Do you have problems with your (late style) SI-Board?
Did you check the voltage of your Sanyo Lithium CR14250 batteries?
Are they far below 3.0V? Then it’s time to replaceme them!
This is a set of the correct lithium cell’s for the later (1986 and on) BMW E23 E24 E28 and E30 instrument clusters, with the lithium cell’s. They do NOT replace the old style NiCd 1.2V batteries!
If you need confirmation or more info just email us (with pictures of your old board please)
Make sure to double check which type of cluster board you have, counting the RED number of LED’s does the trick:
3 RED LED’s in the line of 5 green and 1 yellow means you have an early type 1 cluster
1 RED LED in the line of 5 green and 1 yellow means you have a late type 2 cluster
Feel free to ask questions!
