runaway parents Posted October 16, 2016 Report Share Posted October 16, 2016 Once the thermostat is set does the heater kick off and on like a house furnace? Link to comment Share on other sites More sharing options...
porky69 Posted October 16, 2016 Report Share Posted October 16, 2016 Are you talking about a Webasto diesel fired air heater? If so yes the thermostat functions just like the one in your home (turn furnace on/off). Link to comment Share on other sites More sharing options...
runaway parents Posted October 16, 2016 Author Report Share Posted October 16, 2016 Yes.my son was using it one night. First time we ever used it . He would get it to fire up and it would get up to temp and shut off .and would not restart. Had a truck driver tell me he had to run his about 10 degrees higher to get to kick off and on.. Just now talking to son he said when it would shut off it would shut off dome light also .Could there be a timer on this thing that he activated?

MrSeas Posted October 16, 2016 Report Share Posted October 16, 2016 If the dome light went out and the Wabasto would not start back up I'm betting the "low voltage" warning system kicked in due to low battery voltage. Next time you use the heater try hooking up a battery charger to the batteries to keep your voltage up. This might help you "duplicate" the same situation and see if the heater runs normally. You also could just run the truck to keep up the batteries and see if the heater works normally. Just a thought..... Link to comment Share on other sites More sharing options...

Nigel Posted October 16, 2016 Report Share Posted October 16, 2016 I think MrSeas is on it. When I drove for a living I turned my Webasto bunk heater on in November and turned it off in late March. Truck was never parked more than two days at a time and never had the batteries go flat.

runaway parents Posted October 16, 2016 Author Report Share Posted October 16, 2016 Yup your right went out started truck. Heater ran fine no problems shut truck off dome light went out heater shut off. Don't have a good charger .Is there a good trickle charger that I could put on it to keep batteries charged?.And if so what would you recommend? What kind voltage should charger put out?

runaway parents Posted October 17, 2016 Author Report Share Posted October 17, 2016 Typically how long does it take to charge batteries? Using a charger or just driving down the road. Don't think I have been driving it enough to keep them charged. Link to comment Share on other sites More sharing options...

It will work for all of the batteries. When to truck is sitting, I keep the Battery Minder plugged in to keep the batteries up. I have the Battery Minder mounted to one of the walls in the storage box behind the drivers seat.  Al 2012 Volvo VNL 630 w/ I-Shift; D13 engine; " Veeger "   Redwood, model 3401R ; 5th Wheel Trailer, " Dead Wood "   2006 Smart Car " Killer Frog "   Link to comment Share on other sites More sharing options...
RickS Posted October 17, 2016 Report Share Posted October 17, 2016 Do you have an inverter in the truck? If, so you may have a battery charger/inverter and may just have to plug the truck in.

runaway parents Posted October 18, 2016 Author Report Share Posted October 18, 2016 Checked inverter no way to plug it in to shore power. Its a cobra inverter dosent have a charger built in. It is a old one. May be time to up date it. Or go with battery minder. Thanks for all the help. Link to comment Share on other sites More sharing options...
RickS Posted October 18, 2016 Report Share Posted October 18, 2016 I believe the factory installs this inverter/charger. It is easy to get an external AC plug for a HDT to connect to the inverter/charger then you would have a transfer switch and be able to run on shore power and charge your battery also.

Jack Mayer Posted October 18, 2016 Report Share Posted October 18, 2016  Hi Rick,  Where would the placement for the inverter be ? Does the factory place the inverter in the storage box behind the drivers seat ?  Thanks for any help, Al Typically you mount the inverter in the drivers storage box. The location is your choice, depending on what you have in there already. Mount the cabpower someplace on the wall in there. Again, depending on what you have in there already. Be aware that inverter is a modified sine wave. Which is typically OK for a truck. But if you have sensitive electronics then you may wish to use a pure sine wave. Most people do not need that in a truck, however. Jack & Danielle Mayer #60376 Lifetime Member Living on the road since 2000PLEASE no PM's.

RickS Posted October 18, 2016 Report Share Posted October 18, 2016 That inverter is a MSW but is one of the lowest priced inverter/chargers. I had the factory install a Magnum MS2012 in my truck as it is a very good battery charger and pure sine wave inverter. I keep my truck plugged in all the time when not in use. Here is a picture from a factory 2017 Volvo and a picture of my inverter. Both mounted in drivers side storage box.  2017 VNL  Rick & Carey,Excel W41GKE Wild Cargo Toyhauler Volvo 730, D13, I-shift, 500/1850Brabus Smart Car  Link to comment Share on other sites More sharing options...
runaway parents Posted October 19, 2016 Author Report Share Posted October 19, 2016 Hi Rick I checked out our truck .I do have the kit you described .But don't have the inverter charger. Have to put this on my wish list for now. In the meantime will have to go with cheaper Battery minder. Save a couple bucks means more fuel in the tank for trips. Thanks for the help.

runaway parents Posted October 19, 2016 Author Report Share Posted October 19, 2016 Hey just thought of something regardless of the inverter. Seeing I have the kit Rick was referring to. If I plugged it into shore power can I run the webasto heater off shore power? Link to comment Share on other sites More sharing options...
RickS Posted October 19, 2016 Report Share Posted October 19, 2016 As long as you have your battery charger plugged into that shore power kit keeping the batteries above the low voltage cutout setting. The heater is running off the DC side not he AC shore power side.

The heater is running off the DC side not he AC shore power side. A trickle charger will not do what Rick suggests above....you will be using more than it is putting in. The trickle charger works well to simply maintain the bank, but that assumes no usage other than a parasitic draw.

runaway parents Posted October 19, 2016 Author Report Share Posted October 19, 2016 Evidently I have a after market inverter. The kit Rick refers to has a male plug end which I believe plugs shore power. My male plug is plugged into the inverter .Can I unplug it and plug it directly into shore power there?
