Hi,I say don't bother going to the industrial area for that,try to go to Bin Mahmoud street and look for Alsamaa auto electrician shop as this shop is having almost all good used electrical parts-dynamos,compressors ect - In case that you don't know the way go strait from Ramada signal to the Jaidah fly over, then make a U turn from under the Jaidah fly over,drive slowly as there should be a small and short street sign on the first right turn which says Bin Mahmoud,this is it turn right,drive strait till you find a traffic signal,turn left from it.Stick to the right side as Alsamaa garge should be the third one if I am not wrong.Good luck.
