A word of caution regarding truck powered winches.
The 1500 Intelligent Battery Sensor (IBS), module attached to the battery negative post, can be an issue for winches. 9-12K winches can pull upwards of 400 amps. Bosch, the IBS manufacturer, rates the 1500 IBS module at "approximately 200 amps". They were unwilling to provide exact specs. If the winch negative is attached to the IBS post, the IBS module could potentially be damaged by current demands beyond its design spec. The alternative, attaching winch negative directly to the battery post bypassing the IBS, could adversely impact IBS function.
Inquiries on this matter to RAM Corporate by a couple of us on this forum have essentially been ignored. One RAM response "ground the winch to the engine" is remarkably bad advice as this places not only the IBS at risk but also the engine-battery ground cable. The Vice Design (video above) guys are aware of this issue. You can read an exchange in the comments section between a couple of us and Vice Design in the video below.
Working through Warn Industries, we were able to identify the Stellantis IBS engineer. I sent him a direct email 3 weeks ago addressing this issue. No response to date.
