    It's a good thought! I was having major issues with this truck starting so when I was diagnosing that I went through and cleaned all the battery terminals and cables. I didn't do the connections at the fuse block though. Might have to take a look at them and see what they look like. Thanks!

    Im having the same issue with my 07 Volvo VNL 670 D12D engine brake. Pulsates on and off constantly when applied. Also my idle increase periodically doesn’t work with the cruise control. I’ve been having a problem with the 20v fuse that’s connected directly to the battery which I believe goes to the ecm. Sometimes my truck won’t start and I have to pull it in and out. Need to replace the harness or clean it. Anyways did anyone ever figure out the engine brake problem here?
