Does it bog down? if so have engine checked for ability to deliver HP. Cylinder compression, leakdown test. When was it tuned?

What do you mean you can't connect? Do you mean the in home monitor will not communicate with the unit? Be more specific or send an email to www.advanced-power-technologies.com they are Cummins Power Generation specilists !
