e30m42 electrical problems with charging/current consumption
Posted: Sun Feb 21, 2016 5:34 pm
hello, i need some help with my e30. i swapped 4 moths ago an m42 from e36 in my e30 m10 and everything is ok, except that i have 2 problems:
1. i have a current consumption of 0,18 A even if i disconnect everything( all fuses and relays removed, no alarm, no central locking, no radio, nothing) and i can't figure what can discharge my battery (my battery is new). what can be?
2. if i pass 3500 rpm, the light for battery in the dashboard get on. i have changed the alternator, everything was ok for 3 days, after that, light come on again. i changed the voltage regulator and put a new one, everything was ok for another 3 days, now my charging is again 13.8v instead 14.2-14.4v and the light come on again on the dashboard after 3500 rpm. what is destroying my voltage regulator?
i am out of ideas and i can't find a way to solve this 2 problems so any idea is good.
