Wiring diagram for 2008 Bambi 19'?

[zagarino]

After a year's work I'm finally taking off from Hood River, OR tomorrow and going south along the coast. One last (ha!) problem. Tongue jack motor only lowers and won't reverse to raise. I know I missed something during the rebuild. Any help on wiring schematic or suggestions would be greatly appreciated.

BTW, strip and polish completed in 250 hours. Yes, I am stupid in love.

The problem is in the electric jack. There is only a 12 volt line to the unit and it is grounded to the chassis of the trailer. Since it lowers, the unit is getting power. It could be a limit switch or raise/lower switch.

From your picture I see you had the motor off the post make sure the set screws are tight as that is the path to ground and a poor ground may not carry the power used while lifting the trailer.

Since the jack is moving in at least one direction I would assume it is not the limit switch. Open the top of the jack and test the connections on the reversing switch.

You should find 6 terminals. The center terminals are 12 volts and ground. The 4 outer terminals should be crossed at the switch and 1 wire each, total of 2, going to the motor from each end of the switch.

This way power and ground are switch when the switch is moved in either directions off center thus reversing the direction of the motor.

If the wiring checks out then the switch itself is most likely bad inside.

I had the same problem with my 2009 19' CCD International (I hate the name "bambi'). Sometime it would work, not work, work one way only. Problem caused by sitting out in Seattle rain all year. Ordered new switch from Barker Mfg, part no. 736-0010 $14.05. It arrived and I am going to put it in soon. From now on I will cover the jack head when AS is stored.

I forgot to mention that I bought my AS new from Sutton RV and it came with a stack of component brochures and instructions including for the electric jack. I can't find their web address at the moment but you can either do a Google search for Barker Mfg or call them at 269-965-2371. Have your jack model number ready when you call them. Or I can send you a copy of the wiring diagram if you want.

We use a large boat bumper (with one end cut off) and bungee cord to cover our jack head and protect it from road debris and weather. This keeps out water, dust, flying rocks, etc., and shields the jack head from the sun (a real problem in Arizona); and our five year old Atwood electric tongue jack still looks brand new.

Thanks all. It's the switch. Looks like I'll be hand cranking this trip.

Before you get the crank out try just working the switch several times. It is more than likely just dirty contacts and you may be able to clear them.

That is a common switch so if you can't find one locally call the jack company and have one sent out.
