Hi Everyone,

New relay card arrived. Looks a whole lot better than the old one!

Relay K4 is always latched regardless of the key position. As soon as the battery is connected you'll get error FN. As in the VM is always on.

With Relay K4 plugged in and the key turned to 'on' no other relay will latch and the usual 5J 5G error comes up.

Unplug relay K4... Turn the key to on, all other 3 relays latch and the truck starts up fine. Has drive, lift, steer all good. It does have an error 61 comming up.
It did have an error 8L however after a few minutes use it has disappeared and hasn't came back.
Stepping on the deadman the brake on the top of the drive motor clicks and all is good. About 20 seconds of being on the deadman the brake will start clicking on and off non-stop, just click click click...

Jumping the pins on the relay K4 socket and that brake click click click issue is gone. (error 61 is still there). However I can't leave the relay jumped as when they key is turned off, it goes back to the 'FN' error.

I'm assuming something is wrong with the cirucit for the K4 relay coil. As with that relay plugged in, no other relay can start.

Checked the VM for burned pins, all looks o.k.

Everything else seems to be all working! Any ideas?

Many thanks!
