PT Battery Banks

[krminyl@...]

Scott,

Congrats on your "new" PT....I think you'll love the difference as compared
with your FC.

I have six 6-volt Trojan T-105's, and all tied together. I installed a
Perko marine switch, and I split my batts into two banks...one bank with 4
batts,
the other with the remaining two...this way when dry camping, I can run on
my "camping bank" of 4 batts, and always reserve the other bank of two batt
for starting the 8
V92 DD if the other bank runs down. When on the road, I leave the switch
selected to the "both" position so both banks can charge.

Of course, I still have the 12-V genset battery, isolated from the Trojans,
so the genset can always (hopefully) can always be started. It seems that
the mid-80's PT have issues keeping the genset battery charged, but I think I
have a handle on that issue (replaced the large "stud" diode and a few
solenoids), and some rewiring...

Congrats again...always feel free to ask us if you have any other questions
or problems.

On my FC, there is one bank of batteries (four 6-volt Trojans) that
serve both the house and chassis functions and then one separate
battery for the generator. Are the PT batteries the same way, or do
they have split banks for house & chassis?

Thanks

I think the spit banks happened around 91. My 94Pt has 3 bats for the
engine and 8 for the house. I just installed a generator battery up
front for gen starting. Take CurtS number with you for the trip. He
has a 86pt38-8V and is up on the entire rig. Curt is one of the many
great folks of helpful knowledgable BB owners and number 8 on my speed
dial. Remember that the DD and the Cat have very different RPM ranges.
In a Detroit V92, 2000 RPM is the max even decending a hill.

Kevin,

Can you send me details about the switch you installed?

Thanks,
Scott

Gregory,

One minor point, your #8 has a '87PT38. All else appears accurate, except
possibly the RPM thingy. Have a good day.

Hi Dick, You are a diplomat. your post point out that the two facts
of my statement have "possibly minor" flaws but "All else appears
accurate". Are you confirming that in fact I own a 94pt and live in
Romoland California? Do you write political speaches or sell RV's?

You, Joyce and your son Brian are in our prayers

Hi Scott,

The battery switch I installed was a heavy duty Perko brand marine battery
switch...Guest is another brand you can probably use...it is a battery switch
used to create two banks of batteries, most common on a boat, that uses a lot
of electronics (radar, fish finders, radios) when the boat is turned off, so
if you run one battery bank down, you can always start the boat (or
motorhome) motor with the other battery bank. The switch typically is a large
rotary
switch, with a "off", "1", "2" or "Both" position. I had to make new
battery cables, and they run into the Perko switch, and out again. Just make
sure
you switch to the "Both" position when the coach motor is running, so both
banks can charge at the same time. This switch is the sure-shot battery
shut-off, and disconnects all DC battery power from the coach killing
everything...no need to use the electronic master or the DC switch underneath
the steering
column....the Perko kills everything.

Hope this makes sense! Let me know if you need any more info.

FYI
Perko switches are commonly used in ambulances. Find a company that
scraps ambulances of repairs them and you will have a source.

Hi all,

Keep in mind that boats have two banks to absolutely guarentee
cranking power when out at sea.

Generally, we can always use the generator if our large single bank
gets too low. Or call a roadside service. A modern battery combiner
will do away with the genset battery not recieving a propper charge
in a PT.

The deaper our batteries are discharged the sooner they fail;
discharge always means chemical imballance and battery dammage. This
is a non-linear relationship. So if we make our main bank smaller, so
that we can have seporate starting batteries, that main bank will now
not last as long; both from a boon docking stand point or long term
battery life.

If you really need starting batteries, you should probably add
seporate batteries for that purpose. If you want to get the most out
of your batteries, you have to monitor them closely.

My pt40 seems to have some kind of fantom load on the gen. battery, Sometimes
it stay charged sometimes not, am installing new one and would like to know your
solution for this.Marvin SkaggsBuffalo, Ky. 427161984 PT40--- On Sat 04/28,
