Title: somethings draining the battery.....
Post by: workhorse '90 8v on 19 January 2004, 19:40

my girlys 90 8v is draining batteries dead within 10hrs...

anyone know any simple methods of tracking down the culprit?

i read in a post someone putting a multimeter across somewhere and taking the fuses out one by one?? but i'm damned if i can find that post again..

anybody got any tips please..... :)

Try topping up the battery with battery water from a petrol station. Did the trick for me :)

Don't recommend disconecting the battery while the engine is running :o. Voltage spikes can toast all your electrics and ecu. To check that it is charging, run the engine and check the voltage at the battery terminals, should be over 13.5 up to 14.5 max. Check for battery discharge with everything off, disconnect the earth terminal and with a meter on amps, one probe on the terminal and the other on the connector, should be next to no currant flowing. About 50 millivolts or less.
