Hi just wondering if anyone has experienced this when I operate the windows it makes the rpm gauge go up. And if I turn the headlights on the temp gauge goes up also wipers and windows are slow

 

From EX Auto sparks...now retired 81 years.....you have a earth problem....engine from standard has the negative of the battery going direct to engine..so should be good...but ensure is tight etc...its the body earths that need looking at...your see a thinner lead goes to body from battery..check if all clean / tight...there are main earthing points behind front speakers on the " A " posts as i remember....but to long ago now...wiper motor base another....best i can help hear. .Peter

 

Do you have an alarm on the car, or i know the clock will draw a very very small current, also the radio will use a little too, I never got to the bottom of my problem I think it is a bad earth somewhere

 

As above the clock can draw small current..also some after market Alarms.....but only small draws on Battery...main item to kill a battery over night is a leaking Alternator Diode....best way to check unplug the Alternator... you should have then just ..2 / 3 ma amps or less re type of Alarm...with a duff Alternator..up to 7 amps....OAP Pete
