I have retro fitted a heater to my newly acquired zt-t. I bought it off eBay and although it looks pretty good, I can't be sure that it works. It's not the 232 model, but the other one.
The unit was quite straightforward to fit thanks to all of the tutorials - all of the wiring and fuel lines were there already. I have pushed some diesel through the fuel line to the engine bay and hopefully got some in the pump by using a syringe.
Next step was to test the unit, which I have tried to do by earthing pin 3 as suggested. The water pump runs briefly and the combustion fan starts up but the thing shuts down after a minute or so. Also, I don't hear the doser pump clicking at any point.
I bought a brand new doser pump from best of British so I know that THAT'S ok.
So, firstly, should I keep pin 3 earthed throughout the test, or is it just a momentary thing?
Secondly, do I just need to pull the fuse to reset a lockout, or does the engine need to be running before I pull the fuse?
Finally, unless I have made a mistake, does everyone think that the circuit board could be fried (no doser pump running)?
Thanks for your time folks,
