    Quoted from barakandl:

    I hate assembling these things, specifically the fuse clips. Same reason the rectifier board is kit only. Even the kits are tedious counting out crimps. I'm running low on time and it is a lot more lucrative to focus on something like a MPU.
    I've got a new design coming out with Little Fuse 154 style holders. People will probably fuss about the fuse choice but they are dirt cheap, littlefuse makes quality stuff, and most importantly can be automatically assembled. I left the holes so you can use a standard 6.3x32mm glass cartridge fuse straddling the LF154 holder.
    I still have to order more wiring harness, the wire harness factory just came back from vacation and is slammed, but I plan on offering this again, but it might look a bit different.

    I know all about it!

    I just spent three hours making this one with your board and parts ordered from Mouser and Digi-Key. One of the longer steps was making the bridge harness. It requires crimping connector contacts onto segments of wire. If you’ve ever done this, you know that the crimp is stepped - one for the 3mm of exposed wire and a larger-gauge one for the wire housing. Very tedious, although not as tedious as desoldering more than half of the fuse clips that I installed in the wrong orientation!! I didn’t realize each clip has an inboard- and outboard side! Thank goodness I also bought a solder sucker from Mouser.
    Finally got ‘er in though.
