We have a 5 Sieries Toyota Electric truck. Shop guy drove it up the back of a Tilt Deck Truck. Quite a steep incline. Did it twice. Now the truck accelerates in a jerky fashion. Either the Rotary Sensor or the Drive Motor is burnt. What is your thought about the steep incline causing the problem ?
+VideosByAl 5 series toyota are dc motors I don't think it has encoders. Couple of possibilities, I would check travel pot signal to see if there are drop outs on the signal, loose connection on motors or contactor. Worse case scenario is damage in the drive unit. Steep incline would put a lot of stress on the drive unit for sure but hard to say if it caused the problem.
+ForkliftGeek The Travle Pot does have some drop out. Being the Pot is a wear item, the shop guy must have finished it off. Regular price for the field repair is $403, but they offered to do it for $213. Seems reasonable, if it fixes the problem. We just spent $4500 last year to have the Drive Motor Turned, so there is some concern yet. Thanks for input.
Michel Dupras when I poked the test light to the horn terminal I was not pressing the horn switch. I was giving the horn a negative from battery. The horn switch switch is supposed to give a negative to the horn.
Ohh ok I thought it had to be pressed, that makes sense now. Thank you for your videos, I watched all of them, as a beginner in the field, it helps me a lot!
Hello, I’m dealing with a electrical battery forklift model 8fbchu25. Both my Horn buttons went out. When I press on the steering wheel horn it makes no noise. But when I press on the rear handle horn button it makes a “click” sound. I’m thinking it’s a contractor or relay making that click, but no horn sounds. Any advise would help, I’m new at this forklift stuff.
If it does not work with both the front and back switches it's more likely the horn or the fuse. Test at the horn itself if you are getting battery voltage and negative.
