strange way to save $

[kentannenbaum]

I've got an '89 535i. The temp and fuel guages went down and I thought I had an instrument cluster problem OR a circuit board issue. I actually purchased a board and luckily they sent the wrong board. A few days later, I left a light on, the battery dies and the next day when I jumped it, the gauges work! There may not be a connection (excuse the expression) but I
don't get it...that it, if there's a connection at all. Thanks.

Hmm, Have you had the alternator tested? Ive had an alternator go, and after the gauges went down my battery was pretty much dead.

The battery is fine. I just drained it inadvertantly and when the car was jumped the gauges worked again.
