We have a 1999 gulfstream sunvoyer with the ford v10 I have a question.
Do the coach batteries have anything to do with starting the engine. We keep getting conflicting information. We were told that we have one bad coach battery and someone unhooked it and we we can't get the rv started again we need to move it in the next few days and we don't have the money to replace the battery yet.
Also does anyone have a diagram of how the coach batteries are hooked up so we can properly hook it back up when we get a battery.
Our friend says that the battery under the hood tests fine

We are living in the rv fulltime

Here is a description of what happened

Originally in beginning of June it was starting fine we were not living in it yet just getting ready went out the next day and it would not start we figured something got left on accidentally had it jumped by someone who had a high powered jumper. We moved into it the first part of August but only had regular house power to plug it into I started it every other day it would be slow to start but would always start we moved about 35 miles to a location with 30amp service and we were having no problems starting it when we had to move it to dump the tanks ect. Then this last time we needed to dump the tanks it started right up we drove it about a block to dump it shut it off got it dumped it started right up we could not get into our spot because a car was blocking our spot so we we parked it on the street and shut it off and it started back up still was not room to get in our spot so shut it off again got them to move then it would not restart. Tried to jump it off a car that was v8 with no luck had someone we know to come help he said the battery to start the engine tested fine but when he looked at the coach batteries he said one was bad he unhooked the bad battery from the other coach battery and jumped started the engine battery with his jumper thing and it started right up. Got it parked shut it off. He said that we would be ok till we could get one and that disconnecting it would not affect starting it or driving it. (He said that if it needed a second battery to help start the one coach battery would be enough) but later that day we wanted to pull it up abit at the site and it would not start. Won't even turn over now with that battery is disconnected and we need to move from this site tomorrow and we don't have money for a battery till my spouse gets a paycheck should we try to reconnect the bad battery
