The site says 10.5 volts and he was above that while operation. I even had him check voltage at the battery side of the relay and used that power source to operate. It does work off of the field coil generation via reverse polarity.

It doesn't say anything in the PDF about mounting angles so maybe that's not critical. In that case the "Latching Relay" is the way to go!ĭue to its design, I would guess that this relay has to be mounted vertically, as the permanent "N" magnet appears to position itself (closed) by gravity. Some coaches just make it almost impossible to do unless your willing to remount batteries. The problem with the "Big Switch" is location in relation to batteries. As stated earlier I still subscribe to the "Big Switch" in simplicity and being bullet proof in design. Sometimes it just steps up and bites you. I was hoping for a thank you instead of this. The latching relay use and wiring are sound.

But unless I'm standing there looking at it I can only guess about several scenario's on cause of failure.

I would suspect a MFG defect before anything else. The switch is wired correctly and you can hear it trying to unlatch but the contacts are not releasing. hilarlee has overcome the fear and has wired it in like it's suppose to be. The problem with electrical is the fear factor of getting started. I hope there customer support is good and I would like to hear how hilarlee is treated by this company. The link to there battery product page is hereĪnd a link to there customer service page is here I've never dealt with this company before. I didn't see the "Big Boy" until after this thread was underway. It sure looks like it could handle some amps. The "Big Boy" would has a larger plate and bigger contacts for the amp load and maybe a heavier latch assy. The correct backyard terminology is called "Fudge Factor" The big boy cost about $30 more then the 100 amp unit and if you subscribe to the theory principle (pun intended) of bigger is better then that might work better for you. I would suspect the rating thing had nothing to do with it as they only had on the interior light and no other load. They do make a bigger one called the Big Boy that's rated for 200 amps. The one they purchased was rated for 100 amps. Could these relays be under rated for their application? I have been following this thread closely as I am rewiring to eliminate my isolator.
