Default New to us Interstate Issues....

Hello to all,
After having an 06 T1N 118" for a while, we decided to purchase a T1N based RV. We recently (yesterday) bought a 05 Airstream Interstate, 78K miles, very good shape. My more than capable wife flew to MD from CO and picked the rig up. All went well until early today when the battery light on the dash illuminated. It became apparent that for some reason the van battery was not charging. She made it to Charlottsville, VA. It is going into a local shop that works on Sprinters to have the charging issue diagnosed.
I have come to discover that the generator does not seem to charge the van battery due to the battery isolator. I had hoped that by running the generator while driving, it would charge the house and chassis battery to allow the rig to be driven despite a non-functioning engine driven charging system. Am I correct regarding the assumption that the generator will not charge the chassis battery thru the inverter/charger?
Secondly, the generator will not stay running while the van is going down the road. LP tank is full, the unit starts up while the rig is stationary, but dies when under way. Is this common or normal?
I'm a mechanic by trade, but I'm in Colorado and the rig/wife is in VA, so I can only go by what I'm being told.
Any and all input is greatly appreciated.

Slightly off topic, but didn't your wife get stuck driving another T1N across country recently? I think you need to stop sending her and go yourself next time!

Well, sort of stuck. Had tranny issues with another T1N. Got it resolved and had a good rest of the trip.
She likes the travel and more often than not, no issues. Somebody has to stay home and work to pay for the toys....

Default Fixed, sorta....

Reman alternator installed and charging like a champ. Under 500 bucks for everything, seems more than fair.
Generator ran stationary yesterday for 40 some odd mins. with A/C on, no issues. I am going to change/check oil when it gets here, suspect a low oil shutdown situation.
Keep your fingers crossed, a few more miles yet to go....

Default Generator oil?

So just how does one go about checking the oil in this beast? Is it a crawl underneath and pop the access cover deal or is there a easier way?

No easier way that I know of, assuming it's an Onan LP generator similar to the one under my GWV Legend.

Unless you know that the generator oil has been changed recently, I would change the oil while you are under the van. It's not much more trouble than checking the oil.

Change the oil using a vacuum pump is the easy way to go. Don't over fill, pay attention to the dip stick. It doesn't hold very much. The side cover just lifts off to reveal the dipstick. (assuming it is an Onan)

Assuming it's an Onan similar to mine, you have to crawl under the rig and remove the cover. Then:
1. Unscrew the dipstick, wipe it off and reinsert it but do not screw it down. Remove the dipstick again and check for proper level.
2. Add oil as necessary.

If your gen is not the Onan LP KV series, then go the manufacturer's website and download a manual.

Good luck,
Wayne
