TheShanMan's Defender restoration - New repro wiring harnesses!!!
SirPeale:
The thing that's hanging down is the width coil. As long as it's not totally broken or touching anything, it'll be fine.
Looks like you're getting rug pattern in that last picture. That's a good thing.
I'll bet you have at least one bad RAM. You should switch it over to 4164 anyway. More reliable. I'll be offering a 4116 --> 4164 converter in the very near future.
Check the bottom of the cab, you might find some 4116 in there to see if it's running OK. Stuff in bags = likely ok. Stuff on the floor = blown ones that have already been replaced.
Feel the RAM with your fingers. A dead giveaway that a RAM is bad is they get HOT!
I'd recap the power supply. Heck, I'd recap all the boards. The caps are almost 30 years old. They're due.
SirPeale:
Oh yes...I've seen worse corrosion. You need to nip it in the bud, though.
Take out the board, and start LIGHTLY brushing the corrosion with a toothbrush dipped in vinegar. Yes, vinegar. It'll fizz. That's fine. Wipe it with a damp paper towel and dry well.
TheShanMan:
I couldn't see any chips labeled 4116. Which ones are they? I felt every chip on all the boards, and none felt hot. I am curious about a seemingly missing rom chip in picture 3. Is that normal?
I pressed that momentary switch on the sound board, and a couple of minutes later it started playing some music, followed by an explosion sound, and then repeating over and over. What does that mean?
I looked at that dangling red wire, and it connects to one of the terminals for that dangling coil. What am I supposed to hook it up to?
Ummon:
Very nice condition. Quite worth it.
