Electric forklift charger problems

[cornish wood burner]

Still not worked this out. Checked the socket - Good. Checked the continuity of all the wires in the charger - Good, nothing 'seems' out of place. Checked all the fuses - Good. Checked the forklift batteries which are reading 38.9V. As a 40V system obviously they are low but this makes sense as I was trying to put it on charge due to the forklift becoming sluggish.

 

Would the charger not work if the battery voltage is too low?

 

When you say you have checked the socket and charger wires is that positive and negative. A break in the negative line will have the same effect. If you have nothing with a 30 A plug you could use the lead/plug from your charger to power something else to check the cable and socket. Take the lead and wire a trailing socket on to it would be an easy check.
