Thanks Joe, I’ll go take a look.

Appreciate the feed back ….

Al, e-mail sent.

never was that skinny! If it were I cramed in there it would be my last position. Glad you posted pictures for others to see what they are getting into. Me I have to remove batt etc to get access. Bob

One of the air leaks on the short list is the air adjustable steering column. Pretty common but especially in the winter.

That would sound like it’s under the dash …port side of helm.

Thank you – now the search is on to find a snap on Rep.

Dean you can pull the relay in the back engine electric compartment I think it’s relay 76 but check that out, and the brake lights won’t come on when the jake comes on.

[Per]

Fuel use and the jake are non issues, the jake turns your motor into an air compressor.

There is a fine line when letting off the throttle with the Jake on, you can coast without triggering the Jake. In 6th gear with the Jake on and cruise, you barely even notice the Jake if the cruise backs off the throttle to maintain the target speed. My Jake engages in any gear except 1st, as it should be.

Don’t ever tell a trucker you turn off your Jake, he’ll have coffee squirting out his nose.

Good to know…but it has stopped since re-setting inverters. No idea why but I’ll test the gen battery when I get to Dallas.

Peter and Tom wouldn,t be benificial to turn the retarder off on slick roads?

[Per]

Tom,

On the left side cockpit panel, next to the window, there are a set of light switch indicators. On the top row there is a push-button indicator light that says “Low Battery.”

Neither tech link or my inverters said I had a low battery, but this light blinked and alerted until I reset my inverters. In the past, the tech link monitor would turn yellow first indicating my house batteries were getting low. But my battery voltage, according to tech link and the inverter, was in the 28v range, and never was lower than 26v, so unless I’m reading it wrong, it seems like my batteries were not low.

Per,

Thanks for your inputon the jake change. I understand your custom that is comfortable for your use. I’am not sure about doing that on our bus.

I agree with Jon on this one, I’am not hunting for a button.

Who ever put the dash buttons on the dash has not driven a bus. You use the jake switch all the time but the rabbit switch is easy to punch and that’s used only when you stop. Go figure.

With the electric heater question …look for a tripped ground fault on one of the power switch boxes.

[Per]

Thanks again … It was a rookie question but I’m glad to know it now…

[Per]

Thanks Jon, I appreciate the reply. I had the transmssion retarder in another Wanderlodge and had to really pay attention to the temperature elevation.

Tim, This is part of the education you are about to receive regarding air leaks.

Some leaks are of little or no importance. Peter mentions the seat, but there are other things that remain pressurized with the key off that do not need air. I am not sure your vintage H3 has them, but as an example later model Prevost chassis have two small air manifolds. From the factory one of them has a Prevost installed solenoid valve that shuts down air to the manifold so if the air systems off that manifold do have leaks the solenoid shuts them off. The second Prevost installed manifold however does not have a shut off, so when the key is off all the systems and devices on that manifold always see pressure and thus can leak air. I looked at what was on my second manifold and saw no reason for anything on that to have air when the key is off so like Peter I added a solenoid valve.

Now I am trying to identify the remaining systems and devices on both the house and chassis that don’t need to have air when the bus is not running and I will do the same thing. Basically, when my key is off I only want air to several things, including my slide seals, dump valves, pocket doors and bed lift. I probably will send air to my generator air bags also but right now they hold air pressure without change for months on end.

Your pneumatic diagrams for the chassis on your coach will reveal if there is anything on your coach that needs air when the coach is not running. If there is allow that system to have air, but shut off everything else and you will have less leaks draining the aux tank. Your Marathon has a dedicated tank and system for the house, but there may also be house systems you would want to turn off also.

My solenoid valves are powered via the chassis electrical system and as set up only open when I turn the key on.

Tim, check with Jeff at ETLC. He has LED headlights for the four bulb systems.

They are really good and reach out a long way. I have just the low beams and they really brighten up the road.

Don’t even bother with the high beams, you won.t need them.
