Winch Power Connections on 5th Gens

[HAL9001]

Many newer RAMs use an Intelligent Battery Sensor (IBS) to monitor battery conditions. In normal operation, all electrical loads in the vehicle pass through the IBS which is located at the negative post on the 12 Volt battery. You're not supposed to connect any electrical load directly to the negative battery post bypassing the IBS.

However, quite a few of us want to install a winch on our truck. A powerful winch can draw as much as 450 amps. A typical IBS has a rating of only around 200 Amps max. So, what are we supposed to do in this situation? If I install my 12,000 lb winch rated at 430 Amp to the IBS, I'm likely to burn the IBS out. This is a 4x4 truck, trucks often have winches. There must be a proper method of connecting a powerful winch to the RAM's battery.

Has anyone who has installed a winch run across this issue yet?

Thanks, I'll try them. I've already asked WARN and they haven't answered.

I don't think hardly anyone knows the answer to this.

No answer from WARN. It appears no one knows the answer.

Any news? I know this is an old thread, but I just picked up a '17 ram, and it uses the same IBS sensor as the 5th gens. I have an auxbeam 60A for most my stuff but I want to wire 40A compressor and 0/1 to the battery. I use the 0/1 for boosting other cars and for my winch. I'm tempted to go straight to battery for my heavy loads, so far my googlefu has mixed responses... some say it's fine, some say it's the end of the world to bypass the IBS for anything.
