Got given this celica a while ago and it was running mint then gave it back to the previous owner as he needed it back....he has now gone overseas has has given the car back in my hands but i cant get it to go properly...
now to cut a longer story short heres what happened, the battery went dead when he stopped using the car so he got a new one...he put it in backwards (polarity wise)...didnt realise until i had went over and checked to take the car...put it in the right way and it started but then died out overnight.
jump started it the next day and i think they werent jump safe cables or took them off in the wrong sequence? cause as i took them off and the cars mirrors, heater and wipers went on and off like crazy but i drove it home like that anyway.
ive charged the battery numerous times now but it keeps loosing charge and now it looses charge after u turn the car off!, also when driving it the rev needle goes crazy at around 5000 revs and looses power??
im guessing it could be a number of things like ECU, altenator and a relay for the power drain?
well what can you expect for a free car i guess? but i would like to use it for a daily driver.

any help appreciated and cheers in advance

Cheers again,
Richie
