Battery tie solenoid

[Gardner Yeaw]

I have read the previous entries on this subject, but have one
question. Should the solenoid(s) be energised when the gen. starter
switch is pressed, or is there another method of energizing them?

In my 78F#33 I disconnected all the batteries, then reconnect the
generator battery. I hear the solenoid energize when the cable is
connected. This doesn't seem right as it will put a constant drain on
the battery. I still need to do some investigation, testing, to
determine if the power is fed back to the coach batteries, but I
thought I would start here, wiht a question.

Thanks

The solenoid is energized when the auxillary battery switch on the dash
is pushed. Unless that switch is activated, it should be open. This
prevents the coach batts from drawing down the gen batt, especially
handy when dry-camping. By isolating the gen batt, even if you run
your coach batts down too far, you will always have juice to start the
generator and get the batt chargers going. Disonnect your coach batts
and see if you have voltage on the coach side of the solenoid. If so,
replace it.

There is also a modification you might want to install if you don't
have it. BB came out with a "jumper wire" across that solenoid with a
circuit breaker and a diode. This allowed current to flow from the
coach charging system (alternator or batt chargers) to the gen batt to
keep it charged, but the doide prevented current from flowing from the
gen batt back to the coach. Provides a little extra insurance that
your gen batt will stay charged.

Scott,
Thank you. I will check out the wiring tomorrow. It will take me
some time to learn the systems on this coach, they are very
sophisticated so it's more than just a basic cause/effect approach.

Don't feel bad, I have had my coach a year and a half and I learn
something new about it every week.
