My problem is not with the mileage, it's with something on the circuit board of the speedo. when I attempted to install the unit, smoke came from the connector and some of the copper circuits on the back of the cluster (ribbon tape) got real hot and opened up. Not a good sign! I desperately need a detailed schematic of the entire cluster so I can better diagnose the problem (replacing diodes, chips, etc...), if that is even possible at this point. I thought that maybe I'd be able to swap the entire speedo (minus the face) from my old one with the new one that doesn't work. If this will work then I'll do it, but other than that, I fear that I'm out the $$$ I spent on the damn thing as the person I bought it from won't warranty it or give me my money back. Can anyone else offer any help with the schematic? Thanks!
