Wiring an Eberspatcher heater

Keith our Esbersparcher diesel heater is protected by circuit breaker from factory. Zero problems in 6 years of use.

Thanks for that. I think I am being sold a pup on this one.

Keith, you still haven't said what the issue is.

"Shitty" chinese wiring cannot be the problem with blowing a fuse, If dodgy enough, the wiring will reduce the current flow when heater plugs draws current and not blow a fuse. All you have done is force the start with a bigger fuse. same wiring isn't it?

Unless the fuse they supplied was under specced in the first place. Just back from a weekend camping, it ran both nights spot on.

Geeez Keith, have you walked under a ladder or something? lol

100A circuit breaker on wiring that is most likely rated for 10A-20A sounds like an electrical fire waiting to happen:(

Yes, I agree, talk about having an Elephant gun to kill a mouse. 10 times overkill by marine electrician. Maybe that is why some boats burn to the waterline.

Keith.
I know there can be faulty gear but:
The breaker CANNOT be the problem, that only ensures the wiring will catch fire before the heater does.
The amount of recirculatory airflow, which is the cool intake, and hot air exit side has to be free flow. Having the intake in a mostly sealed cupboard seems to be a large oversight by installer. ie, not much idea of the unit. It may not be specifically mentioned in the blurb but do you know of any heaters which run with a severely restricted intake airflow?
Do you really think the suppliers run a diagnostic test? They simply replace stuff to make things work. Yes, they know about replacing heater glow plugs of course.

The wiring plug. DO you mean to say the supplier could not test it because they don't know enough about what they sell to simply connect the wires in same combination, no matter which plug has been fitted to wiring. Not very good at doing anything are they?

When you say , "the heater tripped out" is it that it stopped? What tripping of what was happening? Sounds like the diesel flow is restricted or tank cap vent not
venting. You DID test it with cap off didn't you? Replacing the pump and filter is not a solution if filter is clean and passes fuel and the pump delivers to the burn chamber. There is always some smoke and burping as you start after a system fuel line bleed.
If the heater is only drawing around 2 amps at start up, then the heater glow plug is NOT working and of course the flame failure will say no flame because the hasn't been any flame.
The supplier still holding to the breaker issue indicates they have no idea of anything related to the heater apart from some info they have been forced to learn because of trouble from customers. They buy a few additional bits of heaters to have the required "stock or spares" for warranty. They will guard them closely and blame anything they can. PS. If these glow plugs are a bit voltage sensitive, then the thin Chinese wiring will allow them to work/heat and last. If supplied with great wiring, no voltage drop, while operating on a system having higher than normal system voltage it may begin to burn out any heater glow plugs everytime. Perhaps the thin wiring is there for a current control reason. They will be made to a minimal spec. Just observations from what has been said.

Crikey Keith, I'm almost sorry I asked :-)

I think RMD covered just about everything. I started out with an Eberspatcher which ran well for about ten yrs. Unfortunately it packed up 3 yrs ago along the Oonadatta track. Closest repair/parts Adelaide or Rockhampton. They are great heaters, but genuine parts are expensive, as are the heaters. Ordered a 3kw PAP heater on Ebay $499 had it delivered to Longreach and installed it in Barcalden. Recently had a minor problem with the display, contacted the seller who replaced it for the cost of postage. Clearly there are heaters and heater. Also good dealers and not so good dealers. Hope all goes well with the Eberspatcher.

Blowing air back through the line will still cause bubbles into the diesel volume even if the cap is on and the cap is blocked, because unless the tank is full of fuel you will be able to administer some air into the tank causing bubbles. and it appears OK. Unless you did that for a while to ensure continual airflow out through the caps venting hole it doesn't necessarily prove much. Do the caps on both tanks have clear holes through. If a gasket has been added then that would restrict the air inward flow. Just check it for clearance because if it is a problem no heater will work for long as the pump is just a pulse unit and not really a suction pump as such.

I think it's worse than "walking under a ladder" Keith.
You must have offended a witch!

Keith
Not a good holiday at all, makes it really hard to bear when things go wrong. Interested to know what fault is with the 200 series, ie, blown up as you mentioned. Any alert for problems is good to pass onto others so to avoid similar things happening and to take any precautions which may become apparent.

I'll start a new thread on the engine blowup once we know a bit more about what caused it. Looks at this stage like dust damage.
Compression right down on two cylinders and dust already evident in the intake ducting to the turbos. Needs a new engine.

I feel your pain, Keith, having just been through an engine replacement for my BT50. Statutory warranty job well outside manufacturer's warranty period, but with some personal choices and towing fees it cost me about $1500 - chicken feed compared to what I could have been up for, so I'm not complaining.

Good luck with yours.

Keith
Have heard of, not seen, a number of 200 series which have sucked in dust past faulty fitting air filter and airbox. Known fault with later Toyotas unfortunately. I will await your post to come of the issue. Was it dealer serviced? no excuse if so, because they knew of the problem at the outset.

Keith, you fitted new fuel pump, exhaust and air intake also?

John the fuel pump is inside the furnace and is as quiet as you like. Apart from removing the old fuel pump, the new furnace slotted straight in, with no other mods. E6verything fitted perfectly.
I have an Eberspatcher wiring loom on hand in case the Chinese one gives problems. I had the Chinese one specially shortened up to suit and am loath the replace it. Both looms come with yards and yards of cable.
Keith

Glad you got the heater sorted.

What's happening with the 200's engine replacement?

My saga hasn't finished. It started in Feb and now I have a $400 issue because they re-used a sensor that is "one-shot", ie if removed must be replaced with a new one according to the factory manual. They didn't and it failed.

It should be simple, but it won't be. They've already denied liability.

Good luck with yours

The heater is still working like a beauty and my wife reports that the hot shower now lasts a lot longer.
The mechanics have had to order a new engine mount for some reason and the vehicle won't be back till Wednesday. Denise flies home on Monday as she has patients to see.
I'll hang around Orange for a few days to make sure the vehicle runs okay plus get a bit of towing time in before returning home.
This was supposed to be a test run for our new home built off road caravan, but it hasn't seen a dirt road yet!
