Battery issues

[bluestreak56]

Im not sure if this issue is compounded by or is causing the battery drain issue im experiencing but currently my MFA is returning some correct and some incorrect figures.

Miles Driven
Average Speed
Average MPG

Are the results all coming back as 0 or near to.

I have obviously been disconnecting the battery alot recently and have disconnected fuse 3 to see if this would help.

The last time these instruments seemed to be working correctly is before my battery change on the 16th December.

A week later when I drove to a Mini Meet in Cov the MPG started at 10 and kept declining till it reached 1.

Anyone know what could be the issue - all the tube lines seem ok or is it just the drain on the batt is causing it to go haywire?

Thanks.

The battery issue Im experiencing is a drain while the car is standing. Not sure whats causing it - have removed the stereo.

If the fuse has gone for the MFA and clock etc would this cause the drain do you think?

First step would be to get the battery checked (even though you say its new) as it might have been a duff one.  Halfords check your battery for free.

pull the clock fuse or battery -ve for 30 seconds, that will reset the clocks.  They really dont like loosing power.  That being said all the functions you mention are controlled by the speedo sensor in the back of the clocks, maybe this has decided to pack up!

Cheers rubjonny - I've disconnected the battery numerous times recently (when its been low on juice) sometimes for overnight periods but still no good.

I'll try and check the sensor behind the clocks if I can get them off..

cheers

Check the flat brown earth cable on the head, near the dizzy. My Dad's had similar problems and once that was cleaned up everything worked fine.

Its not the negative battery earth cable you're referring to is it? (This connected to my geabox housing)
