FD3S Gauge Cluster Problem - Video Inside
Hey guys,
Bought an FD a few months ago and since I got the car, it's had a problem with a non-working odometer, twitchy tach and a speedo gone haywire (but generally mimics tach movement). See video below: The RPM readings on my PFC seem fine, with no "twitch" in the reading, so I am ruling out problems related to the speed sensor on the trans (would affect speedo) or the signal from the coils (would affect tach). I've been doing a lot of reading, and realize there are a number of possible causes/solutions: - Bad capacitors on the circuit boards (Source) - Bad ground, signal or 12V connection problem between clip and cluster (Source) - Cold solder joints on the circuit boards (Source, Source 2, Instructions) Any experts that can weigh in to let me know what they think is the most likely cause before I start opening up the cluster? PS - For anyone looking for instructions on how to open up the cluster, here is a great one (Link) Thanks |
My best advice is to remove the cluster, open it, remove the speedo board, then visually inspect the board for swelled/leaked caps, burned solder runs, and the like found on the threads in this forum.
Look for the DIY How-to Troubleshooting thread for a wealth of info. Take lots of photos and post in the appropriate threads, please. Cheers, George |
