Customer Question
Having a power issue...

Having a power issue. no 12v to coach when unplugged from shore power.

Mechanic's Assistant: What's the make/model/year of your RV?

2004 jaycon greyhawk,ford e450 chassis. battery is charged (13.5 volts) power to all wires leading from battery. battery disconnect solenoid appears ok (power from both sides). wiring diagram shows power from this solenoid running into coach and spliting and an insolator to inverter and load center yet power is gone at this point...

Mechanic's Assistant: Is the power loss consistent, or does it fluctuate?

Consistant when off shore power, when plugged in everything works fine

Mechanic's Assistant: Are you fixing your E150 yourself? What have you tried so far?

Tested all wires from battery, tested contact points on isolator solenoid, all appear good. tried to jump solenoid contacts to bypass just in case...no luck double checked neg batt cable and ground. tested all the same for working condition when plugged in just for good measure. checked solenoid for chassis battery seems ok...

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Coach is sold and new owner is supposed to pick up tomorrow so im a little desperate at this point

My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.My info is somewhat limited on your model here but I had seen no one else has responded and would like to see if I can help here.If at any time you feel that I cannot help with this please let me know.

This may be due to an internal electrical fault in the power inverter itself.If the inverter has an internal electrical issue it can cause a fault like this here and would need replaced.I would have this tested as well as wiring running to it for any issues needing repaired or replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
