Hi everyone, this is my first post and I haven't been rving very long. My chassis batteries are very very low too low to start the motor, so my house batteries are charged so I used the "aux" battery switch to try to start it with no avail. I have done this before and had no problem. When I push the rocker switch (aux batt) the dash lights up bright but then I turn the ignition to the start position the lights and low air alarm flashes on and off and that's all I see and hear. Anyone have any idea why the aux batteries wont start the motor or even try to turn it over? Thank you

Sounds like the house batteries are too low also. Jump it.

Does anyone know where the air connector is located on a 1998 HR to release the brakes? I have parked the rv to where I cant access the battery compartment. Dummy me, Im learning!

Unbelievable, I have parked my RV to where I can't access the battery compartment and I need to charge the batteries to move it. Does anyone know where the air supply is located so that I may supply air to release the brakes? Dummy me, I'm learning!

Thanks

So when you turn the key with the aux rocker flipped and the lights and buzzer running...does it dim things like it is drawing the battery down. If not - are you sure it is in neutral and everything is in the proper position to turn over. Does the genny start? You probably have it moved already - but maybe it is not the battery.....

Hi and welcome to the forum.

Since your questions have evolved to be manufacturer specific, I have moved your thread here to the Monaco owners forum where you'll get more knowledgeable views.

Best of luck.

Buddy the air supply will be on the left side of the generator bay.

Hi on the drivers side front bay you should have an air manifold where you may be able to add air to the system. You could also try at the air dryer which is on the same side but further back in the same bay as the air cleaner.

Have you tried starting the Gen and charge the batteries from there. Or have you or can you get to the power cord and charge from shore power.

Hi, yes I have charged the batteries from the shore power. I tried again to start the RV by using the "aux" batteries which are the ones I just charged. I turn the key very dim lights, push the toggle switch and all lights are very bright so I turn the key to start, all dash lights start flashing on and off buzzer goes on and off with the lights. I get no clicking or any sound from the RV motor starter. So I tried to start the genset with the aux switch and it pretty much did the same thing. Let me add we had to by pass the aux power switch with a jumper cause the switch fell apart.

If your house batteries are charged, and they should be if you are on shore power, and you press the aux start switch. If you still can't start up then your big boy solenoid is probably bad. Not uncommon.
And you can't get to the battery compartment because if the way you are parked.
On my 2001 diplomat my salesman switch relay is mounted on a board in the bay under the driver seat. On that board I have 2 heavy gauge Red wires. One from the house batteries and one from the chassis batteries. You should be able to put the positive battery charger on the chassis battery post located on the board and put the black to ground. That should charge your chassis batteries from the driver side if your rig is like mine.
