Hi,

1 - Horn is not shorted

2 - Power cable through transducer loop on power card is routed ok

3 - Motor cables not shorting out

4 - Motor is not shorted, in fact it just came back from another rebuild

5 - Power Loop checked, R1/R2 (two small gold resistors on the big heatsink) I checked the resistance on with an ohmmeter and it read 2.x ohms, so I think they're good



I'm running out of ideas, almost everything has been replaced.

I hot wired the traction motor yesterday directly to battery (full 24v) to see how it runs, and it seemed to spin way too slow; figured something must be wrong internally. Sent it out for a rebuild, the commutator was apparently in bad condition/blue from overheated. Came back today, put the traction motor back in, and still code 23...


When I first got 23, Q1 was obviously the culprit (could smell it was burnt) and when the new replacement Q1 came in from Raymond, it was slightly different. It didn't have a REC2; in it's place was a wire hooked up to TP5. Maybe this is the wrong Q1...?


Yea... Advice guys?
