Yep, lots of ideas...

Does that unit have the led display?
If so, what code?


If not, does the p/s motor turn on?
If no, check seat switch/brake switch.

If yes check the switch on the accel pedal.
Does it click, what's the voltages?

If that's ok, check the drive system for any welded contacts.

The card looks for ~50% battery voltage across scr1, then it will close a direction contactor and check for 100%.

So your failure is either in the switches/wiring/fuses or you have a shorted contactor/bad motor/bad rec/bad card.


I'll need the s/n to get more specific...
