      This thread has info on how to test a relay: https://www.badcaps.net/forum/showthread.php?t=71359

      Run a 12V light bulb, like a car tail light as a load on the contacts.
      An ohmmeter is not suitable to measure contact resistance, you have to put power through them.

        just assume it's for direction and jumpwire the board to test without it.

          P/N of the relay will help to locate the pinout of the relay.

            This should be the pinout for the cma4-s-c-e
            Here is a better pdf

                    Except the relay needs to be energized to change the state of the contacts, when power is removed it goes back to the N.C.contacts
                    Unlike your switch which will stay in either position, unless thats a momentary switch

                        Guys if I bought the relay and the mosfets. What else could be wrong with the board?
                        Thinking I might just buy em and stick them in??

                          everything could potentially be wrong.
                          if you power the relay, does it click?

                                  Also fyi. The trolley only moves forward. There is a pentintometer in the handle to adjust the speed.

                                    relay clicking - 50% tested.
                                    coil works - now to check the contacts.

                                    i like to open the cover and just LOOK at them - it's a lot simpler than using a meter.

                                            It's for charging golf trolley, input 100-240V50/60 Hz 1.0A output 13.8 v 3.3A.

                                            When I received the device, the device has no function. After an investigation, I found that the PWM CONTROLLER RT6575B (U6100) is getting warm and there is a short circuit at the 3V3 output. This normally supplies 3V3 for the embedded controller IT5571E-128 (U301). When measuring and analyzing with a thermal imaging camera, I found that some components are damaged: SLG4E42553VTR (U8500), IT5571E-128 (U301), LAN RTL8111H (U450), LOGIC 74LVC1G08GW (U1900), RT6575B (U6100) All these components are on...

                                            The treadmill was working fine, one day the belt snapped and after checking the unit I also noticed that the display is now showing the Controller comm error. So I opened it up and the treadmill had two boards. One is a power supply board and the other is the motor controller. I noticed there was a mouse nest, so I took power supply board out, cleaned it up, replaced the big capacitor and that did nothing. Then I took apart the motor controller and cleaned that up, and when I plugged it in, it started right up. I thought I fixed it. But when the belt arrived, I installed it and tried to power...

                                            Tankless hot water heater controller board not powering up when power is applied
                                            by sam_sam_sam
                                            I recently bought a used tankless hot water heater and the controller board is completely dead no power up when power is applied the display board works however the main controller board does not work correctly at all the fuse is good

                                            I bought a used replacement controller board that also had issues that I was able to fix and now the tankless water heater works correctly now

                                            However I would like to know if I could figure what happened to this controller board if possible

                                            Tomorrow I will take some better pictures of both side of both boards

                                            Modifing a Battery Spot Welder because of Controller Issues
                                            by sam_sam_sam
                                            I keep having the same exact issue with these battery spot welder controller boards

                                            They either do one of two things

                                            One the controller does not send the signal for the transformer fire which is a very common problem with this controllers micro controller failure

                                            Or

                                            The controller has some malfunction which means that it does not cycle the pluses more than once or none at all and should do it any where from 1 pluse to 20 pluses because you can not change the setting does not respond to its input micro controller failure

                                            This...
