dasatcopthorne Posted March 28, 2017 Share Posted March 28, 2017 Hi Guys. Can anyone help at all with this problem as I don't know enough about electronics. Here's the problem. After a wiring mess up I have a very low output from this controller. It should be around 12/13 v dc but is only a max of 2.14v dc I have opened to controller and looked at the PCB. No signs of overheating. The input is 21V ac and has never given a problem before. I have checked the Bridge Rectifier and this produces 17v dc but at the output solder points on the PCB it is only a max of 2.17v dc. The only component I can think of is the thyristor. Could this be damaged? Is the low max output a sign that this comonent is damaged? The trouble is I don't know how to take measurements from a thyristor. I can read the number on it, TIC106D, and these seem to be available from RS Comp. Any help much appreciated. I don't have a circuit diagram!

cliff park Posted March 28, 2017 Share Posted March 28, 2017 What make and model is the controller? By 'wiring mess up' do you think it is likely the output was short circuited ? Link to post Share on other sites More sharing options...

ejstubbs Posted March 28, 2017 Share Posted March 28, 2017 My guess is that it's a predictive text/auto correct typo for AC. Link to post Share on other sites More sharing options...
