Battery Negative Lead
« on: March 23, 2014, 12:14:00 am »
I pulled out my battery drawer to check the fluid levels before leaving on our shakedown trip in our 2350.  As I was hooked to shore power I never noticed a problem.  When unplugged shore power I found I had no battery (DC) power or control at the switch by the door.  Batteries had six volts in each one but nothing on the coach.  Called PC and spoke to Bobby and he said on back wall behind the batteries there are two in line fuses and a dc circuit breaker that will show a red flag when tripped.  When I crawled under to check these items, which were all good, I noticed a large black wire hanging loose.  Closer look indicated a wire end connection with a broken off bolt in it.  Closer look indicated where it had been screwed into the Ford frame and broke off.  Apparently when I pulled out the battery drawer it snapped off this bolt in the frame.  Bolt had to have been 3/16's, so to break that easily it must have been overtorqued.  Sanded the frame, installed new nut and bolt and all is back to normal. 
     Lesson learned could be helpful to other owners.

Thanks for the information Bob.
I wonder if my 12v batteries have the same fuses and breaker?
I guess I have another project, to check this out.

Tom,
The 6 volt batteries are connected to each other in series, providing 12 volts to the chassis.
The 12 volt batteries are connected to each other in parallel, providing 12 volts to the chassis.
Consequently, the breakers and fuses should be the same.
Carry on, regardless..................

I knew that. What I didn't know was about the fuses and breaker. I just checked my PC and I do have them. Is that what they call "Extra value"?  ;)
