Charging Problems Freedom 458 Inverter/Charger

Have you located the large fuse in the 12 volt DC line to the batteries?

yep, that is what I would guess.

rig a test light, and use it to jumper the big fuse while trying to charge the batteries, If it lights replace the fuse.

NAPA has a replacement for $10

The 'fuse' may actually be an automotive type circuit breaker. With either shore power connected or the generator running, check the voltage across the negative and positive terminals of the batteries. You should be getting more than 12VDC; probably 13.5+ VDC. If not, connect a jumper wire across the breaker and then again measure the voltage across the battery terminals. If the voltage increases above 12VDC, then the breaker is defective. Breakers are available at most auto parts stores for $10 to $15. Hope this helps.

Everyone thanks for your replies and I will check today

What does your Freedom Panel say?
Does it show Charging, what is the voltage output?
You should have either a BIRD or BCC, which controls a Isolater relay.
Look closely at the B+ terminals or the batteries (12 V to Ground Terminal), do you see a Wire with a fuse. Is it clean?
This wire is the sensing voltage which informs the BCC or BIRD that the charge voltage is at a high enough level to close the Isolator relay.
Do you have a diagram?
Also, read the voltage on the Red & Black terminals of the Xantrex, is it above 13.5 Volts. Trace the wire from the red,

What remote panel do you have?
It should show
* Battery voltage
* AC input status
* AC Breaker size

When on shore power with the charger enabled what is the battery voltage?
It should quickly jump to 14Vdc or so if not, check for AC input status and Charger enabled status.

If the panel says all is good with no error codes.

Suggest you remove the unit from the rig and do a bench test - many times the internal transfer switch craps out.

PLEASE do not toss it in the trash if you decide to purchase a new unit. As I collect them for spare parts and repairs as time allows

Don't get confused about the fuse. It is not a small automotive. it could look like this.

Mine looks like the eBay link too. Just got back from checking it as it's right above the inverter and it checked OK.

The control panel inside the RV shows everything to be working correctly and charging. The voltage that comes out of the inverter charger matches the inside too, but the battery voltage at the batteries don't. There has to be something in between causing the loss.

You will need to follow the voltage toward the batteries. use a test light is the easiest way.
Start right at the DC terminals on the inverter and follow the positive to the batteries, then do the same with the ground.
It could be a bad connection. Some of the crimp connections covered by shrink tubing could be bad, if equipped.
Just because the display says it is working, you know it is not reaching the batteries if they are not getting charged.
