JLG 40 will only go forward and not reverse

[franput]

I have old an old JLG 40 foot 2 wheel drive that will only travel one direction. I opened up the control
in lift. The variable potentiometer seems to be bad. Does any one know where I can buy one?

Welcome to HEF franput. :drinkup

Depending on what machine you have, and you in fact determine it's only the potentiometer is bad, it's likely you can obtain a pot from Hindley Electronics.

We also have a two wheel drive jlg 40 h lift that only moves forward, although it is a mid 80s model that is all hydraulic... any ideas for us?
