Thanks for all the responses. At the moment there is no electric tongue jack installed, we removed the Atwood unit the Nash came with. The motor turns but no movement from the ram. We took it apart, a bearing boss for one of the shaft ends in the plastic gearbox failed, poor material/design in our opinion. The similar unit on our 2003 AF worked flawlessly for 20 years, still going. Its a shame really - the motor, switches, cover, bevel gears, etc. are all like new. Hate to scrap it but we have an American made Barker on the way. If anyone wants the Atwood for spare parts you can have it, we are 90 minutes south of Portland, OR. There was a single lead with an eye terminal from it to the positive battery terminal with the other connections, that is only thing we've removed so far. Everything else is unchanged as we bought it from the original owner, an older gentleman. He is beyond assisting with this.
Thanks enblethen, responses:
30-amp fuse could be for the electric tongue jack.
> No jack/wiring installed at this time.
Number 4-gauge wire should be power to the 12-volt distribution panel.
> Agreed, we need to find this panel.
Should be a number 10 wire going to the umbilical cord to tow vehicle.
> If it is, the connection must be made inside, we'll look.
Number 8 wire could be for the solar panel controller.
> We think so too, need to figure how to test for it without damaging the controller.
Should be another small wire 10-12 for the break-away switch. Battery disconnect should not disconnect break-away switch!
> The only direct connection to the tow vehicle is the standard 7 pin plug and cable. Taped to it, where it comes out of the body of the trailer are a pair of black small gauge leads, look to be 14ga. These connect to the breakaway switch. There is no visible connection of this switch to the batteries, if it is it's done inside. We understand the safety comment made about not having these on a battery disconnect switch.
We're reluctant to pull wires on/off the battery when circuits are hot, guess we better invest in a clamp-on current meter. We'll do some homework and get back to the forum. Thanks!!
