PAC SPR200 Dual Battery Isolator & Monitor

It shipped very fast. A 200 amp relay with a controller circuit for $59 is a steal. This was a replacement for a 600 amp house battery bank charging relay on a motorcoach. As it turned out the original (same brand) was still good - the problem was elsewhere. Unfortunately, I broke the housing on the original when I took it off. Even more unfortunately, I broke the new one when I bolted it in. The housing is a plastic-Bakelite material that doesn't tolerate over-tightening of the big transfer lugs. The housing one the new one shattered and the lugs fell out. My mistake - but be careful not to repeat my mistake. Amazingly, I was able to glue the whole thing back together (Gorilla Glue!! Good stuff) and it worked fine. I did order a spare in case the glue doesn't hold - just the relay without the control module - $49. Still a bargain. Even with the breakage and the replacement order, this solution was probably $200 less expensive than the only other alternatives I could find. Thank you Walmart!!
