Aria 3401 - Need PDM photo please

[ChiefBob]

I had my coach in Freightliner last week for the PDM recall. They tested it and said it was good. (I thought they were supposed to replace them). When I went to pick up the coach both batteries were at 11 volts. They jumped it off and I brought it home. I think I left he inverter on so I might see the house batteries getting low but I don't understand the chassis batteries. They worked on it the previous day. After charging for a while, now my inverter charger stays off most of the time and the voltage is 12.8. It was always 13.7 before the "repair". Can you please send me a picture of your Power Distribution Module in the right rear compartment so I can first see if they hooked it up right. I'm headed to Freightliner this morning but I expect them to say its a problem with the charger and take it to Thor. Here's the part I need a photo of. Thanks!

Mine is at my shop so no photo

Is the charger on but not charging?

Check the charger profile and make sure it matches your batteries

Your house and chassis batteries were both low?

[ChiefBob]

Yes the charger is on but not charging. Both batteries show 12.7 volts. Occasionally it will float charge the house at 13.4 then it shuts off and goes back to 12.7. Freightliner is going to check the pdm connections this afternoon but said they only unplugged connectors, no cables removed. We’ll see and I’ll post back

UPDATE: Freightliner folks said bring it in for a recheck. It was initially determined to be a coach where the PDM was only tested, which it passed. Upon rechecking the build number of the PDM it found to be in the group to replaced regardless of test result. They did it while I waited and, when I plugged it in at home, the charging system seems to be operating as it did before the trip to the shop. Time will tell but I'm encouraged.
