Harry. As I wanted to fire up my non remote FBH in the summer I spotted this post somewhere on this forum and wrote it down. To fire the FBH up with no remote:-

Model 66232C 12 volt to pin 1
Model 98570B earth to pin 3

Clarification please. Are they both correct and where is the model number?

Because of the above I didn't fire it up in the summer as a test but luckily it fired up ok the first day it got cold a few days ago.

On my 98570B later model, that number is on the label which faces you (second line up from the bottom on the left) and on a second label on the end panel which faces out to the wing.

I can confirm shorting pin 3 to ground works on my model, but obviously cannot confirm the method for the earlier one, but it seems safe to assume it is correct - so I will include it.

Everyone else - please feel free to report any errors or amendments it might need......

As requested the How to is here. If you amend or add to your OP please let me know and I will update the How To accordingly.

An excellent piece of work Harry

Time is relative so this is the easiest way of doing it :xmas-smiley-004:

BTW

Reassemble reusing the paper gasket by pushing the split back together.

Thank you Pete, got the same info from FrenchMike and he is Webasto expert, so we can conclude that 66232c board definately doesnt have kbus. Still, dont know what od 4 pin connector used for

On both types you have eath and + batt and the "loop" is connected on
pin 1 (6 pin connector)
I guess for factory tests?

I'm sure that someone's come across my problem before, but at present we're stumped.

We've used this excellent guide to overhaul 3 units now... But theres a strange issue with our latest unit (a complete retro fit). We get fuel up, unit kicks up, but doesn't fire. Did understand how the piece in the right up with the bulb should work? If you bridge a bulb across the top should it light and unit kick up? Or, does it light if glow plug ok, and that would indicate PCB fault?

Any help/advice gladly received.

Regards,

You connect the bulb in parallel, so it should light when the glow pin is active - however I believe the real reason is to reduce the resistance the ECU sees (because you've now added another path for the current) so that it thinks ignition has taken place.

If the bulb isn't lighting then either the output stage for the glow pin is bad or the conditions haven't been met for it to be switched on yet (e.g. fan or pumps failed self-test).
