We had a lift come in this week that had been sitting for a few years idle. The battery needed water and a good charge. This truck only has 14 total hours and is in as new shape (looks like it just came off the showroom floor). We hit the battery hard and got the gravity to come up to a good level and a voltage of 25.7 volts. We plugged it in to the truck and had 4 out of 5 green LEDs but had no functions out of the truck, not even the horn. Both fuses were checked and both are good. We tried a larger good battery from an order picker @ 26.8 volts with the same results, also checked to make sure the break bypass was not hooked up. The motor controller is not like the Curtis controllers that I have seen before with the motor cables coming out the bottom of the controller, they come out from what would be the top that faces out of the lift with no LED or handset jack that I have found. Any help would be greatly appreciated. Sorry I do not have the serial number with me but will try to post it here when I get back to the shop tomorrow
