Crown WP3030-45:
Code 337

hi all,
I am having problems with unit cutting out with an event code of 337. Ive looked countless places on the web and found I believe every code except this one.
Can someone plese tell me what it is for and if possible how to correct it.

Inspect the chassis power cables that plug in to the battery connector.

Thanks for your reply. It is happening sporadically while moving, and lifting or lowering doesnt seem to have any affect on it at all.
Ive gone through and tightened all possible connections, but nothing seems to help the condition.
I am also getting an 857 code once in a while.

Any suggestions would be appreciated.
