2000 ML320 Instrument gauges don't work

Hi,

I removed the positive terminal of my battery to clean the post of acid and now the instrument gauges (gas, rpm, speedometer, drive indicator) doesn't work. Lights on the instrument panel work and the car starts and drive but the meters don't work.

I checked the fuses and they seem fine.

Anyone has experienced this and know the fix for this problem?

Thanks.

Gauges work now....

This is my mistake. It was dark when I was working with the fusebox. When I took off the fuse from F16, I mistakenly put it back in F18. So the gauges not working was caused of not having a fuse in F16. All gauges work now and no damage done by disconnecting battery positive terminal first.

I think my A/C compressor locked up and was the reason why I inspected F16. My local tech will look at it.

I still have the dreaded BAS/ESP light on. I ordered the ABS pump carbon brush to see if it will fix it.


Regards.
