Rear shock ESA preload stuck in MAX .. while doing general 6.month maint I usually cycle rear preload from min to max. Unfortunately today it decided to stay in max and won't return . Have tried cycling through max/min/auto many times. Turned the bike of for 1 hour and back on and then disconnected the battery and reconnected with no joy. I have read on some internet posts that you can force the actuator using direct 12v to shock via connector plug. Anyone had this issue and tried the force power route ?? Bike is 2022 with 36,000 miles on it . Any help would be appreciated before I start using main stealership or replacement shock .. thx in advance
 
Given the mileage I suspect your shock has wear/corrosion of some sort that you can’t see externally and is causing stiction . If the current drawn by the motor exceeds a threshold the power is cut to protect the circuit. The 12v trick might work but I suspect only for a short period. As said get Denzo to service it for a fraction of the cost of a replacement.
 
Has the push rod from the level sensor become disconnected? Mine disconnected itself on the very first time I rode my 1250 GSA and was stuck in max.

Tbh I only ride in MIN position , so if I can get it back to MIN I will live with it. Question is are the 12v trick wires easy to identify .??
 
You would need to consult the circuit diagram to find which wires are 12v and ground or it might be online somewhere. At 36k the damping is probably past its best as well. My front shock dropped its load at just over 20k so I had both done. You don’t appreciate how much damping has gone because it’s a progressive drop until they are rebuilt.
 
Stupid q. Are you sitting on the bike? Might be worth trying on centre stand if not already done. JJH

Thx JJ , yeah bike is on centre stand , so no real load with bike running .. 😔
 
Direct some silicone spray around the preload assembly etc and leave for a bit. It might free things off enough to prevent over current
