Nice Product

October 15, 2012

This product functions as specified and has worked as planned in isolating via key on/key off a 400 watt power inverter. It is well made and appears durable. I would recommend this as a good isolator/relay solution.

I have only two complaints with this product: 1) There are no instructions, basically pretty strait forward IF you understand some basic principles but could confuse a novice as to what wire to what post. and 2) There was no cover for the large 12v battery posts. This could cause a great hazard if something was to contact them and ground. A plastic or rubber cover would have been nice (I made my own).

Overall a good buy.

works perfectly

August 15, 2012

I was going to use this in my sister's car stereo system, but had to install it to her fans instead since her a/c went out 2 days before the product showed up. anyway, I am very pleased because both fans work fine, and no power drainage issues. great for any amplifier or fans that have an 80 amp draw. just make sure you fuse the positive line to the battery or batteries. oh, mine didn't come with markings for the two smaller posts so had to get diagram from a stinger isolater of same style. great for the price though... will buy again once i jump on these re amps for my sis's car (overhauling the system). A+

I purchased the ib80 amp battery isolator relay and installed it on my car it will open when i turn the key on but will not shut off when i turn the key off. is this a machanical switch and is it possable the unit is bad? it woill click on and off if i don't start the car. buty if i start the cat it will not shut off the car unless i tap the unit. any advice?

Best Answer: Absolutely,
For sure that cable is keeping energized somehow and that's the reason for it to malfunction. You have to make sure that any other source of power is keeping that cable energized. I did installed mine a as transfer switch for two independent batteries on my jetSki with a manual toggle switch for on & off of the BAY IB80. Hope this work out for you!!
