Heart Source Manager 20 Replacement
I ordered the Magnum MS2012 Inverter/Charger, the automatic transfer switch and a subpanel to replace my existing Source Manager 20. At this point I am looking for a diagram or instructions that show how to wire the new inverter. The Source Manager 20 has AC1 In and Out wiring on the top ride side of the inverter and a Panel 1 and Panel 2 wiring on the top left of the inverter. This is for a Fleetwood 1999 American Tradition

I have a Source Manager Troubleshooting document that explains quite a bit about how it is wired to the load center. Might help you figure it out. PM your email to me and I'll send the pdf file.

Been all over this, hopefully you can make this hand written diagram out
I used a Freedom 458 dual input/dual output but the Magnum should wire up about the same

The old source manager had a contractor the opened when on battery power, it kept the A/C from running.
You'll replace the microwave beaker with a 30 amp, the microwave will then move to the new sub panel box. The 30A will then supply power to inverter/charger.
Basically you'll move all the wires that will be inverter used to the sub panel.
In my case it was microwave, TVs and outlets (4 breakers)
PM or reach out here if you got any questions or concerns

Puptruk:
I also have a 1999 Tradition with the original Heart Source. Would be interested if you'd document the install with pics and diagrams. Thanks

Do you mind sharing what the replacement project cost you? Just rough guesstimate is good enough. Mine is still working, but I see the writing on the wall.

Not at all....
Freedom 458 2500W dual input/output, from Colorado Standby- $1200
Square-D 70 amp sub panel, 4 - 20amp breakers - local Home Depot, I think were around $50 bucks
50 amp transfer switch/surge protector on Amazon - $130
So....1300/1400 bucks was blood guts and feathers.
I'm sure someone here has probably done it for less.

If yours is still working, I would suggest disconnecting power, both AC and DC (unhook battery cable)
And open the unit up. There's 4 screws holding top cover on, then on the right side of the rows of contactors, your see a handle that you use to lift open the contractor "tray" the charger/inverter is under it.
The source manager has foam insulation attached to the inside, over time the insulation falls down into the charger and causes it to overheat/fail.
Mine was full of the stuff.
Perhaps vacuum all the loose debris out of it will prolong the life....

Good advice. I had it open and found what you describe and I removed what I could. I also replaced a clogged mesh filter on the right side where it draws in air. Mine was not charging the chassis batteries when on shore power so I installed a $20 trickle charger which has kept me in operation for over a year now.

Freedom 20 replacement
Hello everyone. I was going to replace my inverter converter last spring and found out it was cold blooded. When it was below 55 degrees it wouldn't work on shore power. Worker all summer and now is in the cold and not working. Don't know if it will live this year. Has anyone relocated the system out by the batteries or in the shore compartment? Thanks John

Hello I opened the top of the unit and lifted the tray. My insulation is good. I have to use the gen to startup the converter then use a hair dryer under the cover to heat up what ever is cold. After 5 minutes of that I can turn on the shore power. Go figure

Sounds like a circuit board going bad as it contracts with the cold. Circuit boards for the old Heart products have been unavialble for years now, so you are out of luck unless you find a used one somewhere.
Does your '99 have the Heart Source Manager, which is basically a Heart Freedom inverter/charger coupled to a custom auto transfer switch? If so, it can be replaced by a newer inverter/charger and a separate auto transfer switch.
If somebody has already done the conversion from the Source Manager to separate modules, you can just install a new inverter of your choice. However, any remote control panels are probably tied to the Heart interface, so those would need to be replaced too.

I just completed the replacement process for the Heart Source Manager 20. Replaced it with a Magnum MS2012 Inverter/Charger and Surge Guard 50 Amp Transfer switch. I am about finished with the documentation with pictures and diagrams, and will post soon.
