I have an ’05 Electra glide and the cruise control will not activate. It passes test for front & rear brake switches, the roll back switch, set & resume button and it will do the cable lash initialization (motor will slightly accelerate and then return to idle. When doing the diagnostic trouble shooting for ‘Cruise wont engage’ listed in the service manual. It passes all test except the one where you turn rear wheel and cruise light will flash, but doesn’t. Following further thru diagnostics, it states to unplug cruise module and check “K” terminal (manual labels it the speed sensor)with ohms meter. There is no voltage (which is correct) but it does test with a ground on that terminal(it should test clear or open, infinity). Manual says to check wire for ground. This is section 7.12 in manual.

I pulled the tank and outer fairing, & side panels looking for something obvious. I even cut back a little on wiring harness but could not find anything.

What really confuses me, I can unplug the main harness from the interconnect harness that feeds the ESM and the ground goes away. But checking in both directions on the wire(its w/gn) it test clear in both directions. This connector is located behind the right side panel.

I have removed the speed sensor, cleaned it (actually it looked fine, no metal shavings) and the speedometer works fine.

Short of ripping open the entire wiring harness or replacing the speed sensor ($65, non returnable) I don’t know what to do. I wouldn’t be opposed to opening up more on harness if I new which direction to chase. It totally baffles me how the ground can just “go away” when I unplug that connector.

Can anyone give any advice how to pursue further?

Both working properly

Vernal, wow! First off let me thank you for taking the time ti look at wiring diagram and trying to understand my problem.

at 17 A i disconnect cruise module. The k terminal on the harness test with a ground on it. When i disconnect connectors 8A & 8B the ground goes away at all points. 17B connector at K terminal test s clear. At both 8A & 8B connectors the w/gn terminal test clear, no ground. Plug it back up, ground reappears at reappears at 17B on K terminal.

Followed your instructions. The short between w/gn & bk goes away when i unplug the ECM (its fuel injected. Does that mean the ecm is bad?

Thanks, but i have already tried those except the one where the bike is running. Mine wont engage so that test wont work for me. Maybe i can find a cheap ecm and determine if that is issue. If i had any hair i would pull it out.
