Tazrolla Posted February 14, 2013 Report Share Posted February 14, 2013 I have just put another 4age engine into my ae82 and it purred like a kitten for a frw weeks however the battery i had in it was farked and (don't ask me why) but i tryed starting it quite a few times on the farked batt, i have since tryed the batt out of another car(fully charged and in good working order) and now the rolla work start via the key... It will start when i roll start her but it runs poorly and i have noticed that the tacho(in dash one) behaves weirdly(shows less revs when i rev it) it also when engine is stoped and i go to start her i have noticed that the engine light and oil light are dim as i turn keto pre start position... I am thinking i might have damaged the ecu from trying to s atart her with a farked batt... Any ideas ??? Maybe a bad connection or a fuse or am i right with the ecu?

rian Posted February 14, 2013 Report Share Posted February 14, 2013 It sounds like your alternator is the problem, you can get it tested at just bout any auto store. Quote Link to comment Share on other sites More sharing options...
Tazrolla Posted February 14, 2013 Author Report Share Posted February 14, 2013 i can put the multimeter on it but i don't think that would be the prob as the good batt that i put in there was outa my every day driver with hi cca batt outa a volvo 760 ... And.that batt has no probs turning over a v6 (taken straight out of volvo and into rolla and wont turn it over... I have thought might he starter but the fact that the starting prob started at same time as tacho and running issuses started at same time Quote Link to comment Share on other sites More sharing options...
Tazrolla Posted February 14, 2013 Author Report Share Posted February 14, 2013 I sould also note that the old rolla batt was farked long before the ned engine went in as i used to use it for the electric motor on my boat when the rolla was off road with old farked engine in it( bout 6-8months) the rolla didnt killed old batt... I did;) Quote Link to comment Share on other sites More sharing options...
