Z1000H ECU Circuit Diagram

#1 PostAuthor: cheeme » Tue Apr 02, 2013 6:41 pm

It seems that my ECU is draining a fully charged battery over a 24hr period.

Would anyone have a circuit diagram or any thoughts...Ive opened up the ECU and there is nothing obvious like a blackened component.

Thanks.
Shaun.

silly question but are you sure its the ECU.

Does it notdrain if you unplug the ECU ?

Just a thought......

Chris, Ive had the ECU disconnected for the last 24hrs and the battery has maintained charge. With it connected the battery drains flat within 24hrs.

Oh dear.

might be worth ringing these guys to see if they can help. I know the previous owner of my H had the ECU checked but unfortunately I don't know by who.

After a bit of digging Ive found that the EFI system is a Bosch L-JETRONIC system. It was used on lots of cars from Alfa Romeo to Porsche to VW.

A couple of potentially useful links..
