T4 oil pressure light and rev counter

[nofear]

Hi all.

I have a problem and its driving me crazy.

Couple of weeks ago the alternator went on my 2000, T4 1.9 TD. At the same time the rev counter started jumping around and the oil pressure warning light started flashing and beeping.

I got the alternator fix (I also had to replace the battery).

The rev counter still doesn't work and the oil pressure light still flashes.

Any ideas?

Thanks in advance.
