Question about RoadPro AC/DC Power Inverter 2000/5000w

2 Answers

I have a 2500 watt roadpro, and would like to no if there is a different way to hook up to keep from killing both of my batteries in my Dodge Cummins. I have a small freezer that I take hunting so I can cool the meat, and freeze the capes.

Refrigerators require a LOT of power. They are one of the biggest energy consumers in a typical household. Although they don't run all the time, they kick off and on quite a bit. To answer your question, there is no wiring solution for your problem. Power inverters are inherently inefficient as well therefore they are actually pulling more power than required to power your refrigerator. Your refrigerators will work while your engine is running (because the alternator is providing continuous power) but as soon as your engine is off, they switch to battery power. If an generator is out of the question, I'm sure you can find larger batteries that could extend the time your refrigerators can run.
I hope this helps!

You can install a battery isolator or battery switch between your two batteries; using one for the inverter and one for the truck. Or you have to get larger capacity batteries.

Dodge cummins tow haul stays on


Hi, I have a 2004 Dodge Ram 2500, 5.9 Cummins with 225,000 miles. Just today, my Haul/Tow keeps coming on and Trans/Temp light. Keeps automatically switching in and out on its own. It's been 100,000 miles since my last trans maintenance. Going to a mechanic close and he suggested to start with fluid change, filter change, and inspect the band, maybe adjust. Trans runs very smoothly. Checked the fluid, looks clean and not hot. Is this common with this year and mileage? If so, whats normally the out come? If the band is bad, do I have to replace the entire trans?

If you remove the fuel pump fuse of relay you will stop the flow of fuel. A simple on/off switch installed on the hot wire going to the fuel pump will work.

If you are running any extra systems, ie amps, subs, high watt speakers, etc. etc. you may need to get a better batter, like the blue. or yellow top one. check with auto zone.

Have several non working inverters


I have had this happen a few times.

Sadly replacement is the Best option.
Repairs can be %75 the cost of a new one.

The best invert we have been using is a Pure Sine 1500 watt inverter.

Sad news but hope this tip helps.
