Hi,
im working on a crown sp3500 and cant find the source of this raise switch fault. upon start up after charging (or any time battery is reconnected to lift) i get the beeping and Raise Switch prompted on the display. i have already ohmed out and checked low and high speed switches and both test good. found fault code 435 and went through the test/resets and still no luck. if i let the lift beep away on initial start up it eventually clears the code and operates normally, even when keyed off and on again. i only have this issue when reconnecting the battery. Has anyone else experienced this issue, or maybe know what steps to take to repair? i have already gone through all of the service manual steps for trouble shooting code 435 with no success.
Thanks Blake
