Trigger Point Conumdrum

Hi
Sorry meant where are the components for each pin ( 1 and 18 ) so I can investigate further?
Regards
Peter

Hi Peter,

well 1 is the air temp sensor on the air filter housing. 18 comes from starter.

Oh I had the air temp disconnected because I had the air filter off - I’ll have to check that one again (just checked and it is 427 Ohms @ 11 degrees C - At specs ). So having this disconnected could impact it starting?

Pin 18 - Do I need to check this between Pin 18 and Pin 50? (if so where is PIN 50?)
Thanks
Peter

Hi Peter,

I do not know what you talk of pin 50. pinout is here jetronic.org/en/d-jetronic/pinout#mb8

Hi,
In the connection column of #18 on the 'check-list' it states - start signal (to pin 50).. There is not much information on exactly what the start signal and associated components do? So I was wondering how to check this further?
Regards
Peter

Hi Peter,

well pin 50 is the German standard number for the starter. It has nothing to do with D-Jetronic. This pin 50 on starter is connected to pin 18 of D-Jetronic ECU. Measure against ground pin 11. While cranking engine it should show +10-12 V.
