Q: 84 Motor home won't turn over. There are battery power supply issues.

asked by on March 04, 2017

We just purchased a Georgie Boy Excalibur motor home, 464 Chevy engine. Died down the street from my house. When trying to start engine only clicks like a dead battery and I was able to jump it and park it. This was three days ago. Now the motor home will not even turn over at all (no engaging of anything no activity) unless its plugged into the house and then it acts like a dead battery. Replaced the battery. Now when the key is in the ignition and only supplying electricity a terrible clicking noise (not from attempting to start) occurs out of this small part (unknown) with three wires attached to it. When I apply the brakes it stops, if I do not apply the brakes then the clicking starts up again. Also the engine won't attempt turn over unless I DO NOT have brakes on. If brakes applied engine is cold and does not even attempt to turn over. It will not jump start anymore either. If anyone can help diagnose it would be appreciated!
