DIY FICM repair

Did the ficm repair today. Wasn't hard at all even with my lackluster soldering skills. Seems to be holding the voltage well, guess I didn't screw it up to bad.

Here's the write-up I used. It's pretty good. The only thing I had a hard time with was the goo on the board. Mine was very thick and the hair dryer didn't do squat. And the resistors are small and hard to do. But all in all, not a bad project.

I don't know why the link I attached doesn't go to the right place on the autoguide app, but does on the internet. Strange..

I had a 7.3 and loved it, other than the trans. Till some clabber head stole it.

The small semi conductors with the marking of (Dale0075) can be soldered also from the back of the board. I took my extra ficm and did not remove the silicone based material to get to the topside.
I instead used the soldering iron on the backside adding solder and heating it up until it flowed into all of the small holes that attaches them to the board. The solder will flow right through and reflow on the other side, stop when they are all filled.
Now this only works if the resistors are still intact. If your resistors are burned out like one of mine was on original ficm you can buy them on the web for .49 cents each at Mouser Electronics.

You inspired me. Just did mine. Was just about to send it out to get repaired, and figured 'what the hell'. Was getting readings in the low 20's after start up. Now I'm at fluctuating between 48 and 46.5! I honestly don't even know why this works. I also butchered the hell out of the board (i'm apparently horrible at soldering). Especially trying to solder between those two resistors on each side. But, whatever, I'm back on the road.
