Hey guys I’m new to the forum and to the f4i platform and have a weird issue with my 2002 f4i. The other day it developed an issue where it will not crank over unless if the rear brake is pressed. I’ve looked over the wiring and don’t see any loose/bad grounds etc and don’t see anything concerning. Has anyone else had a similar issue? I’ve noticed the that the left side of the tail light stopped working as well. Tip has been bypassed up by the front (no headlight method it’s a street fighter and has a light bar as headlight and is not tied into factory wiring.) I’ve also looked at diagrams for the tail light wiring and everything is wired correctly as far as that goes. I’m not an expert on wiring by any means so any advice would be appreciated!

 

Alright guys finally had time to dig into it. The problem the whole time was 2 tabs in the kill switch plugin got bent and were making a bad ground!

 

Glad you've sorted it.

With it being completely non-standard wiring in that area it would have been almost impossible to diagnose it sight unseen.
