Auto Drive Circuit Analyzer, 1count per Pack, 4.37in Height and 2.38in Width and 2.86in Depth

This told me exactly what the issue was with my wiring. It's a little bit pricey for what it is but very helpful if you own a camper or Rv.

This circuit analyzer works exactly as advertised. It is very easy to use and gives a clear reading right away. It's a great tool to keep in the vehicle for troubleshooting and ensuring everything is wired safely. Definitely worth it for the peace of mind.

Works as advertised. Plug and play!

Small and handy for a surge protector👍

Works great. Compact size.

Good product and cheaper than anything else I could find. The indicator lights make it easy to see how the circuit is performing at a quick glance.

Over time, this will save you a lot of money in electrical repairs. Better to damage this surge protector rather than your RV’s electrical system. I use this as the first line of defense prior to connecting the rest of the RV’s power cords. This tells me if there is a problem with the electrical box in whatever park I might be at the time. It is surprising how many parks have messed up electrical boxes. This saves your RV from being fried. It also saves very expensive surge protectors from being fried by faulty wiring in the parks. This is a fantastic first line of defense.

If you know how to properly use this circuit analyzer it is a valuable asset to have with an RV. We've used it a few times now and it was pretty easy to use. We were able to locate and correct some incorrect wiring that was tripping the breaker in our RV with ease thanks to this handy tool. Just be sure to follow all directions and safety precautions when using it. Overall it fits in my hand easily so it's not oversized making it great for keeping with you all the time.

Simply plug and begin to test and protect your rv's electronic devices and systems. Diagnostic lights warn of faulty wiring before you plug in your electrical cord. Not compatible with any type of adapter, must be hooked up to 30 amps directly. Constantly supplies power regardless of a spike or surge, no manual reset required. Cuts off if high or low voltage

Great for if you're in a pinch but not long term
