I have a 1985 TM 17 36 volt, I need to order a new control card but to do this I need the serial number. The problem is someone at some point took the I.D. tag off the lift. Where else can I find the serial number on this unit. Also, the control card is a GE IC3645LXCD1 VK (or so it says on the card) I need the EV100-LXT, I have located a LX but not the LXT. Can anyone help point me in the right direction on this, thanks in advance.
