Just some good info for guys with airdogs, (not sure if this has been discussed yet). After melting fuses and the relay on my Airdog II wiring harness, we had a discussion with the engineer of the Airdog. Apparently early models used 14 and 12 guage wiring for the harness. The 14 guage wiring is not sufficent for the power draw necessary for the airdog. The thing spins at 3000 rpms! So if you have thinner 14 guage wire, either call them for a replacement harness (if in warranty) or replace the 14 guage with 12 guage. This is very important especially with the powerstroke. This will cure issues with the power supply and fuel issues.
