No Luck so far making this device operate. I have a 1971 VW Bus and wanted a aux battery for accessories without draining the starter battery. Installation was easy and followed very easily. I have a 7 month old starter battery. Once I hooked in a ground wire from the aux battery to the frame the red blinking light turned solid red as stated in the instructions. I start the vehicle and the blue charging light never came on. Thought, well I will drive around and see what happens. I found out that my starter battery kept draining while the aux batter remained charged...but still no blue light.Basically it has killed my (fairly new) starter battery and I got it replaced - did find out on numerous occasions that the jumpstart feature works GREAT!!! New starter battery in, same thing exactly as written above. Back to square one. Called tech support, "Tim" was very helpful and said it may be that the circuit board is defective and to return it. I did and waiting on a replacement. I hope it works, but the new starter battery has probably suffered some damage from being discharged frequently. Tech support also mentioned that the unit will not work on a positive grounded vehicle and suggested that may be my issue. No, the VW Bus has a negative ground system....but people who may have a European car that has a positive ground system, this will not work. I will update once I get the replacement, but just don't think it is going to work but hoping for the best. The instructions said it goes into charging mode when the starter battery is above 13.4v....well, that is probably the problem as even the starter battery read 12.8 volts BRAND NEW. Not too sure how to get it up to 13.4? Really disappointed this did not work for me so far and caused a lot of troubles along the way. Looks like many people had a good experience. ****UPDATE**** Batteries, mostly the starter battery was low. Decided to put it on a charger while still in the vehicle. Next morning to my surprise the blue LED light was on! Turns out it is working properly, I was just not getting the proper voltage due to a pre-existing alternator condition. Got the alternator wiring corrected and this product works as described and like a champ!

يتركب بين البطاريتين نفس عازل السنيدي ورفيق الدرب وبسعر افضل. يفصل بين البطاريتين اول ماينزل مستوى البطارية الأساسية وفيه ازرار لشحن البطارة الأساسية من الإضافية له خمسة أشهر راكب على السيارة والحمد لله بدون ملاحظات

My previous battery isolator failed. When I looked at replacing it the same make/model I had was only $30 so was definitely cheap & nasty. I bought this WirthCo item based on other reviews. Installation instructions were dead easy. Item worked first go & hasn't missed a beat. Similar devices were much more expensive so this was good value for money.

I previously used a cole hersee on my last truck.it worked great but required external switches and led. This unit is smaller, cheaper and required no extra switch or light. Seems to work great and is electronic vs solenoid so time will tell Very pleased so far 2020 chev. suburban, install required 2 x 150 Amp breakers plus 30 Amp breaker hard wired to trailer feed. The second battery in the truck powers and recharges my trailer battery and allows effectively endless use as every time we drive the truck it recharges the battery and then we can reconnect to the trailer using extension cable the ability to boost the truck is a nice bonus which saved me on my last truck as the battery aged but this one is still young and the battery isn't dying yet update.. year later 8 camping trips 50,000 kilometers more on the truck and this unit is working great very very pleased

Just purchased a solar system for the caravan and this product was highly recommended to compliment and stop battery drainage. The product is as explained and is of good quality .
