Not sure what’s wrong, but the auxiliary battery isn’t charging from my main battery. It is actually draining the aux battery.

Due to a fault of my own, my existing isolator failed. After a bit of research, I ordered this model, the read out intrigued me. It has been installed and works as billed on line. The digital readout is easy to read, has a manual and automatic function with the readings coinciding with a multimetre, happy happy. Just that little extra peace of mind.

I use two of these units on my sailing catamaran. They are wired so that when an engine charging voltage is greater than needed for the starting battery the voltage sensing relay automatically connects to the house battery bank.. The voltage display is an added benefit.

Après moins d'un an d'utilisation, il a rendu l'âme...Semble être les relais à l'intérieur qui ont lâché...J'en cherche un de meilleur qualité!

*Edit 6 month update: well I've had it in use under the hood of my truck for six months in actual use now. Sure everything it claims. The connection terminals are a bit small for the correct guage of battery cable. So that could be improved upon. It definitely is sealed against the elements! I've had this mounted up high on the firewall and still has seen water submersion off-road and been hit with engine degreaser and soaked half an hour before being pressure washed numerous times now. Digital display is bright and easy to read, goes dark on standby until you key it to display the voltage. I've discharged via 10k lb winch several times and no issues with back feeding. It does exactly everything it claims. Installation was simple and straight forward with the supplied instructions. Only hitch being the terminals size is a bit smaller than ideal and I did have to cut open the housing slightly further for the heavy 2 gauge copper battery cable required. I'm using this device at it's rated capacity, lower rates useage this would not be an issue with the cable terminals dimensions.I'm happy with my purchase. I'd buy this again.👍Original review: Well I ordered it while on vacation but didn't have time to get it installed for our family off grid camping trip. So it's got two thousand kilometers on it just sitting in the glove box.☹️Quality of the casing fit and finish looks exactly as advertised. Doesn't feel cheap or junky as I'd feared it may. I've held others at the marine hardware store but they didn't have this high a rating. So I have actual in hand product comparison experience with these isolators across a fair market segment. This feels decent build quality compared with those. That's all I can say about it. Shipping was exactly as predicted, within the GTA (greater Toronto area) that's to be expected.I'll review this properly once I've got it installed and in daily use.

Protège à merveille ma batterie de démarrage de se vider avec les accessoires. Coupe a 12.8volts tel que décris. Parfait pour ne pas rester pris au milieu d un plan d’eau.

I received this today and I haven't tried it yet. I will update this review when I get it attached and see if it works. Right out of the box it's missing the attachment bolts and the instructions. The instructions are pretty simple and are posted on the listing sight. Other than that it looks nice and solid and well made.I received an email from the manufacturer stating that the attachment screws were inside under the plastic bottom cover and that they warrantied the item for 12 months. I removed the cover and found the screws as stated. I would like to apologize for my mistake. When I popped off the bottom I found all the required screws and the connector exactly as stated. If I would of been installing the unit right away I would have found them.AGAIN MY MISTAKE. I appreciate the fast response from the manufacturer regarding my concern. Thank You!
