My tach died the other day on my 1990 325i and I think
it was because I was messing with the wireing and shorted something.
I replaced all the fuses that blew out. Re-wired everything back how it was, nothing, so I took the cluster out and no loose connections either.
Now I'm left with the battieres.
Do I need to charge them before I put them in? Has anyone here done this before? Just any rechargable AA right?
PS: Everything else on my cluster works except the tech.
