		Seems odd if that's the case, never heard of that before, don't really know much about the electrics though. 
The voltage when the glowplugs come on shouldn't be there i don't think, injectors receive a firing signal of 80v and not much else afaik. Should think it's interference/feedback from somewhere else, did you check to make sure all the earths are intact?
