module may also be the reason, try to replace the module.
