Charging house and engine batteries?

Hey guys,

Could someone please advise on quickest way to charge all batteries? I have fast car chargers and trickle chargers but don't know how to hook up. I've also plugged into 120 outlet but doesn't seem to charge up or very slow if anything.

Its a 2001 fleetwood expedition, 36t, diesel cummins.

Pics attached of actual battery compartment.

Thx in advance!

Have you ever checked the water levels in those house batteries?

Have you put a volt meter on them when it is supposedly charging?

Looking at them that would be my first question as well!

Unless they just drove 50mi of dusty dirt road.

First check water level, then CLEAN ALL TERMINALS BRIGHT, SHINY, ONE WIRE AT A TIME AND reassemble, then RECORD BATTERY VOLTAGE READINGS on each battery. Lets make sure trying to charge good batteries?

Hey guys, thx for the replies.

They look old and dusty cuz I take it out to the desert.

Batteries new at beginning of year, RV shop checked batteries and had them fully charged a couple weeks ago.

I have not checked voltage while plugged in but batteries showed 12v with meter. What would I see on meter while charging if its already at 12v or close to it? BTW, dash monitor inside shows low Volts but handheld meter shows 12v.

Can I charge the batteries with a normal car battery charger? Or both with 120v shore and separate car battery charger?

Thx again!

12.?
12.7 or higher considered charged. 12.1 considered time to charge. Just a straight 12 volts does not tell us much. I'm sure you know to NEVER let them go below 12.0.
Above numbers an example and may not be exact, just to give you an idea. Your cables look good. Believe me, I have seen worse!

Oh, might want to get a quality volt meter and see what your getting voltage wise at the batteries and compare to what your in house meter reads.

Since it's a Fleetwood coach, just plug the coach into a 120v outlet and it should charge both battery banks. Starting the coach engine also charge both.


If you want to use your external, auxiliary chargers, simply hook a jumper cable between the house and chassis battery positive posts. Any positive post in either bank will do, but the primary one (where multiple cables go) is preferred. Then hook your charger cable to one of those positive pots and either one of the battery negative posts or a chassis ground point. Both battery banks are already tied to chassis ground, so no need to jumper the negatives.

IF the isolator solenoid is functioning!

I'm already on my 2nd one and it's now not connecting both house and chassis when energizing. I'm going to pull it and clean the contacts and see if I can get another year or more out of it. Not happy with the Trombetta isolator solenoid. Perhaps a Big Boy is in the future.

Hey Robert,
Yeah, I nursed my 11 year old dual battery solenoid on our '04 Itasca Horizon 36GD with the CAT C-7 330HP for a year or more before replacing it. I'd dissassemble it and, clean the contacts and, it would work great for oh, maybe another year or so. Finally, I decided to purchase another one only, this one has the SILVER contacts in it. So far, it's going on about 4 years and it's working flawlessly. Just a thought here.
Scott

Hey Scott!
Good to hear from you!
I believe bothers the solenoids had/has the silver contacts according to the model number.

12.6-12.7=95%-100% charged, where 12.-1-12.2=50%, goal to never get below 12.0 as it greatly shortens battery life; Must wait 30-min after removing from charger to allow FALSE HIGH surface charge to dissipate before reading battery voltage. CHARGING VOLTAGE= 13.2-14.6vdc

The best charger is the one it came with. Most diesel pushers have inverter/chargers, with automatic 3 stage charging.

First you need to get that working, charging the house batteries properly.

All the back and forth about the solenoid is for charging the other battery, not your prime concern, until you get some charging on the house batteries.

You need to measure the voltage on the house batteries while on shore power. Your looking for 13.5 volts or more.

If your getting more then 12.7 volts but not 13.4 or more, find the inverter charger and unplug the phone jack looking thing marked BTS, Battery Temp Sensor, and see if the volts go up.

Do them tests and come back with what you find.
