I have a pro rider trolley which is less than a year old but I cant find the receipt. The trolley loses all power, nothing on the display.12 volt DC power is present at the S1G controller PCB. I line checked the cable between S1G and display D-64186 which is OK. When it does power up, the power up relay clicks and energises and all is OK, then sometimes it won’t power up, relay does not click and there are no lights on the display. If I buy both units from your website will this fix this fault ? Is this a common fault.
It is difficult to say where the fault lies. First it sounds to me like a connection fault. I would start to check the power supply connections for damage; the 3 pin battery connector lead. Rather than any component at fault, I would go over all the connectors, check for loose connections, give them a clean and also a spray with some WD40. Only after that I would start to look at damaged components.
