Changing Dials

[Guest ian luxford]

thanks for that ian i couldnt see anyother way of connecting the volt meter but the 2 insulated connections did confuse me! it reads the correct voltage up till the rev counter hits 3500 then that and the temp gauge move a lot higher both then stay there till you switch the engine off all very strange

Correct reading?

The voltage should be 12 to 13 volts with the engine stopped.

Below 12V indicates either a flat battery or one with a damaged cell.

With the engine running the volts should be in the range of 13 to 14.2 volts and should hold steady through the rev range.

If the reading goes above 14.5 Volts then the alternator controls are blown or there are earth probs.

 

Check the normal probs. FIRST is there a good (large) earth connection from the engine to the battery and to the body? Are the connections clean and tight? Is there paint/rust in the way of any of these connections?

 

Only then should you start looking further.
