Resolved Question:

Mazda 323F. Had a flat battery, now recharged, car starts and drives fine, but instruments not working. Speedo, Tacho, Fuel and water temperature all show zero. Even mileage reads: ------- ! All were working previously before. (Battery discharged because I left map reading light on and car was not used for a couple of days.)

Hello, welcome. My name isXXXXX will do my very best to assist you with your question. I apologize if you have been waiting long for a response.

From what you are describing the issue that you are having is consistent with a dead cell in the battery, and the battery needs to be replaced or the system needed to be reset. What I would suggest as a first step is to disconnect the negative and positive battery cable ends and leave them disconnected for 5 minutes then reconnect and retry. This will reset the system, if the issue continues the battery will likely need to be replaced.

Thanks - the battery was actually new in September 2012, so ought to be ok (but may be faulty of course).


I'll try disconnecting the battery tomorrow for 5 minutes as you suggest (too cold to be messing about outside at this hour!). Thanks for your help. I'll let you know how I get on.

Hi Mike


Just to let you know, I disconnected the battery for 5-10 minutes and then reconnected. Was pleased that immediately a mileage showed on the odo and then, on firing up, I saw all the instruments were in business again. Thanks for your advice - sorry it seemed to be such a trivial issue! I should have realised the first thing to try with computer problems is to "turn it and turn it on again"!
