I can try a repair. They are not normally repairable. A rebuild replaces all internals. If I cannot repair I can supply a new charger with your cables for $300. ---

Bad connection or no power on green wire. Check for 72v on green when red is connected to Gem +72 Bolt battery. ---

@Inwo there’s this random green cable from the charger that isn’t connected to anything. Is this the problem? ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/e/e9fafd07d806d65745848a7811f46a1f99195775.jpeg) ---

No, but check for voltage. It should have 72v unless it has been shorted, which damages charger. ---

Open circuit between red and green is an internal charger problem. Possible relay that connects the interlock wires. Grn & red. ---
