Crown SP3020-30:
code 48

So I came in the other day to one of my stock pickers immediately reading a code 48. You key it on, let it run through its test, you depress the deadman pedal, and as soon as you try a forward or reverse action on the hand throttle it wrenches out and throws up a code 48.

I went as far as replacing the 3REC, all snubbers, and capacitor bank. still had the same issue. I even called in tech with Crown. he was here for a day and a half. he came to the conclusion that it was the distribution board. so before I went to order one I swapped it with one of my other trucks. the problem did not follow the board. it stayed with the truck.

So I am wanting to see if anyone has any ideas.

Ok so after several hours of troubleshooting and not finding anything. I finally just pulled one of my other lifts off the floor and started swapping parts. I pulled the entire transistor block i.e. capacitor bank, 3REC, 4REC, SNUBBERS ETC,.

After swapping them the problem followed the transistor. But now I've got the same problem but with the lift I put the troubled transistor in. And now im getting a code 46 instead of 48.

Ive swapped 3 rec and 4 rec and snubbers. tested capacitor bank and MOSFET. I had some odd readings on the MOSFET.

Does anyone know the proper resistance reading on this?

Code 48 could be direction contactors check tips and internal parts for binding, fed, rev switch along with accel pot, that the pot reads correct at ev100 when switch is engaged

What voltage do you have at T2? Did you make sure your contactors were working correctly. Lastly triple check your pins at the connectors on the EV-100 control card. If one of the female pins is spread or not seated well you get this code.
