Running Light Function of 2004 Chevy Trailblazer When Flat Towed Using Roadmaster # RM-154

Question:

2004 Chevrolet trailblazer, 2002 Dutch star motorhome. After this kit is installed I realized if to turn on tail lights on trailblazer and turn on tail lights in motorhome at the same time the diode would be getting two different 12 volt power sources at the same time. Will the diode handle this and work properly, or will diode fail?

The Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 is designed to allow your 2002 Dutch Star Motorhome to power all the lighting of your 2004 Chevy Trailblazer when being flat towed. You should not have the running lights of your Trailblazer turned on independently of the running lights of your motorhome when connected. That could cause the diode to fail but the kit is rated for a max voltage of 24V and max amperage of 85 amps, so it may function even under those conditions.
