I recently bought a used rc3020-30 and noticed some possible issues. This is the first electric Crown i've owned so i'm not sure how major/minor these issues are.
First, when initially taking off foward or reverse it will shake pretty bad for an instant but then drive fine once it gets going.
Second, I have noticed that when turning/pivoting from a stalled position it will just cutoff randomly. The forklift will stay on and I can use the hydraulics to move the forks as normal but it wont drive. I have to switch the key on and off and it will run again.
Third, the battery status meter only marks half way even after i've left it for a full charge.
I'm thinking that these issues all may be tied to a faulty battery pack but i'm really not sure. I know I will probably need to give more information but if someone can toss a few ideas that would help.
