“The WS500 was accidentally connected without the required Victron crossover cable while the engine and Cerbo were powered. A VE.Can terminator melted. Since replacing the terminator, the WS500 reports ‘Lost Bus Connection’, remains in Standalone, and no longer reports Field %.” ---

If you have the correct one in place and that is still the error, chances are the voltage that was there where it should never have been has had more than the terminator as a casualty. ---

That’s what I’m thinking. And it’s not going to be cheap ---

> [@Dkirk](#): > > That’s what I’m thinking. And it’s not going to be cheap No. My heart dropped reading the post. Hopefully its not an RIP for 3 devices. Check the port speed is at 250kbps Hopefully the terminator took the brunt of it. The wakespeed probably took some of it too Does the fogstar bms report to the cerbo ok? The wakspeed might just need a repair or replacement board. ---

I do have another Cerbo. But it’s a mk 1. It does see the battery on 500kbps. It sort of sees the Wakespeed on 250 on the other can. But no field data. And stuck in standalone. And no charge. No error lights though ---

Ah. That is both good and bad news. Then the wakespped transmit board is probably fried. Their support should be able to tell you more. ---

Oh well. It’s only money. I wanted the Bluetooth one anyway​😑 ---

By the way. The melted end was the cerbo end. Would that still ruin the wakespeed ---

could do, but there is also the possibility of repairing the wakespeed… Possibly only the can Interface chip fried? ---

This is what i was thinking. Might not be the whole unit just the comms bit.
