looking for wire schematic for a 2003 Keystone big sky
JA: Have you checked the vehicle's manual?
Customer: yes not one in there
JA: Anything else you want the mechanic to know before I connect you?
Customer: no

Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

Unfortunately, Keystone says they have none available and that pretty much sucks. I have an RV shop and have wished many times I had some available. If you can tell me what the problem is, I may be able to direct you in the right area or help with some testing. All follow ups are included in or fee.

Ok, what info do you need?
tripping main breaker at shore line when plugged in.
Details have been fade so bad on in side fuse panel of coach I can not read what the breakers control and power does not stay on long enough for me to isolate
I have two breakers that I can switch off and the problem goes away but I cant read whet they control?

Many times the problem is the water heater. When the element shorts out it can trip the breaker. What else isn't working when you switch those off?

most of the living area and AC

Turn the A/C off. What about the water heater? And are you using any kind of adapter on the shore cord?

I had the hot water heater working, with the breakers switched off?
was plugged into 50 amp
and also tried my dog bone to use the 30 amp

Do you have the 50 amp available? If so, use that. The water heater will work on LP mode with the breakers off, but not on AC mode.
