I've resently ran across a Yale pallet jack at a Walmart with the al 10 code and what I found was a bad connection at the motor causing the code, there was green corosion in one of the terminals causing the code I cleaned the connector and the problem went away suggested to the customer to replace the motor harness to fix permanently.
Youn can try to downlload the actual ZAPI manual from their website if you know the model of the controller. The manual will tell you the alarm codes. Most of the truck manufacturers will follow the circuit of the ZAPI controller.
Hope this help/
does this unit have a zapi controller? does the unit move, when pushed by hand, with the battery plugged in, (brakes release with battery power)?
There is a 2 wire molex connector, as part of the harness near the motor and controller, that allows the electrical brake to power up (release) when it is connected, so the unit can be pushed or moved even if the motor or controller is bad. if this connector is connected, I think these are the codes you get when you attempt to drive it normally.
sorry i do not have one on this exact model
maybe someone else here can help you out though :o)
Swoop, do you have a manual on this unit
Hey swoop, no worries my friend. What are the fixes to these codes?
sorry for the confusing statement i made, i didnt mean that it was making any sound
Alarm codes generally mean it is a circuit failure
there are also warning codes that are function faults like trying to operate a function out of sequence.
But the explanation of what those codes are is what i posted earlier :o)
zapi and sauer danfoss usually use these code prefixes is why i said it 'sounded like it was a zapi controller'
Serial number is a b827n16037c
Hey Swoop,
The model is a mpb040-en24t2748. It wasn't making the alarm sound, it has a gauge with a display and battery meter
mpb040???? what suffix code is it? mpb040E maybe?
zapi controller? (with alarm codes such as this sounds zapi to me)
code AL02 - Brake driver KO
code AL10 - contactor closed
