Having problems with low volts on the sub-main circuts when plugged into 30amp shore power. All electrical outlets and microwave when tested show 24 to 85 volts. All circuts on main circuts show 124 volts, this includes air conditioner, refig, washing machine etc.
When plugged into 50amp shore power both the main and sub-main circuts have 124 volts. Also the sub-main circuts run off the inverter/charger breaker on the main.
Any ideas????

The adapter that you are useing is probally only powering one leg, which happens to be the one that the a/c is on. I havn't seen one of these adapters to tell how its set up, but if it has worked before on other 30 amp shore power receptacles, then the adapter is probally defective. The 30 amp receptacle is 120 volt only, where the 50 amp if properly wired is 120/240 volt. Everything in the MH is 120 volt and is split between two hot legs on the 50 amp receptacle. Without a jumper in the adapter, only one leg to the MH is powered. Since you are getting up to 85 volts on the other leg, the adapter is defective.(loose or burnt connection)

I agree with Hillbilly2. Go out and purchase a new 30 to 50A adapter. I bet it fixes your problems.

I had the common black dog bone adapter, but THIS ONE is much better.

It's a bit more expensive than the black dog bone, but comparing them side by side, the yellow one just seems to be a better product.

There's definitely a difference in the quality of the pins on the plug.

The Camco has very heavy duty thick brass pins while the black adapters are made of thinner folded brass. This is important to help dissipate the heat away from the contact point and keep the voltage drop to a minimum.

A lot of the 30 amp sockets in the campgrounds are well worn and have been over heated so that the outlet spring tension is much less. So what you have is a problem that compounds itself to the point of a melt down of your plug. The Camco is going to deliver more power with less heat at the plug.

Here is a lot more discussion about how OxGuard can help improve the contact points.

Tried severalnew adapters and they did not solve the problem.After talking to Winnebago and the manufacturer of the Inverter/Charger Combi it sounds like the the charger porition of the system has a problem. I'm taking it to a certified dealer to have the Inverter/Charger tested.
Thanks for the imput and I'll post the results in early April.
