Hi,
I have and Arosa (Lupo) 1.7SDI which I am considering making alternatorless.
As part of this I'm obviously trying to reduce electrical power usage as much as possible before I start.
There is a shut off solenoid in the injection pump which is normally closed. When the ignition is powered on, it's coil is energised opening the solenoid. Once the ignition is switched off it springs back and cuts off the diesel flow killing the engine.
The problem is that it draws 2A just keeping itself open which adds a significant amount of electrical load - especially in summer when there are almost no other loads without lights etc running.

Options would seem to be to remove it's plunger and remove it's wire so that it's always open and perhaps install a normally open solenoid on the fuel line just before the injection pump.
Was just concerned that there might be issues with cutting off the fuel flow before the pump instead of at the existing shut off solenoid location?

I'd value any opinion on the matter.
