Hey guys. just signed on to this. I'm having some trouble with our Hyster 110hft s005. its throwing a 168-4 code and there is a faint beeping coming from around the fuse panel/hydraulic tank, as well as a electrical whining sound. I put a multimeter on it and it seemed to have a power fluctuation of 12,10,and 8. but when I go to start it the terminal on the dash kills off and then when I release the key it does the beeping and what not but doesn't even act like it wants to start. I'm assuming battery? let me know, thanks!
