/Hey peoples.
I havent posted on this website in almost two years i think. Its been a while. Anyways, I had a resistor burn out on the SI board of my 1987 325, and the color codes to the resistor are gone. So I was curious if anyone maybe had a good close up picture of a '87 325's SI board? I have been searching around on the net for the past few days and no luck. It would be great if I could find a circuit board schematic for it, but I doubt I will find one. Oh this gauge unit is a MotoMeter one, not a VDO. This is a Base model 325 that I believe was made in 9/86.
I understand that even if I fix the resistor that it just may fry again. But alteast I can start narrowing the problems out. I dont want to spend the money to just buy a new one, even though I can buy one from my local parts guy for $115. Here is why: I am currently in college getting a degree in digital systems technologies. I have allready covered resistors, capacitors, transistors, diodes, and such with my classes, and six months ago made my first 120AC to 12DC power supply. I designed and etched the circuit board myself. This SI board is just a challenge for me to diagnos and fix, its a great way to learn how to fix other circuit boards and such, wich is what I will end up doing after college.
Any info on this would be appreciated guys. have a good one.
