Before spending your cash on Vanners, batteries, or flashing dash lights….
Check the connections on the back end of your 50 DN. Give them a slight tug. That bank of wires has a long problem history due to vibration.

My battery’s are 3 years old lifelines I believe, I did notice one of the connectors isn’t is the best condition, I’m going to clean them up as you recommended and report back.

Bill, I don’t recall getting that order, so you must have paid a premium.

I’m trying to digest this thread but it’s hard.
Ralf you have Lifelines for your chassis batteries? I think Napa group 31 are the way to go.
Also that dash light is for a battery low light, meaning chassis batteries low. I don’t think the Vanner has much to do with it.
You will get that light usually someone might leave basement light on with the doors open but it’s something on the 12v Prevost side. Mikee mentioned this too.

Tom you must be getting old because it did come from you about 2 years ago.

CRS.. You mentioned the word old, are you thinking of Jon instead?

Hey, quit picking on me.
Bernie I’ll try putting the light issue in context. On Vanner monitor equipped coaches there are two ways to evaluate the voltage. One is to look at the gauge. Old school, but it works. The second is if a dash light comes on. The problem with each is the gauges on most coaches do not show do not show the 12 and 24 volt chassis voltages, just the 24. The Vanner is intended to get your attention so you do look at the gauges, but if the gauge shows an acceptable voltage you should get the voltmeter and read the voltages to verify what the warning light shows.
The early 70A Vanner monitor had an unreliable history so verifying voltages usually revealed the monitor had a malfunct (a technical term)
The is no Vanner monitor in multiplexed coaches so if you do get a warnng light on a multiplexed equipped coach, as you said that is likely information you can take to the bank.

Yes A1 I understand your diagnosis.
My experience has come from all pre 06 chassis having this issue. We have always found it to be run down batteries or bad batteries. Could very well be something else.
Also I’ve seen this 3 times and it was all on Featherlite coaches, hhhmmm.

I had not thought a converter would modify a Prevost chassis warning light system, but given The unique way Vantare does the house you may be right in that they want the chassis lights to be done their way. Maybe someone familiar with Vantare can jump in and explain if Vantare gets into mods on the chassis also.

Sorry Tom I guess it was the other guy:) lol

I believe the light is tied to my house batteries, as I was at the bus the other day and I decided to unplug it and invert off the batteries and my inverters did so for about 3-5 min and the. I notice the voltage started dropping and the they shut off and gave me an error on both screens. It’s hard to believe all my batteries could have gone bad??? Or my inverters??? Voltage checks out at the equalizers doubled check. Also light does not come one when I start the bus and unplug. It takes about an hour of driving then comes on.

This might be a case of the converter adding warning lights for some house functions to the dash. That means an owner has to learn what each dash warning light is meaning. There are a lot of warning lights, some so obscure you never see them except when doing a dash light test or just after turning on the key.
Every conversion is different from another so here is a perfect example of how to get the wrong answers and end up chasing one’s tail, all perfectly understandable because the writing does not clarify where the low voltage source is.
