I wonder why Foretravel mounted the isolate outside?  Anyone ask?  JamesT?
Heat gain comes to mind.  A loose connection has caused heating enough in some posts here to physically damage the isolators.
I would think twice about relocating a electrically high load device inside the coach.
If you are moving it why not change to a much safer battery combiner?
Just asking for a friend.
It has cooling fins for a reason I assume.  Mounted outside?

Good post. Expect bad planning like quite a few other things.

Yes, combiner much better as isolaters are obsolete now. Boost solenoid could be a latching type. No current draw in either position for the solenoid itself.  High capacity battery A/B/Both/Off does away with everything else.

Brett's ON-OFF switch is the best. Nothing to fail and the switches are inexpensive. Just don't turn switch to "off" with the engine running.

Not even turning it off will do any harm-- it is idiot proof.

With switch off, the alternator B+ is still hard wired to the chassis battery.

Unfortunately with a manual switch "on" a discharge condition could kill both battery banks.

The combiner auto disconnects if either bank is being discharged.  Cannot run down and damage both banks.

My limited solar leaves my batteries slightly below the correct float voltage in winter.

Drove the coach yesterday from Orange County to near downtown LA at 3pm(yes I know. How stupid) to get blue beacon to wash it(mask time) and the release the wax from the tires as recommended by Michelin monthly and the combiner put the banks together and I wax charging at 13.96 volts for an hour or so.

After the wash on the return trip the plug in gauges in the dash said 13.87 or so on both banks.

The Javelina system showed 13.7 to 13.8.

My rudimentary system on the roof runs down the refer vent to an old controller then to the refers 12 volt hookup behind the access door.  Small wiring drops the voltage to roughly 13.6 at the batteries(combiner at this time) so it's sort of self limiting

Am hoping to install my pt-100 solar controller and AGS-N gen start as soon as I can talk my guru buddy into it.

He now runs Girards repair shop at their San Clemente location instead of fixing rv's.

Measure the wires, but I know on our 1993 all wires were long enough to move from the OE position to the electrical compartment at the foot of the bed.

Same with a 97. Plenty of slack.

Brad at FT is putting together a price to replace all. Said he just did it for someone else that bought a bunch of stuff restoring theirs
