I just fried my Cycle Analyst .. can I still safe it?

Hi Everybody,

this is not my day

I have the following setup:
2 Cycle Analyst
one runing a C9 2707FD Front Drive Moter with Phaserunner
the other runing a BBSHD Mid Drive Moter with Phaserunner

I changed one Cycle Analyst to run 5v PAS for the BBSHD PAS Sensor the other I left stock (10V). Big mistake, should have changed both!

Both Cycle Analyst are connected to the PAS Sensor of the BBSHD with one cable not having the V+ Line.

Now I just pluged the wrong Cycle Analyst (10v) to the PAS Sensor (5V) of the BBSHD and the Cycle Analyst went dead right away!

I checked with the still working Cycle Analyst the PAS Sensor and that one is dead too.

Opened up the dead Cycle Analyst and it looks ok.

Any Idea how I can fix it?

Cheers,
Christian

Depends on what died. If it's just the high-voltage-to-low-voltage converter, you can bypass it by putting 12v to the low-voltage input pad on the CA board inside. (I don't recall which pad but the CA manual or ebikes.ca site should list it).

If you can't fix it you can call up Grin for an RMA to have them repair it.
