I think the display should still light up even if line contactor has failed to energise.

Check pos supply to key, sounds like you have lost a feed somewhere.

Fuses broken, no start lift truck. I´m sure.  Example, working lamp rear broken. fuse broken, lift truck no start. Because lamp is cortocircuit.



PD.- Sorry with my english, only speak spanish.

Hi ,

i have weeks ago a truck with bad contacttips on the right side, no steering no fan and lights etc.

I replace the two contactors for new closed contactors and problem solved.

Thanks to all of you for your tips!
The 2 fuses(15A) near the accelerator are ok,the contactors to. The problem is that theres no current signal from the logic card in Main controller to the main contactor(wires ok,with continuity).

I think our friend electrodrive may be right,its strange the display didnt turned on,ill keep trying !
