I bought a M50 swapped cabrio last week site unseen so I honestly don’t know too much about the history of it.
All the gauges on the cluster work EXCEPT the tachometer. The PO also had shift lights installed by innovative goods. That and the mpg gauge don’t work since they are tied in with the tach.
in addition to this I don’t get any si board lights on start up. Not does anything besides battery light up on the bottom row. (Check panel has like 4 things lit up)
I pulled the SI board and to my surprise the cluster was refurbished by BavRestorations in 2016. I tested voltage on the 2 batteries which were the late model AA size ones and got 1.25 volts on both of them which is right in line with what it should be. I took pics of the board and nothing stands out to me as bad or out of place. No visible burns or shorts that I can tell. I’ll upload them from my phone as a reply.
i did swap fuses 10, 12, 21 since I had a bunch of 7.5 on hand.
im about to bite the bullet and mail the cluster back to bavrestore because I just can’t figure this out. Any ideas ?
i get no lights from cluster in key position 1, when I start the car I get a faint glow in inspection light, and I see the tach needle move up and back down, but it quickly goes away.
The PO had a bad car battery in there before and told me he jumped it a few times to drive. When I purchased the car I brought a new battery.
