Following up on our issue with the coach battery not charging while driving.
On the Grayhawk 31DS ford , there is a solenoid or relay mounted to upper edge of the firewall. After following wire back from Coach battery I found it.
Glad I did!! The terminals were very loose and the added resistance cause the
boots and insulation to melt. After tightening. the solenoid kicked in and is working.
It still will be replaced since the heat distorted the plastic cover.
I have had RVs for 40 years and every Solenoid
was made of steel!!
They can run warm.
