Stock No idea... Never upgraded though
Generator output? What amp rating do you have now? What amp ratings are there available as options for your truck?
No idea...havent looked
What condition are your battery cables?
Good? Its brand new. Truck is a Year old
What gauge wire was used to carry the power for the insert?
What ever was supplied from truckcraft. Pretty thick.
How long are those power cables?
Maybe 7' just from the insert to the battery.

Combination length and gauge can cause excessive amperage draw causing relays and breakers to trip.

Company that did install uses light gauge wires to save money?

All these things can cause a system wide voltage drop when the insert is used causing relays to trip and trouble codes to be set.

Sounds like i have some work to to tomorrow. Thanks

I have the same truck. I reading on the GM Upfitter site something about a diode has to be installed if you install an something that has draws high amps. It said something about the power surge could damage the trucks electronics. I will post the link if I can find it. If this was the case I would thing guys with plows would be having the same problem thou. I was thinking about putting a insert on my truck in the spring so keep us up dated.

Heavier duty guage battery cables, gen output cable, feed and ground cables, will greatly reduce the voltage drop.

Also higher output gen and largest group size battery will help reduce voltage drop.

Most of the wires i see look pretty heavy duty.... Also I have a Boss V on this same truck and have never had a problem with the truck... But we will see because this is the first year i will have both on one truck.
