Hello, I have an older model Clark EC25-SSC electric forklift. I keep the battery charged. It does not get that much use...maybe a couple of times a week 1-2 hr use..so it does stand a good bit. This past week it discontinued to engage forward. Reverse still works fine. All other movements work fine. With seat down and forward lever in position I push down the acceleration pedal. Contacts engage but no forward movement or sound. If I hold the pedal down all the way the second speed contact engages but STILL no movement forward. Thanks in advance for any help or replies.
