Ok, so here is the background. This unit is a 2015 (or 16) Ranger Crew 570 EFI I am working on for a friend. I will admit that electrical work is not my area of expertise, but I tend to be able to figure these types of issues out and this one has me stumped. When key is turned on, EFI Fuse blows immediately, which kills all other electronics on vehicle. I assumed first that this was a short to ground due to rubbed or exposed wire, but I have spent hours and hours investigating that possibility with no luck. I then began checking components. The starter solenoid was bad (very high resistance), and while I figured this wasn't the problem, I replaced it anyway and found that I was right. Then I began checking the actual injector. I'm not sure what all I should test but the first thing I did was check resistance and it read 11.8 on the injector. This seems low to me but I'm not sure what the spec is. Could this be the problem? And if not, what other things could I look at? Any other simple things that I could rule out?
