New Universal Power Distribution Block (Junction Block) Works

    I haven't been logging like I should.  We had a little trouble with getting the replacement power distribution block at Advance Auto Parts in Woodsfield, Ohio because of the Labor Day weekend coupled with a day off by the 3rd party regional distributer taking a day off after Labor Day which the staff at Advance didn't know about.  There was some concern about the part being so small that in transit, it could slide around these personal vehicles transporting and cause it to slip into a crack or get hidden under a seat somewhere.  So, the employees ordered another one from another distribution point just in case.  Whatever ended up happening, I received this power distribution block on time as revised.

    I replaced the stock power distribution block in my 1987 Chevrolet (Chevy) G20 Sportvan with a Carquest Premium BWD JBA1001,which is not exact, but I got the van started with it nonetheless.  The part is also known as a "junction block."  I had to cut the wires out of the old one because it's poles were rusted.  When I tried to loosen the nuts, the bolts just turned.  And the other side was behind some tough plastic that I wasn't able to cut with a razor to try and see if they had bolt heads in order to use a socket and a wrench to force the nuts to turn.  That's when I decided that this thing just has to go.

    I like the new block.  I used 10 gauge wire and some 12-10 terminal eyelets to jump the 12V power coming from the battery/ alternator from bank to bank to make it all work.  The stock one did this by way of a small brass plate that was mounted at the bottom of the old block's bolts.  I'm glad that I waited for this part because I was orginally going to fabracate one myself using a plastic container for some midget wrenches that I recently bought.  But as mentioned in a previous log that I was concerned that the plastic wasn't the right grade.  And with 12V at anywhere between 30A to 80A, 300 - 960 watts being channeled through it, that the new block would melt, or worse yet... catch fire 😟.

    So, I turned the van on and it worked.  I then moved it forward about 3 feet so that it looks like it moved.  But on another project, I think I broke off a bolt and it slipped off inside the intake manifold?  And I might be taking that off and go looking for it?  But when I pressed the accelerator pedal, I didn't hear anything rattling, which to me suggests that there's something else wrong?

    I am a backyard mechanic.  This is Matty DIY.  I am not certified, nor have I ever worked in an automotive repair shop.  I thought that all of you out there watching these logs should know this.
