Comments about Sierra Six Gang ATO/ATC Fuse Block, Sierra Part #FS40420:
I was having trouble with all the electrical components on a boat that I just purchased. I traced the problem to a faulty fuse block. This was an exact replacement for the factory one at less that half the price, it even used the same holes for mounting. After installing the new block all my electrical components and gauges work perfectly.
Bottom Line Yes, I would recommend this to a friend
