Alternator  for BMW versions /6 and /7 
(base diameter 107mm check!)

our complete generator/ignition system see here: 71 67 999 00

Magnet based single phase alternator. Output 12V/190W DC. No carbons, hence maintenance free. Replaces the original 12V Bosch 3-phase alternator including rectifier and regulator. There is no need for changes on engine casing.

for the /5 and early /6 see system 70 67 499 00

Note: Does not replace ignition, this is alternator only.


Picture to left shows complete system (with ignition module)

Please observe!
  • does not support any existing electronic revolution counter if it is connected to the stock generator.
  • the security switch (which prevents electric starting when the engine is running) could be used if the red/green wire of the new regulator is connected as shown here:
  • has only 190watts (ignition power however additional to that) and offers therefore less electric power than original alternator
advantage over original system
  • all parts are new
  • no more wear on carbons and collector
  • no more trouble with damaged rectifiers
