Install Instructions Note for Dual Battery Isolator Switch # 3376391050

Question:

I purchased one of these and noticed the instructions which came with it said to connect negative cables to posts 1, 2, and common. I did not think this sounded correct and called Wirthco customer service. The engineer I spoke with told me that the instruction card was printed wrong and that it should say positive cables to posts. Luckily I did not follow written instructions. Just wanted to make you aware.

Thanks for passing that on! I hope they fix the instructions going forward so I am going to post this on our site so that it might help future customers as well.
