A friend of mine has a '18 toolcat with an older 72" SB200 snowblower on it. When it's hooked up, auger works but chute won't rotate nor will the hydraulic cylinder operate. I began by checking for 12v at the machine 7pin, which there was. The bobcat CAN bus will send a signal to the control box on the attachment and that control box converts the signal to 12v. I then checked the 4 connectors that come out of the control box (while he was pushing the appropriate buttons in the cab) and control those attachment functions - there was 12v there. So I labeled the connections and everything seemed fine. Tested it and everything was working. He called a day later and say it stopped working again. I'm assuming a bad electrical connection and will troubleshoot in the next day or so. Has anyone else checked ohms in the attachment hardness or experienced intermittent failures from the attachment control box?
