Warning Cluster Teardown - Corrosion and Other Issues (w/ pics)
I removed my idiot light cluster from my car (86) because I wanted to fix my intermittent clock and intermittent brake light issues (the two things I actually use often). Here's some pictures after taking it apart with included questions. 6 questions to be exact.
Question 1: Is it possible to fix the corrosion in the following pictures? (Pics 1-3)
Picture 1:
Picture 2:
Picture 3:
Question 2: Is it possible to fix the breaks in the circuit board connections? (Pics 4 and 5)
Question 3: Is the corrosion (?) seen on the clock problematic? (Pic 6)
Picture 4:
Picture 5:
Picture 6:
Here's four other random pictures.
Picture 7 is everything that the idiot cluster breaks down into.
Picture 8 is a rusty screw which is one of the ones that held the cluster together. I'm guessing this is a good indication of why I have corrosion.
Picture 9 is a rusted resistor that actually fell off shortly after the picture was taken. Question 4: Anyone know where to buy a replacement?
Picture 10 is some weird lines that are on the plastic from the back of the cluster. Question 5: Anyone know what caused them?
Picture 7:
Picture 8: (apparently my camera got a bit happy with the flash)
Picture 9:
Picture 10:
Question 6: Is it worth trying to fix?

1. The corrosion doesn't look too bad. Clean it off with a cloth and contact cleaner and you will likely find that there isn't too much damage. I've fixed worse.
2. Install a piece of wire as a jumper.
3. Can't see picture #6.
4. That's a capacitor. You can purchase a replacement at any electronics store.
5. Can't see picture #10.
6. Probably.

2. Hmmmm, I can try to do that. I hope trying things 80 times doesn't damage the board . I'm new to soldering...
3. Fixed (I think).
4. Capacitor, resistor, apples, oranges...
5. Fixed (I think).
6. Good to hear. Sounds like fun.

1. It's the one that came with the car and I want to keep everything as stock as possible.
2. It's a project for me. I've never soldered anything like this before (or much in general besides playing around with some wiring to practice). I bought a de-soldering iron just yesterday to do this.
3. I'd like a spare to keep around.

a good way to get the solder out is to get a 'solder sucker', just heat up the solder and the tool will suck it right out. what does your tool look like? ive seen others use like a copper mesh to get it out but i havent had good experience that way. replacement resistors and cap's cost like $.10-$.50 each.

Also, will installing a jumper wire for the corroded areas be a possibility?

Yes, that's how you jumper.
The corrosion around the VFD pins is a bit of a concern, but if the board is still in acceptable condition then you can probably fix it.

And how can I tell if the board is in acceptable condition?
The parking brake light worked sometimes and when it didn't I could slap the dash a couple times and get it come on. The clock was usually on but never showed anything besides 1:00 (except one time it showed 2:00 and one time it showed 0:00). It did tend to turn off when I turned my headlights on, oddly enough.
Sorry for the, I guess, newb questions, I just know nothing (basically) about electronics but I'm trying to learn.
I guess I could of started with easier projects like fixing my 3800 rpm hesitation and figuring out why my voltage drops about 1.5v when I put my car in reverse... but oh well.

with your corrosion, clean the contacts good and hope for the best. If the circuit card and electrial runs have started to corrode, the card will be done. Once all the corrosion is off, check resistance levels on the runs with a multimeter to see if you have any opens (breaks) or shorts in the lines. Good luck with your project.

if i was you, now thats just saying if i was you, i would redo the whole idiot light cluster and remove the pcb.

I think you are salvage the cluster still. It might be a bit of work thou . Althou, I got a used S5 cluster ..hehe.. if you wanna update the cluster a bit :P

Sorry it took so long for me to respond back, but the only way to check and see if you runs are corroded is to check resistance values, if you see almost no resistance you should be good, but if you see huge values thats not good. You just dont check through the circuits, since then the values would be way off. But dur to the age and the pics, the best bet might be to get a new board and go from there.

Also, here's some of my progress. Let me know how the soldering/desoldering looks. Keep in mind this is the first time I've soldered a board / used my desoldering iron.
1. How does the contacts around where the lights were look? I'm assuming that's where the lights connect...
2.
3.
4.
5. There's one spot (about 2/3rds of the way over) on this pic that I did go back and fix. It's where 2 of them connected... so... ignore it.
