Dave W Posted December 30, 2019 Report Share Posted December 30, 2019 (edited) Having recently forked out £200 for a service I thought I’d actually use it today instead of my immersion. Went to press the manual override on the timer and the red backlight went out and nothing’s happened since. Checked the two fuses near the webasto burner and they look ok. Does the timer have an internal fuse maybe? Any ideas before I lob the lot over the side? The timer is very basic and looks like it came out of a Christmas Cracker.

Fender151 Posted December 30, 2019 Report Share Posted December 30, 2019 Hi Dave, the WEBASTO can go into an error state, to reset i think, for memory, you need to take the two blade fuses out for 2 mins, reinsert, turn on the times, take the fuses out, for 2 mins, reinsert and turn timer on again.. this should clear the error and reset the unit. The process is described in the manual if you have one, or you can download one from the Webasto website. Link to comment Share on other sites More sharing options...
Dave W Posted December 30, 2019 Author Report Share Posted December 30, 2019 Yes, I’ve had that before after several attempts to fire up. This seems different I’m wondering if the timer is kaput. It’s completely blank. Guess I’ll have to try and get a tester on it. It has tiny wires and a baby multiplug on the back. Link to comment Share on other sites More sharing options...

PaulJ Posted December 31, 2019 Report Share Posted December 31, 2019 Is your Webasto a Thermotop C ? If so (and you are confident) -disconnect the timer on the three way plug and bridge terminals 2 & 3 -this should start it. If you want to double check your wires first -you should have a posi supply (pin 2-red), a neg for controller (pin 1-brown) and remaining wire (pin 3-black) which switches the webasto on. This goes to pin 3 on the big multiplug on top of webasto. Apply power to switch on. Disconnect to switch off. Fiddle at your own risk...? Link to comment Share on other sites More sharing options...
Dave W Posted December 31, 2019 Author Report Share Posted December 31, 2019 No, I don’t want to fiddle (but my son might, he’s an electrician). I guess what I’m asking is if the timer runs off a separate fuse to the Webasto heater? The two fuses in the holder next to the Diesel unit look fine although untested. Should I be looking for another fuse for the programmer or maybe a relay? The programmer has no backlight or digital readout anymore. I have no wiring diagram (Thermo top C) Link to comment Share on other sites More sharing options...
PaulJ Posted December 31, 2019 Report Share Posted December 31, 2019 Its the smaller value fuse (well should be if standard) Manual/wiring diagram here https://www.butlertechnik.com/technical_library Link to comment Share on other sites More sharing options...

True indeed - as a trainee avionics oink back when in the RAF at Cosford, learnt that rather than tear the aircraft to bits, check the circuit breaker - bloody instructors were always doing stuff like that Link to comment Share on other sites More sharing options...

rustynewbery Posted December 31, 2019 Report Share Posted December 31, 2019 Came back tut boat a few days ago and the Eber was t*ts up again. Quickly traced to a corroded fuse in the control box. Jiggled it and up she sparked. Then finally did what I should have done 16 years ago and replaced it with a modern car type spade fitting fuse with nice holder. In the process, removed about 70% redundant wiring in said box as it was to power remote fans and other stuff usually fitted to trucks & trains. So far...………. 3 minutes ago, system 4-50 said: My Dad was an instructor as Cosford! I think he was teaching Morse Code & telegraphy(?) … 1968-9 and 70-71.

WotEver Posted December 31, 2019 Report Share Posted December 31, 2019 I love Cosford. Go there twice a year - once for a Jag meet and then a couple of months later for the air show. Link to comment Share on other sites More sharing options...

My ebersparky thingy gave up a few days ago ...(I posted a thread on it) ...... and it turned out to be corroded fuses (easily cleaned up!) .....but my control box has already been upgraded and has modern type car spad fuses. They still corrode and need cleaning every few years. Link to comment Share on other sites More sharing options...
