Econometer dead w/ a new SI board, 1990 325is
Hello all!
I just finished replacing my SI board, FINALLY, and to my disappointment, it didn't fix the econometer. It did fix my service lights and the twitchy gas gauge.
I had a NiCad board which had shoddy soldering work on it (which I discovered while rebuilding the odometer), but still had the main 4 gauges mostly working, and I replaced it with a Lithium board which I had soldered new batteries onto. Upon re-installation and startup everything was working perfectly other than the Econometer.
The gauge behavior is sitting nailed past 40 all the time. When opened up, I poked the needle around, it moved freely but slooooowly returned to that position. I could see the gear set moving and no obvious cold-solder joints in the gauge or snapped motor winding terminals.
My question is if there's anything besides changing the SI board or the gauge itself that can get the MPG gauge moving. I've seen a few folks online post that they disconnected the battery overnight and that somehow reset the econometer, has anyone heard of this working?
