Hi.
New member here.
We've been having issues recently with one of our Yale 10000lb 36 volt forklifts. As soon as we engage the hydraulics to lift, tilt or side shift, the travel motor loses power and slows the machine down to a crawl until we stop using the hydraulics. It has plenty of speed until we engage the hydraulic motor to operate the forks.
It's not the battery as we recently put a new one in.
