I have been having a lot of trouble keeping my electrical connection in the 7-pin connectors for attachments on Toolcat booms, mainly when using snowblowers and snow v-plows. Even when new, always after about one year the connection becomes weak and will cause an error code 50-56 that either turns off the auxiliary hydraulics or stops the machine abruptly. I have tried cleaning the connection with electrical contact cleaners, using a tiny dental floss brush to clean the holes, and still cannot get these connectors to last. The only solution I have found so far is to replace the 7-pin connector, but that involves buying a complete new wiring harness for the Toolcat and/or snowblower or V-plow at around $150 each. Than the connector works fine for a year and the same problem shows up again. Does anyone know of a solution to keep the connector functioning or something to keep the contacts from corroding?
