So i recently aquired a 1991 melex 412. In great condition for what it is. Batteries will need replacing sooner than later but i just drive it around my neighborhood. Anyways my question, there is a toggle switch right to the left of the forward/reverse handle and also near the charging port. I was told when i bought it that it was for tow mode but he didnt know which way is which. I called a local repair shop and they told me there is now way it is a tow switch because something that old didnt have tow mode. Ive tried driving it for a short period of time in both up and down on the switch and cant tell a difference of it doing anything and without trailering it in and getting a bill for them to tell me what it does, i thought id try here. Thanks a bunch. I will attach pic of it from the outside. And another one from the inside tomorrow.
