Hi there I've just built myself a Control box/Pod/Ula tester . It tests the Ula for voltage drop and also puts a load on the Ula to see if the power side (left side) is working correctly .If you want I can test it for you. For a small charge . There would also be a charge if the pod needs repairing .That is if it is reparable ..Just send the pod and the return postage .It can also be used to test the pod /the control box /and also the wiring harness. If the ULA is damaged it cannot be repaired ....I do have some spare ones with different fault's on them for sale but not at the moment ...Keep looking on the site . Photo's to follow ...
